the radiator cap removed, run the engine at low idle for
5 minutes, and then at high speed for 5 minutes, to
bleed air from the cooling system.
13. Top off the radiator and fill the overflow tank until the
engine coolant is between the FULL (5) and LOW (6)

2. The engine coolant pump is behind the engine cooling fan. Inspect the engine coolant pump for any signs of
engine coolant leaks.
3. If the fan pulley has any play, the bearings inside the engine coolant pump may be worn and the engine coolant
pump may need to be replaced.
