Coolant is the generally accepted term for the liquid that absorbs heat from the engine and releases it through the radiator. As the coolant circulates through the system, it transfers heat to the radiator and into the air. The liquid is cooled, fed back to the engine through the cooling system, and the cycle repeats.
Coolant should be checked for both pH level and strength at regular intervals and serviced accordingly. Even so-called ‘Long Life’ coolants have been known to lose their effectiveness prematurely. See your owner’s manual or call one of our Service Advisors for more information.
Low and used coolant also causes your vehicle to be less fuel efficient. In some cases, use or low fluid can decrease your MPG by 10%.
If your coolant is left unchanged for too long, it may result in a chemical condition known as electrolysis. This can result in costly repairs or even engine replacement.
From a safety standpoint, an overheated engine won't likely pose a problem for other motorists but could leave you stranded in remote or dangerous locations.
From an environmental point of view, there is significant impact because leaking engine coolant is poisonous and could be ingested by children, pets and other animals.
