A car’s engine generates
enough heat to destroy itself. The cooling system protects against damage,
keeping the engine operating within the correct temperature range. Regular
checks and maintenance help assure long life of vulnerable engine parts.
Here’s what’s involved in proper cooling system maintenance:
Inspect
radiator for leaks, corrosion. Computer controlled vehicles require
high engine temperature. Today’s smaller radiators require more
frequent care.
Be
sure you have plenty of coolant. CAUTION:
Never open or remove pressure cap when engine is hot. Never add pure
anti-freeze to the radiator. Always dilute it to half-strength with
water.
Look
for leaking hoses and connections*. Tighten loose clamps.
Check
condition of the radiator pressure cap*. Replace if rubber gasket is
damaged.
If
the engine runs too cool, the thermostat is probably at fault and
should be replaced.
Inspect
condition of hoses. Cracked, mushy or otherwise deteriorated hoses
should be replaced. To be sure, it is recommended that all belts and
hoses be changed at least once every 3 years, if not sooner.
Heater
hoses demand attention too. Look for leaks, cracks, and rotted rubber.
Replace faulty clamps.
Check
belts for wear and tension. Replace when cracked or frayed. Usual life
is about 3 years.
*Note: Pressure testing of radiator and
pressure cap assures the most accurate test. All shops are equipped with these testers.
