DISASSEMBLY - LEFT SIDE
1. Disconnect negative cable from battery.
2. Use penetrating oil on all nuts and bolts to be
removed. This will prevent the possibility of broken
or stripped nuts and bolts.
3. Remove air cleaner system (note position of line and
hose connections).
4. Disconnect A.I.R. (air injection reactor) tube from
exhaust manifold.
5. Remove bolts and exhaust manifold.
DISASSEMBLY - RIGHT SIDE
1. Disconnect A.I.R. injection tube from exhaust
manifold.
2. Remove bolts and exhaust manifold.
3. Clean exhaust flange surfaces on cylinder heads at
this time.
DISASSEMBLY - CROSSOVER PIPE
1. Raise vehicle and support with jackstands.
2. Making sure the converter is cool, remove the
exhaust crossover pipe. If the pipe is frozen to the
converter, it can be heated with a Propane torch (or
equivalent) to help loosen the joint.
