6 Important Components of a Car’s Cooling System
The Mobile Wrench Mechanic Services • 6 August 2024
A car’s cooling system is essential for maintaining the engine’s optimal temperature, ensuring it operates efficiently and prevents overheating. This complex system includes several key components, each playing a critical role in managing engine temperature. At The Mobile Wrench, we provide mobile cooling system repair in the greater Oklahoma City area. Here’s a look at six main parts of a car's cooling system.
Radiator
The radiator is a central component of the cooling system. It’s a heat exchanger located at the front of the engine bay, allowing coolant to release heat into the air. The radiator contains a series of thin tubes and fins through which the hot coolant flows. As the coolant passes through these tubes, air flowing through the radiator dissipates the heat, cooling the coolant before it returns to the engine.
Coolant
Coolant is a fluid that circulates through the engine and radiator, absorbing and transferring heat away from the engine. Proper coolant levels are crucial for the cooling system's efficiency and the engine’s health.
Water Pump
The water pump is responsible for circulating the coolant throughout the cooling system. The pump moves coolant from the radiator through the engine and back again. A well-functioning water pump ensures that coolant is consistently flowing, which helps maintain the engine’s temperature and prevent overheating.
Thermostat
The thermostat regulates the engine’s temperature by controlling the flow of coolant into the radiator. When the engine is cold, the thermostat remains closed, allowing the engine to reach its optimal operating temperature quickly. Once the engine is warm enough, the thermostat opens, allowing coolant to flow to the radiator for cooling. This helps ensure that the engine runs at the correct temperature for efficiency and performance.
Radiator Hoses
Radiator hoses are flexible tubes that transport coolant between the engine and the radiator. These hoses need to be in good condition to prevent leaks and ensure proper coolant flow.
Cooling Fans
Cooling fans help regulate the temperature of the radiator. When the engine gets too hot, the cooling fans turn on to increase airflow through the radiator, helping to dissipate heat more effectively.

Your vehicle’s alternator plays a vital role in keeping the battery charged and powering the electrical systems while the engine is running. When the alternator starts to fail, your car may exhibit a variety of warning signs that shouldn't be ignored. Recognizing the early signs of trouble can help you avoid being stranded. At The Mobile Wrench, we provide expert mobile alternator replacement in the greater Oklahoma City area. Here are five signs that it might be time to replace your alternator. Dead Battery Although batteries can die on their own due to age, a frequently dead or weak battery may point to a problem with the alternator. The alternator’s job is to recharge the battery as the car runs. If it’s not doing this effectively, the battery won’t have enough power to start the vehicle or support electrical functions. If your battery is relatively new but keeps losing charge, the alternator could be the underlying issue. Dimming/Flickering Lights One of the most noticeable signs of alternator trouble is when your headlights or dashboard lights begin to dim or flicker. The alternator is responsible for maintaining a steady flow of electricity. When it’s failing, the lights may not receive enough consistent power, causing them to appear weak or unstable. If you notice lighting issues while driving at night, it’s worth having your charging system checked. Electrical Accessory Failures A failing alternator can lead to malfunctioning electrical components such as power windows, door locks, air conditioning, or infotainment systems. These features require consistent electrical power, and when the alternator can’t keep up, they may slow down or stop working altogether. Unusual Sounds Strange noises coming from under the hood may be an indication that your alternator is wearing out. A failing alternator may produce a grinding or whining noise, often caused by worn-out bearings or belt problems. Warning Light on the Dashboard Modern vehicles commonly include a dashboard warning light that signals charging system issues. This light is usually shaped like a battery or reads ALT or GEN. If this warning comes on and stays illuminated, it’s a warning sign that the alternator is not functioning properly. Ignoring this light can lead to more serious problems and leave you stuck with a vehicle that won’t start.

A road trip should be an enjoyable and stress-free experience, but a poorly maintained vehicle can quickly turn an adventure into a disaster. Before hitting the open road, it’s essential to have a trusted mechanic inspect and service your car to ensure it’s ready to roll. At The Mobile Wrench, we provide expert mobile auto maintenance in the greater Oklahoma City area. Here’s a look at four important maintenance tasks before a road trip. Engine and Fluid Service Your engine is the heart of your vehicle, and it must be in peak condition for a long road trip. The mechanic will check and replace essential fluids, including engine oil, coolant, power steering fluid, and brake fluid. Clean and properly topped-off fluids help prevent overheating, maintain lubrication, and ensure all components function efficiently. An oil change is especially crucial if it's nearing the recommended service interval. Tire Inspection Tires are the only point of contact between your car and the road, making their condition critical for safety and performance. It’s important to ask the mechanic to check the tread depth to ensure your tires have enough grip for various road conditions. It’s essential to also inspect for cracks, bulges, or uneven wear that could lead to a blowout. Also, properly inflated tires improve fuel-efficiency and overall driving stability. Brake System Evaluation Reliable brakes are essential for safe driving, especially on highways or in mountainous terrain where sudden stops may be required. The mechanic will inspect the brake pads, rotors, calipers, and fluid levels to ensure everything is in proper working order. If needed, the mechanic will replace any worn-out components to ensure your braking system is fully functional before you begin your journey. Battery and Electrical System Check A dead battery is one of the most common reasons for roadside breakdowns. Before heading out, the mechanic should test your battery’s voltage and inspect the terminals for corrosion. If the battery is weak or nearing the end of its lifespan, it’s best to replace it before the trip. They will also check the alternator and starter to ensure the electrical system is charging and functioning correctly. This includes testing headlights, taillights, turn signals, and windshield wipers to ensure maximum visibility and safety.

A healthy suspension system plays a critical role in ensuring a smooth and safe driving experience. It absorbs shocks from uneven roads, maintains tire contact with the pavement, and helps keep your car stable during turns. But as they age, suspension components can wear out or become damaged, leading to noticeable problems. At The Mobile Wrench, we provide expert mobile suspension repair in the greater Oklahoma City area. Here are five common signs that your vehicle may have suspension trouble. Excessive Bouncing After Hitting Bumps When your car continues to bounce excessively after driving over a bump or pothole, it’s a strong indication of worn-out shocks or struts. The suspension system is designed to absorb these impacts and stabilize the vehicle quickly. If the bouncing persists, the shocks or struts might need replacement. Uneven Tire Wear Uneven tire wear can point to several issues, but one common cause is a failing suspension system. When the suspension cannot keep the tires properly aligned or maintain consistent pressure, tires may wear unevenly. This not only reduces tire lifespan, but can also compromise handling and safety. Pulling or Drifting During Turns If your car feels like it’s pulling or drifting to one side when you turn, it could indicate a problem with the suspension system. Worn-out shocks can prevent the suspension from keeping the vehicle stable during sharp turns, increasing the risk of losing control. Nose Diving When Braking When braking, your car should remain relatively level. If the front end of your vehicle dips significantly when you hit the brakes, it’s often a sign of failing shocks. This issue can increase stopping distances, posing a potential safety hazard. Rough Ride A key function of the suspension system is to provide a comfortable ride by absorbing imperfections in the road. If you start feeling every bump or dip in the road, your suspension may no longer be effectively doing its job. This issue is often caused by worn-out shocks, struts, or other suspension components.

Regular oil changes are one of the most important aspects of maintaining a healthy vehicle. While it may be tempting to delay or skip them altogether, neglecting this crucial service can lead to costly repairs and reduced performance. At The Mobile Wrench, we provide mobile oil changes in the greater Oklahoma City area. Here are five important reasons to stay current with oil changes. Protect the Engine from Wear and Tear Your engine contains numerous moving parts that generate heat and friction as they operate. Motor oil acts as a lubricant, reducing friction and preventing excessive wear on these components. Over time, oil breaks down and becomes less effective, which can lead to harsher metal-on-metal contact. This wear and tear can cause significant damage to your engine, leading to expensive repairs or even a complete engine replacement. Regular oil changes ensure that your engine has fresh, clean oil to keep things running smoothly. Improve Fuel-Efficiency As oil ages, it becomes less effective at reducing friction within the engine. This increased friction forces the engine to work harder, which in turn reduces fuel-efficiency. When you keep up with oil changes, your engine operates more efficiently, allowing you to get better gas mileage. Help Prevent Engine Overheating Engine oil plays a critical role in regulating the temperature of your engine. By lubricating moving parts and reducing friction, oil helps to dissipate heat. However, old or dirty oil loses its ability to perform this function effectively. If left unchanged, it can increase the risk that your engine will overheat, leading to serious mechanical problems. Prolong Engine Life A well-maintained engine is more likely to last longer, providing you with years of reliable service. By keeping up with regular oil changes, you help minimize the buildup of sludge and debris that can clog vital engine components. Clean oil allows your engine to operate more smoothly, reducing the likelihood of breakdowns and extending its overall lifespan. Maintain Manufacturer’s Warranty Many vehicle manufacturers require regular oil changes as part of their warranty agreements. Failing to adhere to the recommended maintenance schedule can void your warranty, leaving you responsible for the full cost of any repairs. By keeping up with oil changes and documenting each service, you help ensure that your warranty remains valid.
