The importance of a functioning cooling system cannot be overstated. A cooling system disruption or fault can result in total engine failure, something that can be remarkably expensive to remedy. Understanding how your cooling system works and why it needs service can save you significant amounts of money and vehicle downtime.

Why Cooling Is Critical

During normal operation of the engine in your vehicle, there is a massive amount of heat that is generated due to the constant ignition of gasoline and the friction generated by multiple moving parts (rods, pistons, shafts and gears). To prevent this heat from accumulating high enough to melt seals and warp engine components, a cooling system is necessary.

A typical cooling system is composed of a radiator, water pump, antifreeze (or an antifreeze solution) and various hoses that route the antifreeze throughout the engine. As the engine generates heat, the cooling system helps to dissipate the heat and keep the engine at an optimal running temperature. If there is a leak somewhere in the cooling system, cooling efficiency drops and the engine can begin to overheat. Also, contaminants in the antifreeze itself can cause problematic metal corrosion.

It’s for these reasons among others why vehicle manufacturers recommend having your cooling system inspected at set mileage intervals. Keeping your engine cool means keeping it running longer, healthier, and within temperature tolerances.

Common Cooling System Issues

Probably the most common symptom of a cooling system malfunction is a climbing thermostat reading. If your engine is ‘running hot’, it is highly recommended that the cooling system be inspected for leaks or other issues.

You may also notice antifreeze leaking below your vehicle, or you may be hearing a hissing sound coming from your radiator. These are indications of leaks, and leaking cooling systems are near guaranteed to fail unless the leaks can be corrected fairly quickly. Another factor that may impact how well your cooling system works is the pH balance and level of coolant. A coolant pH that is too basic or too acidic means a flush and refill is in order, and a low coolant level will result in a steadily climbing engine temperature, even when idling.

To diagnose your cooling system issue, a Thompson Automotive ASE-certified technician will inspect your radiator, thermostat, water pump, antifreeze and all hoses and connections. Once the problem is located, an expert service recommendation will be made. In addition to having professional mechanics on staff, we also use high-quality BG Cooling System Flush with every exchange.

After all work is performed, the cooling system will be topped off with antifreeze before being pressure tested for optimal functionality.
