This one is from 2001. I have seen newer vehicles that have had seepage from the exhaust side corner #4 cylinder. Even cars with the newer head bolts can have the bolt stretch.
THE WARRANTY TIME FOR THIS OPERATION HAS BEEN UPDATED - PLEASE SEE INFORMATION BELOW
Date: 04/26/01
To: All Saab Dealers
Saab Service Manager
From: Rich Miller
Code: 211
Reference: External cylinder head gasket leakage, M99- 9-3 Viggen and 9-5 models; M00- 9-3 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. Please endeavor to schedule this work in such a manner that it does not inconvenience the customer by keeping the car overnight.
If any bolt does not tighten completely, that bolt must be replaced with a new bolt.
1. Unplug the connector and remove the ignition discharge module and spark plugs. Undo the crankcase breather pipe on the camshaft cover and remove the nipple for crankcase ventilation and vacuum from the camshaft cover. Remove the camshaft cover.
2. Loosen one bolt.
3. Tighten to 60 Nm (44 ft.lb.).
4. Tighten a further 90 degrees.
5. Repeat for all bolts in sequence pictured below.
6. Check and top off coolant or oil as needed.
7. Reinstall cam cover, run engine and perform a visual inpsection for leaks.
