External cylinder head gasket leakage, M99-
9-3 and 9-5 models with 4 cylinder engine
To address an external oil or coolant leak from the cylinder head gasket when no engine overheating or other running complaints have occurred, it is only necessary to retorque the cylinder head bolts. Cylinder head removal and gasket replacement is not necessary in most cases.
When this condition is found, follow the procedure outlined below. Do the complete procedure on each head bolt, ONE AT A TIME, before moving to the next bolt.
Note: Engine must be cold when retorquing. Saab recommends the engine be allowed to completely cool.
If any bolt does not tighten completely, that bolt must be replaced with a new bolt.
