Odd Engine Noises You Shouldn’t Ignore
Engine Masters Automotive • May 23, 2025
Your car’s engine makes many kinds of noises, but not all of them are normal. If you hear something unusual, it could be a sign that something’s wrong. Ignoring strange sounds might lead to serious and expensive damage. Here are five engine noises you shouldn’t ignore and what they might mean. When you need engine repair or replacement in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive.
Knocking or Pinging
That rhythmic tapping sound, especially when accelerating, could point to an issue with your engine's combustion. This is often caused by improper fuel-to-air ratios or low-octane gas. Left alone, it can lead to serious engine damage, like worn bearings or piston issues.
Squealing Under the Hood
A high-pitched squeal when you start the engine or turn on accessories like the AC usually means a worn or loose serpentine belt. If that belt breaks, you could lose power steering, charging capabilities, or cooling; not a good situation to be in while driving.
Hissing Sounds
Hissing under the hood can signal a vacuum leak, an overheated engine, or leaking coolant hitting a hot surface. Any of these can lead to performance issues or overheating. Hissing means it needs to be checked ASAP.
Grinding When Starting
If your engine makes a grinding sound when you turn the key, your starter motor or flywheel might be on its last leg. Repeated grinding can worsen the damage quickly, so don’t let this noise slide.
Loud Bang or “Backfiring”
That startling bang coming from the tailpipe or engine bay is a backfire. It’s usually caused by unburnt fuel igniting in the exhaust system, often due to faulty spark plugs, sensors, or timing problems. Backfires can damage your exhaust and signal deeper engine trouble.

In Arizona’s scorching heat, your car’s cooling system works overtime, and at the heart of that system is the water pump. This small but mighty component plays a huge role in keeping your engine from turning into a steaming mess. Knowing the signs of a failing water pump can help you avoid a major breakdown in the desert sun, which we break down below. When you need auto repair in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive. What Does the Water Pump Do, Anyway? The water pump moves coolant from the radiator through the engine and back again, ensuring that the temperature stays in the safe zone. Without it, the engine would quickly overheat, especially in hot climates like Mesa’s. Telltale Signs Your Water Pump Is on Its Way Out Coolant Leaks If you’re noticing bright green or orange puddles under your car, that could be coolant leaking from the water pump. Over time, seals and gaskets wear out, leading to drips and puddles that should never be ignored. Overheating Engine If your temperature gauge is spiking or you’re seeing steam under the hood, it’s a red flag. A failing water pump can’t circulate coolant effectively, causing the engine to overheat, something you definitely don’t want in Arizona. Grinding or Whining Noises A worn-out water pump bearing can make strange sounds. If you hear high-pitched whining or grinding from the front of the engine, get it checked out; it could be the water pump crying for help. Rust and Corrosion If you pop the hood and see rust or corrosion around the water pump, that’s a sign it’s been leaking internally for a while. This buildup can cause the pump to seize or fail.

Living in a desert climate has its perks; endless sunshine, beautiful landscapes, and no need to shovel snow. But extreme heat and dry conditions can be tough for your car's engine. If you want to keep your vehicle running smoothly in the desert, you’ll need to understand its unique challenges and how to combat them. When you need engine repair or replacement in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . Overheating Risks In the desert, temperatures can easily soar past 100°F, putting immense stress on your engine. The cooling system has to work overtime to prevent overheating, and if your radiator, hoses, or coolant levels aren’t up to par, you could find yourself stranded with a steaming engine. Regularly checking and topping off coolant is a must in hot climates. Oil Breakdown Happens Faster Engine oil is essential for keeping your car’s moving parts lubricated, but high temperatures cause oil to thin out and break down more quickly. Because of this, it loses effectiveness, resulting in increased friction and wear. To prevent engine damage, follow a more frequent oil change schedule with high-quality, heat-resistant oil. Dust and Sand Can Clog Components Desert environments mean more airborne dust and sand, which can clog air filters and work their way into your engine. A dirty air filter restricts airflow, reducing performance and fuel efficiency. Checking and replacing air filters more often than usual will help your engine breathe easier. Battery Life Takes a Hit Heat speeds up chemical reactions inside your battery, causing it to degrade faster. In desert climates, car batteries often have a shorter lifespan, so keep an eye out for signs of a weakening battery, such as slow starts or dimming lights, and be proactive about replacements. Protect your engine by staying on top of coolant levels, oil changes, air filter replacements, and battery health to prevent costly repairs.

When it comes to vehicle maintenance, not all cars are created equal. The differences between Asian and domestic vehicles go beyond their origins; they extend to design philosophies, part availability, and service requirements. We cover what you need to know to keep your ride in top shape. When you need maintenance services for your domestic or import vehicle in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotiv e in Mesa, AZ. Parts Availability and Costs One of the most notable differences is the availability and cost of replacement parts. Domestic vehicles, like those from Ford, Chevrolet, and Dodge, often have parts that are easier to source and more affordable due to widespread manufacturing within the U.S. Asian vehicles, such as those from Toyota, Honda, or Nissan, may require parts that are imported or specialized, which can increase costs. However, their parts often last longer, balancing the equation in the long run. Design and Engineering Philosophy Asian vehicles are often lauded for their reliability and efficiency. Brands like Toyota and Honda prioritize longevity and ease of use, leading to fewer maintenance demands overall. On the other hand, domestic vehicles often focus on power and performance, with designs that cater to a wider range of customization and repair options. This can make domestic vehicles more accessible for DIY repairs. Specialized Maintenance Needs Asian vehicles might require more specialized care, especially with components like transmissions or hybrid systems. Mechanics who specialize in Japanese or Korean brands are often trained to handle these specific systems, ensuring optimal performance. Domestic vehicles, meanwhile, tend to follow more standardized practices, making general repair shops more equipped to service them. Fuel Efficiency and Wear Asian vehicles are known for their fuel efficiency and tend to have less wear and tear on key systems over time. Domestic cars, with their emphasis on larger engines and rugged performance, may require more frequent servicing, particularly for drivetrain components. Which Is Easier to Maintain? The answer depends on your priorities. If you value reliability and fewer trips to the shop, Asian vehicles might be the way to go. If you prefer easier access to parts and a broader range of service options, domestic vehicles have the edge. Asian & Domestic Auto Repair in Mesa At Engine Masters Automotive, our facility is equipped to service all American, Japanese and Korean cars, trucks, vans, and SUVs. From routine services to complex repairs, we’ll keep your vehicle running strong. Our state-of-the-art Mesa auto repair shop is geared up and ready to service your car or truck.

Your engine block is the backbone of your car’s engine, housing critical components like cylinders, pistons, and coolant passages. When it cracks, it’s a big deal. But how can you tell if your engine block is cracked, and what causes this issue? We break it down below. When you need engine repair or replacement in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive in Mesa, AZ. Signs of a Cracked Engine Block Overheating Engine One of the first signs is persistent overheating. A crack in the engine block can allow coolant to leak, reducing its ability to keep the engine cool. If you’re constantly topping off coolant or seeing the temperature gauge spike, it’s time to investigate. Coolant and Oil Mixing If you notice a milky, frothy substance under your oil cap or in the dipstick tube, it’s a sign that coolant and oil are mixing. This happens when a crack lets these two fluids mingle, which is bad news for your engine. Visible Leaks A cracked block can cause coolant or oil to leak externally. Check for puddles under your car, especially if they’re green, orange, or brown. These leaks may also give off a sweet smell if coolant is involved. Decreased Performance A cracked engine block can lead to low compression in the cylinders, causing your car to lose power, misfire, or run rough. Exhaust Smoke White or bluish smoke from the exhaust could indicate coolant or oil entering the combustion chamber, a common result of a cracked block. Causes of a Cracked Engine Block Extreme Temperatures In cold climates, insufficient antifreeze can cause water in the engine to freeze and expand, cracking the block. Conversely, excessive heat from poor cooling can also lead to cracks. Age and Wear Over time, metal fatigue from constant heating and cooling cycles can weaken the block, making it more susceptible to cracks. Manufacturing Defects Though rare, flaws in the casting process can lead to weak spots in the engine block, which may eventually crack under stress. What’s Next? A cracked engine block isn’t something you can ignore. Minor cracks might be repairable, but in severe cases, replacing the engine or block is the only solution. Regular maintenance, including checking coolant levels and addressing overheating promptly, can help prevent this costly problem. Engine Block Repair and Replacement in Mesa Engine Masters Automotive is run by expert technicians who understand the complexities of engine repair in Mesa. If your car is giving you trouble under the hood, bring it to us, and we’ll let you know your options for engine block repair or replacement using a quality used new, or rebuilt motor.

Brake fluid plays a vital role in your vehicle’s braking system, ensuring you can safely stop by transferring force from the brake pedal to the brake pads. However, over time, brake fluid degrades, compromising its ability to perform effectively and putting your safety at risk. Understanding when to perform a brake fluid flush is key to maintaining your car’s performance and safety. When you need brake repair or maintenance in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . Why Brake Fluid Needs Regular Maintenance Hygroscopic brake fluid absorbs moisture from the air over time. This moisture lowers the fluid’s boiling point, making it more likely to vaporize under the intense heat generated during braking. When brake fluid boils, gas bubbles form, leading to a “spongy” brake pedal and reduced braking efficiency. Additionally, degraded fluid can corrode internal brake components, leading to costly repairs. Signs It’s Time for a Brake Fluid Flush Spongy or Soft Brake Pedal A brake pedal that feels unusually soft or requires more effort to engage could indicate moisture contamination in the brake fluid. Brake Warning Light Many modern vehicles have a brake warning light that illuminates when there’s an issue with the braking system. While this can signal various problems, low or deteriorated brake fluid is often a common culprit. Dark or Murky Brake Fluid Fresh brake fluid is typically light amber or clear. If the fluid appears dark or cloudy in the reservoir, it may be contaminated and in need of replacement. Decreased Braking Performance If your brakes feel less effective, particularly after prolonged use or during hard stops, it could be due to old, compromised brake fluid. This is especially relevant for drivers in stop-and-go traffic or hilly areas, where braking systems experience extra stress. How Often Should You Flush Brake Fluid? Most manufacturers recommend flushing brake fluid every two to three years, depending on your driving habits and vehicle type. High-performance vehicles or those subjected to frequent use may require more frequent attention. Refer to your owner’s manual for specific recommendations and have your brake fluid checked during routine maintenance. Brake Repair and Maintenance in Mesa Your car’s brakes are its most important safety feature. If you notice any difficulties bringing your car to a stop, head to our local brake shop. We can complete a brake job that includes brake fluid flushes, brake pad replacement, brake rotor replacement, brake master cylinder repair, and other services to maximize the safety of your ride.

Getting into your car, turning on the engine, and hearing nothing is one of the most frustrating things you can experience. When your car won't start, you might feel trapped, but you can get back on the road quickly by understanding the typical causes. When you need automotive repair in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . Dead Battery One of the most common reasons a car won't start is a dead battery. Over time, batteries lose their charge, especially if they are old or if you have kept lights or electronics running when the car is not in use. If your dashboard lights are dim or you hear a clicking sound when you turn the key, this is likely the problem. If the vehicle isn't starting, try starting it using a set of jumper cables and another vehicle. It could be time to replace the battery, though, if it does not last long. Faulty Starter When you start your car, the starter is responsible for flipping the engine over. If you hear only one click or none at all when you turn the key, the starter may not be operating correctly. In this case, a specialist will need to replace or repair the starter motor. Bad Alternator If the car starts but dies quickly, the alternator could be the cause. The alternator charges the battery when the vehicle is moving; if it isn't functioning correctly, your battery will quickly run out of power. An alternator replacement is a common remedy. Fuel System Issues Even if your car cranks, it might not start; this could be a fuel system issue. Gas cannot enter the engine due to a malfunctioning fuel pump or a clogged fuel filter. While certain issues require professional diagnosis and repair, regular fuel filter changes can help prevent more problems. Ignition Switch Problems The ignition switch may be the cause if your car is silent when you turn the key and the battery is in good condition. If this component is unable to send the signal for the engine to start, the car will remain off even if the battery is operational.

Driving a manual transmission vehicle offers more control, but it also requires careful handling to avoid unnecessary wear and costly repairs. Below, we discuss the key mistakes to avoid when operating a stick shift. When you need transmission services in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . Resting Your Hand on the Gear Shifter Keeping your hand on the gear shifter might feel natural, but it can put pressure on the transmission’s internal components, leading to premature wear. Always return your hand to the steering wheel after shifting. Riding the Clutch Resting your foot on the clutch pedal even slightly, known as riding the clutch, can cause friction and wear out the clutch plate. Make sure to disengage the clutch when not shifting fully. Using the Clutch to Hold on a Hill Using the clutch to keep your vehicle stationary on an incline, instead of the brake, puts unnecessary strain on the clutch. Instead, use the handbrake to prevent rollback while shifting into first gear. Skipping Gear Changes Skipping gears when upshifting or downshifting can strain the gearbox. Always follow a smooth sequence through the gears to avoid jerky transitions and mechanical issues. Coasting in Neutral Coasting downhill or toward a stop in neutral reduces control over your vehicle, as you lose the ability to accelerate quickly if needed. Stay in gear to maintain full control. Transmission Service in Mesa Avoiding these common mistakes ensures a longer lifespan for your manual transmission and a smoother driving experience. Treat your clutch and transmission carefully, and your car will reward you with reliable performance. When you need transmission maintenance or repairs, visit Engine Masters Automotive in Mesa. Our facility is staffed by technicians who can perform expert automatic transmission repair, CVT transmission repair, or manual transmission repair.

The timing chain is a critical component of your vehicle’s engine that keeps it running smoothly. In Mesa, where driving conditions can be tough due to the hot, dry climate, keeping your vehicle’s timing chain in top condition is especially important. If neglected, a failing timing chain can lead to severe engine damage, costly repairs, or even complete engine failure. When you need to replace your vehicle’s timing chain in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . What Does the Timing Chain Do? The timing chain is responsible for synchronizing the crankshaft and camshaft rotation, ensuring that the engine's valves open and close at the right time during each cylinder's intake and exhaust strokes. This synchronization is essential for the engine to operate efficiently. Unlike timing belts, which are made of rubber and require more frequent replacements, timing chains are made of metal and are designed to last much longer. However, they are not invincible and will eventually wear out over time. Why Replacement Is Needed One of the primary reasons to replace your timing chain is to avoid the disastrous consequences of a broken chain. If the timing chain snaps while driving, the engine's internal components become unsynchronized, leading to a collision between the pistons and valves. This can cause extensive damage to the engine, often requiring a complete overhaul or replacement. By replacing the timing chain before it fails, you can prevent these costly repairs and ensure your engine continues to run smoothly. Another reason to replace the timing chain is to maintain optimal engine performance. A worn timing chain can stretch over time, leading to a drop in engine efficiency. Rough idling, engine misfires, and a decrease in power are common signs of timing chain failure. If you notice any of these symptoms, it’s important to have your vehicle inspected by a professional mechanic.

You can breathe new life into an old vehicle by replacing its engine. We discuss what you need to know if you're thinking about replacing yours. When you need engine repair or replacement in Mesa, AZ, or the surrounding areas, call or stop by Engine Masters Automotive . When Should You Consider Engine Replacement? Engine replacement is typically considered when critical components fail or repairs are no longer cost-feasible. Severe engine damage, worn-out parts, and chronic mechanical faults that cannot be fixed with routine maintenance are also common grounds for replacement. If your car has suffered a catastrophic failure, such as a thrown rod or broken block, replacement may be your best alternative. Types of Replacement Engines Replacement engines come in three main types: New Engine - A brand-new engine is the most reliable and long-lasting, but it is also the most expensive. The process provides a new beginning for your vehicle and is typically covered by a warranty. Rebuilt Engine - A rebuilt engine has been disassembled, inspected, and fixed or replaced where necessary. This alternative is less expensive than a new engine and strikes a reasonable mix between reliability and expense. Used Engine - A used engine from a donor car is the most cost-effective choice. However, it has additional risks, such as unknown wear and potential hidden damage. It should be thoroughly inspected before installation. Cost Considerations The cost of engine replacement varies greatly based on the type of engine and the brand and model of the vehicle. A new engine can cost thousands of dollars, however a remanufactured or used engine can cost much less. Labor costs for installation should also be considered since they can add significantly to the overall budget. Choosing the Right Mechanic Replacing an engine is a complex task that demands experience and precision. It's best to get a reliable and skilled technician for the work. Look for mechanics who specialize in your vehicle's make and model and have received positive feedback from previous customers.
