Disconnect negative battery cable. Remove engine undercover. Place wooden block between jack and oil pan, and raise engine slightly. Remove engine mount assembly near timing belt cover.
Remove clamp for power steering return hose near timing belt cover. Remove all drive belts and tensioner bracket. See Fig. 1. Remove power steering and water pump pulleys. Rotate crankshaft clockwise so that No. 1 cylinder is at TDC of compression stroke. Remove crankshaft pulley.
CAUTION:DO NOT rotate crankshaft counterclockwise. Ensure timing marks are aligned. If reusing timing belts, mark timing belts for direction of rotation.
Remove upper timing belt cover and gasket. Remove stub bolt of engine support bracket, and remove center timing belt cover. Remove lower timing belt cover.
NOTE:Camshaft sprocket dowel pins will be in 12 o'clock position when timing marks are correctly aligned.
Ensure camshaft, crankshaft and oil pump sprocket timing marks are aligned. See Fig. 2 or Fig. 3. Loosen tensioner pulley center bolt. Move tensioner to relieve timing belt tension. Remove timing belt. Remove timing belt auto tensioner. See Fig. 1.
Remove plug from left side of cylinder block. Install a.31" (8.0 mm) diameter Phillips screwdriver into the hole against balance shaft. See Fig. 4. Screwdriver must go in at least 2.36" (60 mm) or more. If screwdriver will only go in about.79-.98" (20-25 mm), turn sprocket one revolution and align timing mark. Keep screwdriver in place until timing belt is installed. This ensures that balance shaft driven by oil pump sprocket remains in correct position.
To remove timing belt "B" (balance shaft belt), hold crankshaft sprocket stationary with a spanner wrench. Remove crankshaft sprocket bolt. Using gear puller, remove outer crankshaft sprocket.
Remove crankshaft sensing blade (if equipped). See Fig. 5. Loosen timing belt "B" tensioner bolt. If reusing timing belt "B", mark direction of belt rotation for reassembly reference. Remove timing belt "B".
