Intake Manifold: Installation
CAUTION:
When cleaning cylinder head and block mating surfaces, do not use a metal scraper because surfaces could be cut or ground. Instead, use a wooden or plastic scraper.
- Remove covering on intake manifold and clean surface. Clean all surfaces of cylinder block and cylinder heads. Carefully install intake manifold gaskets. See Fig 2. Set intake manifold in position on engine. Install intake manifold bolts and tighten initially to 1 N.m (10 INCH lbs.). Then tighten bolts to 11 N.m (95 INCH lbs.) in sequence shown in Fig 3. Connect fuel supply hose to chassis furl tube assembly. Pull backward on quick connect fitting to ensure complete insertion. See .NOTE: Be sure that CCV hose is installed into grommet before installing intake manifold. See Fig 1.
- Connect Idle Air Control (IAC) electrical and hose connectors. Connect CCV and canister purge hoses to intake plenum. Connect brake booster hose to intake plenum. Connect ignition coils and 2 electrical connectors at rear of engine. See Figure and Figure . Install cowl cover. Connect wiring connector to throttle position sensor (TPS). Install throttle cable.
- Install air cleaner and throttle body hose assemblies. Connect intake air temperature sensor electrical connector to air cleaner assembly. See Figure. Connect battery. With DRB III Scan tool, use ASD Fuel System Test to pressurize system to check for leaks.
