REMOVAL
Before servicing the fuel pump, fuel lines, fuel filter, throttle body or fuel injectors, the fuel system pressure must be released, refer to Powertrain Management/Fuel Delivery and Air Induction/Service and Repair.
1. Remove intake and exhaust manifold, refer to INTAKE & EXHAUST MANIFOLD.
2. Remove timing belt, refer to TIMING BELT, SPROCKETS & OIL SEALS.

2. Refer to tightening sequence, Fig. 11, and tighten cylinder head bolts in 4 steps as follows:
a. Torque all bolts 45 lb-ft.
b. Torque all bolts to 65 lb-ft.
c. Torque all bolts again to 65 lb-ft.
d. Tighten each bolt an additional 1/4 turn (90°), noting bolt torque. If bolt torque is not over 90 lb-ft after tightening an additional 1/4 turn, bolt should be replaced.
3. Reverse remaining removal installation procedure to complete installation, torquing all bolts to specifications.
