4A-FE and 7A-FE Engines
Disconnect the negative battery cable.
Remove the right splash shield from under the car.
Remove the RH front wheel. Lower the vehicle.
Depending on equipment, loosen the air conditioner compressor, the power steering pump and the alternator on their adjusting bolts. Remove the drive belts.
Disconnect the harness from the ground wire on the RH fender apron.
remove the through bolt at the right engine mount.
Remove the water pump pulley.
Remove the valve covers.
Rotate the crankshaft clockwise and set the engine to TDC/compression on No. 1 cylinder. Align the crankshaft marks at zero; look through the oil filler hole and make sure the small hole in the end of the camshaft can be seen.
Remove the bolts retaining the No. 3 and No. 2 timing belt covers.
Remove the crankshaft pulley.
Remove the three bolts retaining the (No. 1) lower timing belt cover. Separate the cover from the front of the engine. Remove the timing belt guide.
Loosen the mounting bolt of the idler pulley and shift it to the left as far as it will go, then temporarily tighten it. Remove the timing belt.
Remove the idler pulley and tension spring.
To remove the crankshaft pulley, hold the hexagonal head wrench portion of the camshaft with a wrench, then remove the bolt and timing pulley.

To install:
Check the idler pulley by holding it in your hand and spinning it. It should rotate freely and quietly. Any sign of grinding or abnormal noise indicates the pulley should be replaced.
Check the free length of the tension spring. Correct length is on 4A-FE engine; 1.453 inch. (36.9mm) and 7A-FE engine; 1.252 inch (31.8mm) measured at the inside faces of the hooks. A spring which has stretched during use will not apply the correct tension to the pulley; replace the spring.
On the 4A-FE engine do the following:
Align the camshaft knock pin with the knock pin groove on the pulley side with the K mark, the slide on the timing pulley.
Align the camshaft knock pin with the knock pin groove of the pulley, and slide on the pulley.
Temporarily install the timing pulley bolt. Hold the hexagonal wrench head portion of the camshaft with a wrench, then tighten the timing pulley bolt to 43 ft. lbs. (59 Nm).
Install the crankshaft pulley. Align the pulley set key with the groove of the pulley. Slide on the timing pulley, facing the flange side inwards.
Temporarilly install the idler pulley and tension spring. Install the idler pulley with the bolt. Do not tighten the bolt yet. Install the tension spring. Push the pulley toward the left as far as it will go and tighten the bolt.
Set the No. 1 cylinder to TDC of the compression stroke. Turn the hexagonal wrench head portion of the camshaft, and align the hole of the camshaft timing pulley with the timing mark of the bearing cap. Using the crankshaft pulley bolt, turn the crankshaft and position the key groove of the crankshaft timing pulley upward.
Install the timing belt on the crankshaft timing pulley. Attach the belt guide, facing the cup side outward.
Install the No. 1 timing cover and tighten the mounting bolts to 65 inch lbs. (7 Nm).
Temporoily install the crankshaft pulley, and align its groove with the timing mark “0″ of the No. 1 timing belt cover.
Check the valve timing and timing belt tension. Remove the grommet and loosen the timing belt idler pulley mounting bolt.
Turn the crankshaft pulley 2 revolutions clockwise from TDC to TDC.
Check that each pulley aligns with the marks as shown in the illustration. If the timing marks do not align, remove the timing belt and reinstall it. Tighten the timing belt idler mounting bolt to 27 ft. lbs. (37 Nm). Install the grommet and the No. 1 timing belt cover.

Measure the timing belt deflection at the SIDE point, looking for 0.20-0.24 inch (5-6mm
I posted it wrong and it should have been Answer not Question. Anyway just trying to help out folks. Beware of internet downloads and misleading info from other people..
