Torque Specifications
SPECIFICATIONS - TORQUE 3.8L
The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts must be replaced.
Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale the bolt should be replaced.
- Step 1: Bolts 1 - 8 to 61 Nm (45 ft. lbs.)
- Step 2: Bolts 1 - 8 to 88 Nm (65 ft. lbs.)
- Step 3: Bolts 1 - 8 (again) to 88 Nm (65 ft. lbs.)
- Step 4: Bolts 1 - 8 turn an additional 1/4 Turn. (Do not use a torque wrench for this step.)
NOTE: Bolt torque after 1/4 turn should be over 122 Nm (90 ft. lbs.). If not, replace the bolt.
