Removal and Installation

REMOVAL
1) Relieve fuel pressure.
2) Disconnect negative cable at battery.
3) Drain engine oil.
4) Drain coolant.





5) Remove strut tower bar.
6) Remove air cleaner outlet hose.





7) Disconnect following electric lead wires:
^ EGR valve coupler
^ IAC valve coupler
^ TP sensor coupler
^ EVAP canister purge valve coupler
^ Ground terminal from intake manifold
^ Heated oxygen sensor-1 and/or -2 coupler
^ CMP sensor coupler
^ ECT sensor coupler
^ Injector wire harness coupler
^ Ground wire at the coupler
^ Ignition coils couplers
^ Wire harness clamps





8) Disconnect accelerator cable and A/T throttle cable (for vehicle with A/T) from throttle body.
9) Disconnect following hoses:
^ Brake booster hose from intake manifold
^ Vacuum hose from intake manifold
^ Canister purge hose from EVAP canister
^ Water hose from bypass pipe
^ Fuel feed hose and return hose from each pipe
^ Heater hose from heater outlet pipe
^ Radiator inlet hose from water outlet pipe
10) Remove intake manifold rear stiffener.
11) Detach water pipe from intake manifold.
12) Remove cylinder head cover, oil pan, timing chain cover, 2nd and 1st timing chains, camshafts and valve lash adjusters referring to Camshaft, Engine; Service and Repair; Camshafts And Valve Lash Adjusters.





13) Disconnect exhaust No. 1 pipe from exhaust manifold.





14) Remove exhaust manifold stiffener (if equipped).





15) Loosen cylinder head bolts in such order as indicated in figure and remove them.

NOTE: Don't forget to remove bolt (M6) shown in figure.

16) Check all around cylinder head for any other parts required to be removed or disconnected and remove or disconnect whatever necessary.
17) Remove cylinder head with intake manifold, exhaust manifold and water outlet pipe. Use lifting device if necessary.

INSTALLATION





1) Clean mating surface of cylinder head and cylinder block.
Remove oil, old gasket and dust from mating surface.
2) Install knock pins to cylinder block.
3) Install new cylinder head gasket to cylinder block.
"TOP" mark provided on gasket comes to crankshaft pulley side, facing up (toward cylinder head side).
4) Install cylinder head to cylinder block.
Apply engine oil to cylinder head bolts and tighten them gradually as follows.





(1) Tighten all bolts to 53 Nm (5.3 kg-m, 38.5 ft. lbs.) according to numerical order in figure.
(2) In the same manner as in (1), tighten them to 84 Nm (8.4 kg-m, 61.0 ft. lbs.).





(3) Loosen all bolts until tightening torque is reduced to 0 in the illustrated order.





(4) Tighten all bolts to 53 Nm (5.3 kg-m, 38.5 ft. lbs.) according to numerical order in figure.
(5) In the same manner as in (4) again, tighten them to specified torque.
Tightening Torque
(a): 105 Nm (10.5 kg-m, 76.0 ft. lbs.)
(b): 11 Nm ( 1.1 kg-m, 8.0 ft. lbs.)

NOTE: Be sure to tighten Me bolt after securing the other bolt.





5) Check that key on crankshaft aligns with timing mark as shown in figure.
6) Reverse removal procedure for installation.
7) Adjust cooling fan belt tension.
8) Adjust accelerator cable play and A/T throttle cable play (for vehicle with A/T).
9) Check to ensure that all removed parts are back in place. Reinstall any necessary parts which have not been reinstalled.
10) Refill engine with engine oil, referring to Engine Lubrication.
11) Refill cooling system.
12) Refill front differential housing with gear oil, referring to Transmission and Drivetrain.
13) Refill power steering system with specified fluid.
14) Connect negative cable at battery.
15) Verify that there is no fuel leakage, coolant leakage, oil leakage and exhaust gas leakage at each connection.
16) Check ignition timing and adjust as necessary.
