Troubleshooting Test Steps Values Results
1. Verify the Coolant Level
A. Verify that the coolant is filled to the correct level. If the coolant level is too low, air will get into the cooling system. Combustion gas in the cooling system will cause a reduction in coolant flow and pressure.
B. Check the cooling system for coolant leaks.
