Test Cooling System
NOTE: Engine should be warmed up to test

4. With pressure applied, check all cooling system hose
connections, coolant tank, and overall engine for leaks.
If leakage is detected, correct as necessary and
pressure test system again.
If no leakage is detected, but the gauge indicated a

within the system or at the block-to-head gasket. Have
your servicing dealer or distributor correct this problem
