With the timming marks lined up make sure that cylinder 1 is at top dead center on the compresion stroke, then as you lower the distributer back in make sure that the rotor is pointing to the number 1 plug wire post on the distributor cap,mark the distributor where the #1 post is since you can't install it with the cap on.

timing mark is on flywheel for crank and on the rear end of the cams under the rocker cover.be carefull with this as the pulleys do not have keyways and can come loose resulting in smashed valves and piston.make sure retaining bols have locktite or better still araldite on the threads and use a impact gun on them.fairly easy job to do though,make sure you remove tensioner though and remove the dust cover and give a little drop of oil and some new grease then push seal cover back on ,saves the cost of a new bearing as these are not cheap.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
2. Loosen and position the power steering pump mounting bracket and position it aside.
3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
5. Remove the timing belt.

1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
2. Install the crankshaft pulley and belt guide.
3. Install the timing belt cover.
4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
5. Position the alternator and drive belts, then adjust and tighten it to specifications.
6. Start the engine and check the ignition timing. Adjust the timing, if necessary.
