TIMING CHAIN HOUSING | REMOVAL AND INSTALLATION
FUEL AND EXHAUST SYSTEMS
(Refer to illustration 8.6)
- Remove the timing chain and sprockets (see Section 7).
- Remove the exhaust manifold (see Section 4).
- If you're installing a replacement timing chain housing, remove the water pump (see Chapter 3).
- Remove the timing chain housing-to-belt tensioner bracket brace.
- Remove the four oil pan-to-timing chain housing bolts.
- Remove the timing chain housing-to-block lower fasteners.
- Remove the lowest cover retaining stud from the timing chain housing.
- Remove the rear engine mount nut (see Section 16).
- Loosen the front engine mount nut, leaving about three threads remaining in contact.
- Remove the eight chain housing-to-camshaft housing bolts.
- Position a floor jack under the oil pan, using an 18-inch long piece of wood (2x4) on the jack pad to distribute the weight.
- Raise the engine off the front and rear mounts until the front mount bracket contacts the nut.
- Remove the timing chain housing and gaskets. Thoroughly clean the mating surfaces to remove any traces of old sealant or gasket material.
- Install the timing chain housing with new gaskets (see illustration). Tighten the bolts to the torque listed in this Chapter's Specifications.
- The remaining steps are the reverse of removal.
QUICK-CONNECT FUEL LINE FITTINGS | REMOVAL AND INSTALLATION
- New quick-connect fuel line fittings were introduced on 1989 and later models. A special tool (available at most auto parts stores) is required to disconnect them.
- To separate the fuel lines, relieve the fuel system pressure (see Section 2), insert the fuel line separator tool into the fitting and pull the lines apart.
- To reattach quick-connect fittings, push the line into the fitting as far as possible, then pull back on it to verify that the connection is secure.
WARNING: The line must be pushed in and pulled back to verify proper connector engagement - DO NOT rely on an audible click or visual verification to check the assembly of the quick-connect fittings.
- When rubber hose is used to replace a metal line, use reinforced, fuel resistant hose with the word "Flouroelastomer" imprinted on it. Hose(s) not clearly marked like this could fail prematurely and could fail to meet Federal emission standards.
Hose inside diameter must match line outside diameter.
- Don't use rubber hose within four inches of any part of the exhaust system or within ten inches of the catalytic converter. Metal lines and rubber hoses must never be allowed to chafe against the frame.
A minimum of 1/4-inch clearance must be maintained around a line or hose to prevent contact with the frame.
