2 Remove the plug (A1) from the coolant manifold and connect the pressure gauge, GE50033, to the port.
3 Start the engine and run the engine until the normal temperature of operation is obtained.
4 Make a note of the reading on the pressure gauge. The pressure supplied by the coolant pump should be
