Coolant: Testing and Inspection

Checking For Leaks Between Cooling System and Combustion Chamber

Warning: Danger of scalding!

Only perform this work after engine has cooled down.

Caution: When engine is running with cooling system depressurized, this can create steam bubbles. These cause the engine to overheat. Observe coolant temperature.

Carry out test with CO leak tester for cylinder head leak test in accordance with operating instructions of equipment manufacturer.





In the event of a leak, the color of the test liquid turns yellow by the carbon dioxide (combustion gas) entering the cooling system.
