A cooling system is
needed to dissipate excess heat created during the internal combustion
process.
Cooling System Maintenance
Cooling system maintenance is preventive maintenance done to avoid an
overheating situation and to avoid electrolysis (the breakdown of
metals that occurs inside the engine block). Cooling system maintenance
mileage varies by make and model. ln some cases, maintenance is
necessary before the mileage indicated in the owner's manual. For
example, if the manufacturer's recommendation is a coolant flush at
150,000 miles, it could quickly need to be flushed before that. If the
coolant is low then there may be a leak. Leaks can occur at the water
pump, heater core, hoses, radiator, and at multiple locations
throughout the engine.
When checking the coolant at home, be sure never to open the radiator while the engine is hot.
Flushing the cooling system will not correct an overheating concern. if
your vehicle is overheating, (as indicated on the temperature gauge on
the dash), it would need to be diagnosed and repaired.
