Exhaust System Installation (Fig. 5)
1. Make sure the engine is off.
IMPORTANT: If exhaust studs were removed from
engine cylinder head, thoroughly clean threads in
head and apply Loctite #277 (or equivalent) to stud
threads before installing studs into head.
NOTE: Make sure exhaust plate and engine exhaust
manifold sealing surfaces are free of debris or damage
that may prevent a tight seal.

exhaust gasket on the engine exhaust manifold.
NOTE: To ensure proper exhaust system sealing,
mount all exhaust system components loosely before
fully tightening any fastener.

make sure that all fasteners are properly tightened.
