8. ENGINE COOLANT TEMPERATURE IS EXCESSIVELY HIGH OR LOW
Step 1. Check for low coolant level.
WARNING
Hot coolant may be released when radiator cap is
removed. Allow engine to cool before removing
cap. Open cap part way to ensure that pressure in
cooling system is released, then remove cap.
Remove radiator cap. Coolant level should be about 3 inches (7.62 cm) below filler neck.
If coolant level is below operating level, refill radiator with MIL-A-46153 coolant. Restart engine.
After engine is warm, check oil pressure and water temperature. Oil pressure should be 18 psi
(124 kPa) at 1200 rpm. Water temperature should be between 160-185°F (71-85°C).
