Cylinder Head Installation for Cadillac Catera 1999

1. On the driver's side of the engine, install the new cylinder head gasket with OBEN/TOP imprint toward the front of the engine.



2. On the passenger side of the engine, install the new cylinder head gasket with the OBEN/TOP imprint toward the rear of the engine.
3. Install the cylinder head to the engine block ensuring adequate clearance from all wires, components, etc.




Important: Use new cylinder head bolts. The required tightening method stretches the bolts, therefore the cylinder head bolts are not reusable.

4. Install the new cylinder head bolts (1 thru 8).
