- Drain engine coolant. Release fuel pressure. See FUEL PRESSURE RELEASE under REMOVAL & INSTALLATION. Remove exhaust and intake manifolds.
- Note locations and disconnect all necessary electrical connectors, ground wires, vacuum hoses, fuel hoses, coolant hoses and control cables for cylinder head removal. Plug all fuel hoses to avoid leakage.
- Remove spark plug wires from spark plugs. Remove all drive belts. Remove water pump pulley. Remove timing belt. See TIMING BELT. Remove camshaft/rocker cover.
- Remove front exhaust pipe. Remove intake manifold support bracket. Loosen all cylinder head bolts evenly in sequence, in 2-3 steps. see scheme 2 Remove bolts and cylinder head assembly.
Installation
Install cylinder head gasket, cylinder head assembly and bolts. Tighten cylinder head bolts in 2 steps and in sequence to specification. see scheme 2 See TORQUE SPECIFICATIONS TABLE at the end of this article. To complete installation, reverse removal procedure.
Scheme 4
Disconnect negative battery cable. Remove drive belts and crankshaft pulley. Remove water pump pulley, timing belt covers and timing belt. See TIMING BELT under REMOVAL & INSTALLATION. Use Crankshaft Lock Tools (49-S120-710 and 49-B011-102) to lock crankshaft sprocket into position. Remove crankshaft sprocket bolt. Remove crankshaft sprocket using steering wheel puller. Pry out seal.
- Apply light oil coat to seal lip, and push seal over crankshaft. Tap seal into oil pump body until it is flush with edge of pump body. DO NOT bottom seal in pump body. Align keyway slots, and install crankshaft sprocket by tapping lightly using brass hammer. DO NOT deform sprocket end with hammer, or pulley misalignment may result.
- Install Woodruff key with tapered side toward oil pump body. Install crankshaft sprocket lock bolt. Using Crankshaft Lock Tools (49-S120-710 and 49-B011-102), lock crankshaft sprocket into position. Tighten lock bolt to specification. See TORQUE SPECIFICATIONS TABLE at the end of this article.
- Install timing belt. See TIMING BELT under REMOVAL & INSTALLATION. Install timing belt covers, pulleys and drive belts. Reconnect negative battery cable, and ensure timing is correct.
