Notice: Use care when cleaning the old gasket from the aluminum surfaces in
order to prevent damage to the sealing surfaces.
- Clean the gasket-mating surface on the intake manifold.
Notice: Do not subject a throttle body assembly which contains the following components
to an immersion cleaner or a strong solvent:
• | Throttle position (TP) sensor |
• | Idle air control (IAC) valve |
• | Sealed throttle shaft bearings |
The cleaners will damage the electric components or sensors.
The cleaners will damage some of these components that contain seals or O-rings.
Solvents can wash away or break down the grease used on non-serviceable throttle
shaft bearings.
Never use a wire brush or scraper to clean the throttle body. A wire brush
or sharp tools may damage the throttle body components.
Do not use a cleaner that contains methyl ethyl ketone. This extremely strong
solvent may damage components and is not necessary for this type of cleaning.
- Clean the throttle body.
- Install the throttle body assembly with a new gasket to the intake manifold.
Notice: Refer to Fastener Notice in the Preface section.
- Install the throttle body retaining bolts.
Tighten
Tighten the throttle body retaining bolts to 10 N·m (89 lb in).
- Install the coolant water hoses.
- Connect the throttle body electrical connector.
Important: Ensure the throttle control cables do not hold the throttle open. With the engine OFF, check to see that the accelerator pedal is free.
- Connect the throttle cable.
- Connect the PCV hose.
- Connect the air outlet hose.
