To test the radiator and cooling system for leaks,
use the procedure that follows:
DO NOT loosen the filler cap or pressure cap on a
hot engine. Steam or hot coolant can cause severe
burns.
1.
After the engine is cool, loosen the pressure cap
to the first stop and let the pressure out of the
cooling system. Then remove the pressure cap.
2.
Make sure the coolant is over the top of the

The gauge reads normal, but the engine is too hot and a

2.
The gauge shows that the engine is hot, but no
