Disconnect negative battery cable. Loosen power steering lock bolts and nuts, and remove tension from power steering and air conditioning compressor drive belt. Remove power steering and air conditioning drive belt.
Loosen and remove generator bolts. Remove water pump pulley. Remove crankshaft pulley and timing belt guide plate. Remove upper and lower timing belt covers.
Turn crankshaft so that timing mark on crankshaft sprocket is aligned with timing mark on engine.
Ensure "I" mark on intake camshaft sprocket is aligned with mark on cylinder head cover, and "E" mark on exhaust camshaft sprocket is aligned with mark on cylinder head cover. See Fig. 4.
CAUTION:DO NOT move camshaft or crankshaft once timing marks have been correctly positioned.
Loosen tensioner pulley lock bolt.
While protecting timing belt with a rag, remove tensioner pulley. If belt is to be reused, mark direction of timing belt rotation for proper reinstallation. Remove timing belt.
Install tensioner pulley. Pull tensioner pulley to its furthest point, and tighten lock bolt. Check that timing mark on crankshaft sprocket is aligned with timing mark on engine.
Ensure that camshaft sprockets are aligned with marks on cylinder head cover.
Install timing belt onto crankshaft sprocket first, then idler pulley, exhaust camshaft sprocket, intake camshaft sprocket, and finally, tensioner pulley.
Ensure there is no looseness in belt between idler pulley and exhaust camshaft sprocket, or between intake and exhaust camshaft sprockets.
Loosen tensioner pulley lock bolt, and allow tensioner spring to apply tension to timing belt. DO NOT add additional tension. Tighten tensioner pulley lock bolt to specification.
Rotate crankshaft two full turns (clockwise only), and align timing mark on crankshaft sprocket with timing mark on engine block.
Ensure that marks on camshaft sprockets align with marks on cylinder head cover.
If marks do not align, remove timing belt and repeat process from tensioner installation.
Measure timing belt deflection by applying moderate pressure midway between camshaft sprockets. If deflection is not 0.39-0.50" (11-13 mm) with 22 lbs. (10 kg) of force applied, repeat installation process from tensioner installation.
Install lower and upper timing belt covers, timing belt guide plate and crankshaft pulley. Install water pump pulley. Tighten all bolts to specification.
Install generator belt and adjust tension. Install power steering and air conditioning drive belt, and adjust tension. Connect negative battery cable.
