Hello and thank you for choosing Just Answer.
What size motor?
I will do this in 2 posts. One to Adjust if the belt is not removed and the second to Remove & Install. The second post will also have diagrams and pictures.
*Use this adjustment procedure if the belt was not removed.
See Figures 1 through 12
Fig. Fig. 1: After raising the vehicle, remove the right inner splash shield from the vehicle
Fig. Fig. 2: After removing the attaching bolts, pull the pulleys off of the flanges-no puller tool is necessary
Fig. Fig. 3: Timing belt cover attaching fasteners for non-Turbo III models
Fig. Fig. 4: Support the engine with a floor jack, then remove the engine mount through-bolt
Fig. Fig. 5: Rotate the crankshaft until the engine is at TDC for No. 1 cylinder, then matchmark the sprockets
Fig. Fig. 6: When at TDC, the camshaft sprocket hole should be at 12 o'clock
Fig. Fig. 7: Loosen the timing belt idler pulley, then remove the belt
Fig. Fig. 8: After the belt is removed, the idler pulley can also be removed
Fig. Fig. 9: Before installing the timing belt, make sure that the engine block and sprockets' timing marks are aligned-the crankshaft and intermediate shaft timing marks should be aligned as shown
Fig. Fig. 10: Use Special Tool C-4703 to tension the timing belt-the tool should drop to within 15 degrees of the horizontal
Fig. Fig. 11: To double check the engine timing, position the engine at TDC for No. 1 cylinder on compression stroke, then remove the small timing hole plug-the small hole in the sprocket must be centered in the timing belt cover hole

To perform this procedure, you will need a special tool No. C4703, or equivalent, to apply specified tension to the timing belt. Be careful not to allow the timing belt to come in contact with oil or any solvent, otherwise the teeth will be weakened.
If the timing marks are not perfectly aligned, poor engine performance and probable engine damage will result!
If the timing marks are in line, but slack exists in the belt between either the camshaft and intermediate shaft sprockets or the intermediate and crankshaft sprockets, the timing will be incorrect when the belt is tensioned. All slack must be only between the crankshaft and camshaft sprockets.
