Your Vehicles Cooling System

Why do you need to service your cooling system if it’s never overheated?

Most of us assume that if your engine is running at the proper temperature then everything must be OK. The biggest cause of mechanical failure in your vehicle is your engine overheating. How do you get from everything is fine to suddenly overheating and causing potential engine damage?

Though it may seem sudden in the moment, it is actually a slow problem that builds over time. Your coolant circulates through your engine where it absorbs heat and then flows through the radiator where it is cooled and then returns to the engine. If the coolant can flow freely and there are no leaks then the coolant can do its job. If the coolant can’t flow freely that’s where the problems start.

The cooling system is a harsh environment; very hot, with multiple reactive materials like plastic, metal and rubber. Over time the coolant becomes corrosive. Small pieces of metal and other materials flake off and circulate in the coolant. These bits can start to clog up the small passages in the radiator, impending the coolant flow, which can cause your vehicle to overheat. Corrosive coolant can also eat away at the system and cause leaks.

New coolant is full of anti-corrosion additives. These additives neutralize the reactions that lead to corrosion. The additives are eventually used up, leaving the cooling system unprotected.

Your vehicle manufacturer will give a recommendation for when your cooling system needs to be serviced. You’re Service Advisor can also test your coolant for freeze point and check the PH level to see if it needs replacing. 

So, if you’re past the recommended service interval bring your car in and get your maintenance taken care of to prevent future issues down the road.
