Reasons Why Your Car Is Overheating and What To Do About It

Keeping a fleet of vehicles running smoothly is no small feat. With constant mileage and heavy usage, even the most reliable trucks can develop issues if not properly maintained. Recognizing early warning signs and knowing some quick fixes can help you avoid costly downtime and ensure vehicles are always ready for the road. When you need to schedule fleet vehicle maintenance or repairs in Mesa, AZ, give the team at Murphy Family Auto Repair a call. Spotting the Early Warning Signs One of the first things to watch for is unusual noises. If you start hearing grinding, clunking, or squealing sounds from your vehicle, it could be a sign that components like brakes, suspension, or even the transmission are wearing out. Another red flag is a noticeable drop in performance. If a vehicle hesitates, struggles to accelerate, or exhibits reduced fuel efficiency, it might be time for a thorough check-up. Warning lights on the dashboard—like the check engine or ABS indicators—should never be ignored either. These signals are often the vehicle’s way of telling you that something isn’t quite right. Common Repairs and Quick Fixes Brake System Repairs Fleet vehicles face heavy braking demands. If you notice squeaky brakes or a soft pedal, it might indicate worn brake pads or air in the brake lines. A quick fix can often be as simple as replacing the pads and bleeding the brakes. Regular inspections can catch this before it escalates into a more serious problem. Tire Issues Tire wear is another frequent problem. Uneven tread wear, bulges, or low pressure are common indicators that it’s time to either balance, rotate, or replace your tires. Maintaining proper tire pressure is a quick fix that improves fuel efficiency and extends tire life. Fluid Leaks and Low Levels Whether it’s engine oil, transmission fluid, or coolant, leaks and low fluid levels can cause major problems if not addressed. A visual inspection for puddles under the vehicle can help identify leaks early. Often, a simple repair such as replacing a worn seal or topping off fluids can prevent further damage. Suspension and Steering Issues Worn-out shocks, struts, or misaligned wheels can lead to uncomfortable rides and increased wear on tires. If you notice excessive bouncing or drifting while driving, a quick visit to a mechanic for an alignment or suspension check can be all it takes to restore smooth performance. Fleet Vehicle Maintenance in Mesa Fleet vehicles tend to spend a lot of time on the road, meaning they’ll generally require maintenance more often than a daily driver. At Murphy Family Auto Repair, our team is equipped to handle the service needs of all types of fleets, such as light-duty work trucks, including diesel trucks powered by Cummins, Power Stroke, or Duramax diesel engines, rental cars, taxis, delivery vans, police cars, mail trucks, and other company vehicles.

Driving through desert terrain poses unique challenges for your car. The intense heat, dusty conditions, and sporadic rain can take a toll on your vehicle if you’re not prepared. Below are some essential maintenance tips to keep your car running smoothly in desert conditions. When you need maintenance services to keep your desert driver in top shape, visit Murphy Family Auto Repair in Mesa, AZ. Keep an Eye on Your Cooling System Desert heat can be brutal on your engine, making a well-functioning cooling system a top priority. Regularly check the coolant levels and ensure the radiator, hoses, and thermostat are in good condition. If your engine overheats, it can cause severe damage. Protect Your Tires The scorching temperatures can weaken your tires, increasing the risk of a blowout. Inspect your tires frequently for signs of cracking, uneven wear, or low tread. Make sure they’re inflated to the correct pressure, as heat can affect tire pressure significantly. Change Air Filters Regularly Deserts are dusty, and that dust can clog your air filter, reducing engine efficiency. Replace your air filter more often than usual to prevent dirt from restricting airflow to the engine, ensuring optimal performance. Check Your Battery High temperatures can shorten your battery’s lifespan. Test your battery regularly to ensure it holds a charge, and clean off any corrosion from the terminals. It’s also wise to carry jumper cables in case of an unexpected failure. Clean and Protect the Exterior Dust and UV rays can harm your car’s paint and trim. Wash your car regularly to remove abrasive particles, and apply a protective wax or sealant to shield it from sun damage. Consider a windshield sunshade to protect your interior from cracking and fading. Auto Maintenance in Mesa Our professional technicians offer maintenance services in Mesa for all makes and models.

Caring for your car's battery is essential in a desert climate, where extreme heat can significantly impact its performance and lifespan. High temperatures accelerate battery fluid evaporation and can cause internal damage, leaving you stranded if your battery fails unexpectedly. Follow our tips to keep your battery in peak condition in the harsh desert environment. When you need battery service or a replacement in Mesa, AZ, visit Murphy Family Auto Repair . Regular Inspections Extreme heat can exacerbate existing battery issues, so regular inspections are vital. Check the battery terminals for corrosion, which can interfere with electrical connections. Look for any cracks or leaks in the casing, as these are signs that the battery may need replacing. Keep It Clean Dust and debris, common in desert areas, can accumulate on the battery's surface, causing it to overheat. Clean the battery regularly using a damp cloth and a mixture of baking soda and water to remove grime and neutralize any acid residue. Check Fluid Levels Most car batteries in desert climates are exposed to rapid fluid loss due to evaporation. If your battery is not sealed, periodically check the electrolyte levels and top them off with distilled water as needed. This simple maintenance step can prolong your battery’s life. Protect Against Heat Excessive heat is the biggest enemy of car batteries in desert climates. Consider investing in a battery insulation kit, which can shield the battery from extreme temperatures. Park in shaded areas or garages whenever possible to reduce heat exposure. Drive Regularly Frequent driving keeps the battery charged and prevents it from losing power. If your car sits idle for extended periods, consider using a trickle charger to maintain the battery’s charge. Replace When Necessary In desert climates, car batteries typically have a shorter lifespan of two to three years. Be proactive and replace your battery before it fails, especially if you notice signs of declining performance.

Your car's steering system is crucial to its safety and control. When something goes wrong, handling and maneuverability worsen, increasing the likelihood of accidents. Knowing the warning indicators can help you intervene before problems worsen. When you need steering wheel repair in Mesa, AZ, visit Murphy Family Auto Repair . Difficulty Turning the Wheel One of the most evident signs of a steering problem is increased resistance or "stiffness" when turning the wheel. This may be a sign of low power steering fluid, a broken power steering pump, or other steering system issues. It's time for an inspection if turning becomes a major exercise. A well-working steering system should feel smooth and responsive. Unusual Noises When Turning Squealing, moaning, or groaning sounds when you turn the wheel can occasionally be a sign of steering issues. Usually, these sounds indicate problems with the power steering fluid level or pump. If the issue is not resolved, more serious problems could arise, like a damaged steering rack or even a complete power steering failure. Vibrating Steering Wheel When turning or driving at high speeds, a vibrating steering wheel may be a sign of problems with the suspension or steering system. An uneven grip on the road brought on by loose or worn-out steering components could impair your control. Since a vibrating steering wheel could also indicate unequal tires or issues with wheel alignment, have it diagnosed by an expert mechanic. The Car Pulls to One Side Misalignment is usually the reason why your car pulls to one side or drifts. Wear and tear on the steering components may potentially be the cause of this. Ignoring it could lead to uneven tire wear and worse fuel economy. A comprehensive alignment and steering check can improve driving safety and ease. Power Steering Fluid Leaks Fluid leaks are a clear sign of danger. If you notice scarlet or pink power steering fluid underneath your car, treat it seriously. Steering assistance can stop entirely if there are leaks in the steering pump, hoses, or connectors. Auto Repair in Mesa When you need steering wheel repair, turn to Murphy Family Auto Repair.

An oil leak can be more than just an annoying stain on your driveway—it can signal serious engine issues if left unresolved. If your car is leaking oil, it’s important to diagnose the problem early and take steps to avoid costly repairs. When you need oil leak repair in Mesa, AZ, visit Murphy Family Auto Repair . Common Causes of Oil Leaks Worn Gaskets or Seals Due to heat, pressure, and aging, gaskets and seals can degrade or crack, preventing oil from escaping the engine. Common areas prone to leaks include the valve cover gasket, oil pan gasket, and crankshaft seals. If these components wear out, oil can start seeping through, creating leaks. Loose or Damaged Oil Filter The oil filter keeps contaminants out of your engine. If the filter is improperly installed, over-tightened, or damaged, oil may leak from the area. It’s a relatively simple fix but one that should be addressed promptly to avoid engine damage. Oil Pan Damage The oil pan is located at the bottom of the engine and can become dented or punctured if you hit a large object on the road or run over debris. A damaged oil pan can result in a steady oil leak. While oil pan repairs or replacements can be more labor-intensive, they are essential for preventing further issues. Failing Oil Pressure Sensor A faulty oil pressure sensor can sometimes cause oil to leak from where it is installed. In addition to leaking oil, this can lead to inaccurate oil pressure readings, potentially masking more serious issues. What You Can Do Check Oil Levels Regularly Monitor your oil levels regularly. If the oil is low, top it off until you can get the car inspected, but don't ignore the underlying problem. Low oil levels can lead to severe engine damage. Identify the Leak Source Inspect the areas around the engine, oil pan, and oil filter for signs of leaks. You may notice oil dripping or pooling in certain spots, helping you identify the problem's location. For more complex issues, an experienced mechanic will use diagnostic tools to trace the source. Auto Repair in Mesa Oil leaks should not be left untreated. Bring your car to a qualified auto repair shop for a thorough inspection. Whether it’s a simple gasket replacement or a larger issue like an oil pan repair, addressing the leak early can save you from bigger problems down the road.

A range of indications are built into your car to let you know when something isn't right. Ignoring these weird noises and warning lights could result in expensive repairs or even unsafe conditions. Below, we go over the main indicators that your car needs repairs right away. When you need emergency auto repair in Mesa, AZ, visit Murphy Family Auto Repair . Check Engine Light One of the most important signals is a check engine light that flashes or stays on. It could be caused by an engine problem or a leaky gas cap. Get it checked out right away because waiting can cause greater damage and more costly repairs. Strange Noises from the Engine Something is wrong if you hear squealing, grinding, or knocking sounds coming from under the hood. These noises may indicate bearing wear, deteriorating belts, or even an impending breakdown in the engine. Larger engine troubles can be avoided by taking care of these concerns early on. Brakes Squealing or Grinding The sound of your brakes squealing frequently indicates that your brake pads are getting thin, while grinding could be a sign of metal-on-metal contact, which can harm your rotors. For safety's sake, get your braking system checked out right away if you hear any strange noises. Smoke from the Exhaust or Hood Smoke from your exhaust could be a symptom of an oil leak, but smoke under the hood might be a sign of a fluid leak or overheating.

Spark plugs may be small, but they play a huge role in keeping your engine running smoothly. Each spark plug is designed to deliver an electric spark that ignites the air-fuel mixture in the engine's cylinders, sparking the combustion process that powers your vehicle. Without them, your engine wouldn’t be able to generate the power needed to move your car. When it’s time to replace your spark plugs in Mesa, AZ, visit Murphy Family Auto Repair . Spark Plug Failure Over time, spark plugs can wear out or become fouled by carbon deposits, oil, or other contaminants. This can lead to several issues, including rough idling, difficulty starting the engine, and a noticeable drop in performance. You might also experience engine misfires, where the engine stumbles or hesitates, especially when accelerating. These symptoms are not just annoying—they can also lead to more serious engine problems if left unaddressed. One of the main reasons spark plugs degrade is the intense environment they operate in. Spark plugs are exposed to high temperatures, pressure, and a continuous barrage of explosions within the engine's cylinders. Over time, this environment takes its toll, and the gap between the electrodes can widen, making it harder for the spark to jump across and ignite the fuel mixture. This can reduce fuel efficiency and increase emissions, costing you more at the pump and potentially leading to a failed emissions test. Spark Plug Maintenance in Mesa Regular maintenance and timely replacement of your spark plugs are key to keeping your engine in peak condition. Typically, spark plugs need to be replaced every 30,000 to 100,000 miles, depending on the type and material. Some modern vehicles use iridium or platinum spark plugs, which have a longer lifespan, but even these will eventually need to be replaced. When your vehicle starts getting poor fuel economy, misfires, has performance issues, or otherwise just doesn’t seem to be running right, it may be time for a car tune-up service. During an engine tune-up, your vehicle may undergo a variety of minor auto maintenance services, such as installing new spark plugs, replacing the air filter and fuel filter, or completing fuel injection cleaning. Give Murphy Family Auto Repair a call at (480) 597-8097 to request an estimate for the cost of a tune-up for your car in Mesa, AZ.

If you’re wondering whether your vehicle would benefit more from synthetic or conventional oil, understanding the differences can help you make an informed decision. We discuss the primary distinctions between these two oils below. When it’s time for a full-service oil change in Mesa, AZ, visit Murphy Family Auto Repair . Synthetic Oil Synthetic oil is formulated with chemical components that provide improved performance. It outperforms conventional oil in terms of engine wear protection, extreme temperature performance, and longevity. This means you won't have to change it as often, which is useful for people who drive a lot or prefer less frequent maintenance. Furthermore, synthetic oil contains additives that clean the engine, reduce sludge buildup, and increase efficiency. Conventional Oil Conventional oil, which is produced directly from crude oil, is less expensive and more commonly available. It is ideal for older engines or cars with simple engine designs. When using standard oil, oil changes should be performed regularly, usually every 3,000 to 5,000 miles. This type of oil is adequate for everyday driving and provides basic engine protection. It offers less performance and protection than synthetic oil, especially in harsh conditions. Which Should You Choose? The decision between synthetic and traditional oil is based on your driving habits, vehicle type, and budget. If you drive in extreme temperatures, tow heavy loads, or own a high-performance vehicle, synthetic oil is the superior option due to its increased protection and extended lifespan. For regular vehicles and daily driving, conventional oil is sufficient and more affordable. Full-Service Oil Changes in Mesa Routine oil changes are required to keep your car’s engine healthy. How often your vehicle needs this service will depend on its make and model, but most need it every 3,000 to 5,000 miles, though some can go 7,500 miles or more. At Murphy Family Auto Repair, we offer a full-service oil change that includes the proper amount of synthetic oil or conventional oil, based on vehicle needs, a new oil filter, and an inspection to inform you of any potential issues. Give us a call at (480) 597-8097 to schedule a fast oil change in Mesa or visit our local lube shop at your convenience the next time your car is due.

Your vehicle’s water pump is crucial to its cooling system. Controlling the engine's temperature is essential to maintaining smooth operation. Knowing the functions of the water pump and how to maintain it will help avoid costly and frustrating repairs. When you need water pump maintenance or repair in Mesa, AZ, visit Murphy Family Auto Repair . What Does the Water Pump Do? Coolant is pumped through the radiator and engine via the water pump. By transferring coolant from the radiator into the engine block, where it absorbs heat, it helps maintain the ideal operating temperature. After that, the hot coolant is returned to the radiator and dissipates its heat into the surrounding atmosphere. This constant cycle guarantees that your engine operates effectively and prevents overheating. How to Maintain Your Vehicle’s Water Pump Regularly check for wear and tear. Examine the area surrounding the pump and its connections for leaks, rust, or corrosion. If there is a leak in the water pump, the engine may overheat. Make sure there is always the appropriate amount of coolant in your car. Low coolant levels can cause the water pump to overheat. Listen for Unusual Noises It is common for a failed water pump to produce a whining or grinding sound. If you detect any sounds coming from the engine's front, get a qualified mechanic to examine your car. These sounds can be a sign of an old bearing or other internal problems with the water pump. Check the Drive Belt The water pump is usually driven by the engine’s timing belt or serpentine belt. Check these belts frequently for wear indicators such as fraying or cracking. A sudden water pump failure and engine overheating can result from a damaged belt. Water Pump Maintenance and Repair in Mesa Whenever you get your car serviced, have the cooling system inspected. Mechanics can detect possible issues early on and make sure that every part—including the water pump—is operating as it should. When you need water pump services, turn to Murphy Family Auto Repair. To ensure that you’re able to quickly and safely get back on the road, we use computer auto diagnostic tools, allowing our knowledgeable ASE-certified technicians to service your car effectively and efficiently. At the first sign of car trouble, give our local car shop a call at (480) 597-8097 to schedule expert auto repair in Mesa.
