TORQUE SPECIFICATIONS

CAUTION: This engine uses "Torque To Yield Bolts". Always use new cylinder head bolts to ensure leak-tight assembly. Torque retention with used bolts can vary, which may result in coolant or compression leakage at the cylinder head mating surface.





Install the cylinder head on the head gasket and install the ten new bolts in three steps.
- Step 1: Tighten to 34-47 Nm (25-35 ft. lbs.).
- Step 2: Tighten to 61-75 Nm (45-55 ft. lbs.).
- Step 3: Rotate an additional 85-90 degrees.
