DISASSEMBLY
DRIVER SIDE
1. Disconnect the negative battery cable from the battery.
2. If a car lift is not available, raise the vehicle 2 feet or higher and support it with adequate
safety stands. Make sure the vehicle is on a flat solid surface and is stable.
3. Apply penetrating oil to all nuts and bolts to be removed.
4. Drain the radiator and save the anti-freeze.
5. Remove and mark all spark plug wires and then remove all spark plugs.
NOTE: Grasp the spark plug boot, not the wire, and use a twisting motion while pulling
the wire from the plug.
6. Remove motor mount nut from under the cross member.
7. Remove factory bellhousing / engine support brackets.
8. Remove nut from ball and socket end of pitman arm and separate the center link from the
pitman arm and allow it drop out of the way.
9. Cut the head pipe back approximately at the location of where the header exits, then,
remove the exhaust manifold.
PASSENGER SIDE
1. Remove oil filter and right angle adaptor if so equipped.
2. Remove idler arm bolt from frame and allow center link to drop.
3. Cut the head pipe back approximately at the location of where the header exits, then,
remove the exhaust manifold.
CLEANING
4. Replace the spark plugs finger tight so debris will not get into the cylinders during the
cleaning operation.
5. Remove any gasket material or any carbon deposits that remain on the head surface. The
use of a gasket removal agent will ease the removal of any gasket material. We
recommend the use of a sharp gasket scraper to remove the bulk of material and to finish
the operation with a sanding block to provide a clean flat sealing surface.
6. After cleaning is complete remove the spark plugs again.
ASSEMBLY
DRIVER SIDE (Note: Driver side must be installed first)
1. Remove the motor mount bolt and lift the engine approximately 1-2 inches.
2. Apply a THIN film of Ultra Copper Hi-Temp Sensor-Safe Silicone Sealer to each side of
the header gasket and stick the gasket to the header flange. Masking tape can be used
to help hold the gasket to the header.
3. Place header into position:
Note: It will be necessary to install the starter simultaneously when putting the header
into place. Bolt in the starter then let the engine down carefully. Be sure not to crush the
header while letting the engine down.
4. Install the motor mount bolt and tighten securely.
5. Re-assemble the steering linkage.
