PROBLEM:

INLET MANIFORD GASKET - COOLANT LEAK • Coolant level, difficult to maintain. • Visual coolant leak from inlet manifold gasket. • Engine may eventually overheat. • Coolant in No. 1 cylinder / misfire

CAUSE:

• Relaxation of inlet manifold fixings resulting in external or internal coolant loss. • Distorted / damaged inlet manifold gasket due to overheating.

ACTION:

At the first opportunity, either during remedial work or at the next service visit check the colour of the identification tag on the inlet manifold gasket (arrowed in illustration below). If the tag is GREEN, the correct gasket is fitted. If the tag is BLACK, replace the inlet manifold gasket using the procedure detailed below. This Service Action supersedes Technical Bulletin 002, Cooling Section.
