Cylinder Head Installation On
Audi 5000 Diesel Engines
After being sure the cylinder head and engine block mating surfaces are thoroughly clean, install the cylinder head gasket DRY. NO SEALING COMPOUND SHOULD BE USED.
Install the cylinder head and torque the cylinder bolts in the sequence shown in three steps as follows:
1st Torque to 50 N·m (35 ft. lbs.)
2nd Torque to 70 N·m (50 ft. lbs.)
3rd Torque to 90 N·m (65 ft. lbs.)
Start the engine and run it to operating temperature. The cooling fan should cycle on.
Stop the engine and retorque the bolts to 90 N·m (65 ft. lbs.) without backing off.
After about 1000 miles of operation, retorque the head bolts again. With the engine hot or cold, follow the same sequence as above and loosen each head bolt (one at a time) 30° and retorque it again to 90 N·m (65 ft. lbs.).
