If you don't have the full answer you may end up in trouble. It would seem that if your engine is running at the proper temperature that everything must be OK? But the fact is that engine overheating is the most common cause of mechanical failure for engines. So how do you get from “everything is fine” to suddenly overheating and potential engine damage?
Truth is, it’s not a sudden process, and it’s often an invisible one. Your engine coolant circulates through your engine where it absorbs heat and then flows through the radiator where it is cooled – and then back to the engine again. As long as the coolant is able to flow freely – and there are no leaks – then the coolant can do its job. This is the point where drivers have to look deeper.
The cooling system is its own environment: very hot, with a number of reactive materials like various types of metal, plastics and rubber. Over time the coolant becomes corrosive. Small pieces of metal and other materials flake off and circulate in the coolant. As these bits start to clog up the small passages in the radiator, they restrict the coolant flow, leading to overheating. Corrosive coolant can actually eat away at the system and cause leaks as well.
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.
This is why your service advisor and the team at Auto Select provides recommendations for when your cooling system should be serviced. We can also test your coolant for freeze point and PH to see if it needs to be replaced (if you've added straight water to the system these numbers may be off). You need to get fresh coolant in there to continue to protect against corrosion.
So drivers who've gone beyond the recommended service interval should take care of this maintenance service to prevent unnecessary repairs down the road. Check out this month's savings on service for your vehicle's cooling system.
