The only Tempo/Topaz engine which utilizes a timing belt is the 2.0L diesel. This engine has a timing belt at the front and rear of the engine.
The timing belt is a cogged type rubber and cloth constructed belt which functions as the link between the upper cylinder head of the engine and the lower engine block. It is very close in appearance and construction to an accessary belt, with the exception that it is cogged.
Because of its material construction, the timing belt should be checked regularly, and replaced at least every 60000 miles (9661 km).
Because the Tempo/Topaz 2.0L engine is a non-freewheeling type, i.e. one in which that if the timing belt breaks, the valves will contact the pistons, it is very important that the timing belt be changed according to schedule, and checked regularly.
REMOVAL & INSTALLATION
Front Timing Belt
- Remove both timing belt covers.
- Rotate the engine clockwise until the timing marks on the flywheel and front camshaft sprocket are aligned with their respective pointers.
- Loosen the tensioner pulley lockbolt and slide the timing belt off the water pump and camshaft sprockets.
- With the flywheel timing mark at Top Dead Center (TDC), and the camshaft aligned with it's respective timing mark, install the front timing belt.
- Position and tighten the belt tensioner. Adjust until the tension is 33-44 ft. lbs. (147-196 Nm) using tensioner tool 021-00028 or equivalent. Once correct tension has bee reached, tighten lockbolt to 23-34 ft. lbs. (32-47 Nm).
- Rotate the engine clockwise 2 revolution and make sure the respective marks on the flywheel and camshaft sprocket are correct. Adjust if necessary.
- Install and secure both timing belt covers.
- Remove the rear timing belt cover according to the earlier procedure.
- Remove the flywheel timing mark cover from the clutch housing.
- Rotate the crankshaft until the flywheel timing mark is at Top Dead Center (TDC) on No. 1 cylinder.
- Check that the injection pump and camshaft sprocket are correctly aligned with their respective timing marks.
- Loosen tensioner locknut and with a flat prytool inserted into the slot, rotate the tensioner clockwise to relieve belt tension. When the tension is loose enough, remove the timing belt.
- Position the timing belt taking care not to alter the crank, injection pump or cam from their timing marks.
- With everything properly aligned, begin to increase the tension on the timing belt using a prytool.
- Once the timing belt is tensioned, rotate the engine 2 revolutions and check the timing marks on the flywheel and camshaft sprocket. Adjust if necessary.
- Install timing belt cover and secure with the retaining bolts.
