Exhaust Manifold: Service and Repair

Exhaust Manifold Removal and Installation
1. Relieve the fuel pressure.
2. Loosen the drain plug in the radiator, and drain the engine coolant.
3. Remove the under-cowl panel.
4. Disconnect the evaporative emission (EVAP) canister hose (A) and brake booster vacuum hose (B).





5. Remove the quick-connect fitting cover (A), then disconnect the fuel feed hose (B).





6. Disconnect the heater hoses.





7. Remove the rocker arm oil control solenoid.
8. Remove the intermediate shaft heat shield.
9. Remove the cover and exhaust manifold bracket, then remove the exhaust manifold.





10. Install the exhaust manifold and tighten the bolts and nuts in a crisscross pattern in three steps, beginning with the inner bolt.
11. Install the other parts in the reverse order of removal.
12. Inspect for leaks: Turn the ignition switch to ON (II) (do pot operate the starter) so the fuel pump runs for about 2 seconds and pressurizes the fuel line. Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
13. Refill the radiator with engine coolant, and bleed air from the cooling system with the heater valve open.
