This is an inteference engine so you need to check if the valves are damaged.
1. Disconnect negative battery cable. Remove all necessary air ducts. Position No. 1 cylinder at TDC of compression stroke. Align timing
marks. See Fig. 1. Remove fan and fan shroud. Remove accessory drive belts. Remove water pump pulley. If necessary, remove radiator
and splash guard.
2. Prevent engine from rotating, and remove crankshaft timing pulley. Remove upper and lower timing belt covers. See Fig. 2. Remove spring from tension pulley. Loosen adjusting bolt and move pulley toward water pump. Remove timing belt.
Some procedures may differ slightly due to engine construction.
Ensure No. 1 cylinder is at TDC when rotating camshaft, or damage may result.
1. Pull tensioner fully toward water pump side, and temporarily tighten retaining bolt. Ensure No. 1 cylinder is at TDC on compression stroke by rotating crankshaft until keyway aligns with mark on front crankshaft seal housing (12 o'clock). Rotate camshaft until timing mark on cam gear (arrow) aligns with mark on upper camshaft cover (notch). See Fig. 1.
2. Position timing belt over crankshaft sprocket, oil pump sprocket, camshaft sprocket and tensioner in that order. Ensure belt is positioned in sequence given and without slack between sprockets. Loosen tensioner pulley adjusting bolt allowing spring tension to tighten belt. Tighten adjusting bolt temporarily.
3. Temporarily install crankshaft pulley bolt and rotate crankshaft 2 complete revolutions in opposite direction of engine rotation, until marks on crankshaft and front oil seal retainer are aligned again. See Fig. 1. Loosen tensioner lock bolt, allowing tensioner spring to fully adjust tension. Tighten tensioner lock bolt.
4. Install timing belt covers. To complete installation, reverse removal procedures.
