You got to get it pluged into a diagnose computer to get it cleared this usually cost's more than replacing the belt. Your trooper is 1994 so best to take out the speedo and guages remove the bulb and keep a note of when its due the next one which is every 50,000 miles

Front seal replacement


Hi No Name, The most likely place of the leakage on your car is the front crankshaft oil seal. The oil pan (sump) is fitted with silicon from a tube as the gasket. It rarely leaks unless someone has broken the seal, which is difficult and usually needs a special tool for removal. To replace it you'll need to disconnect the battery, remove the PK (Serpentine) belt and the power steering pump belt and the front engine mounting (Front of the engine but fitted onto the side of the body) Next remove the crank shaft pulley, (a difficult part of the job, made easier if the starter motor is removed and a dog tooth tool is bolted into the most suitable starter motor attachment bolt holes, the dog tooth is used to lock the flywheel while removing the crankshaft bolt holding the pulley (which is torqued to 76 nm when re-fitting. Use a puller to remove the pulley from the crankshaft and then remove the ten mm bolts holding the two parts of the timing belt cover. Set the engine to T.D.C (Top Dead Center) and look for the match marks for re-timing the engine when refitting the timing belt. Once alignment has been achieved release the bolt holding the tensioner bearing and push it all the way open, releasing all tension from the timing belt and remove the timing belt. The oil seal can now be removed from its housing. Fit a replacement oil seal smearing a light coating of grease on the seal lip. Press evenly into place, making sure of an even flush fit. Replace the timing belt with a new belt, Re-align the belt so that the match marks align precisely to those on the gears by fitting and adjusting on the straight side of the belt. Once correctly fitted, gently release the tensioner bearing until it comes into full contact with the belt and hand tighten the fixing bolt and then loosen half one turn. Remove the dog tooth tool. Screw in the crankshaft pulley bolt and apply enough force to take up slack and tighten the tensioner. Remove the crankshaft bolt and then reassemble opposite to disassembly. Remember to refit the dog tooth for re-tightening the crankshaft bolt.

archaeology_67.jpg

Fig 3. Injection pump alignment marks - Diesel engine.

archaeology_68.jpg

Fig 4. Tensioiner Pulley Bolt Sequence - Diesel engine.

archaeology_69.jpg

Procedure - Timing Belt replacement.

1. Disconnect the negative battery cable. Drain the cooling system.

CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

2. Remove the timing belt cover. Remove the injection pump sprocket flange.

3. Using a prybar, remove the tension spring from the timing belt tensioner.

When removing the tension spring, avoid using excessive force for the spring may become distorted.

4. Remove the tensioner pulley bolt and the pulley.

5. Remove the timing belt and discard it.

To install:

6. Rotate the crankshaft to bring the No. 1 piston to TDC of the compression stroke.

7. Align the timing marks on the injection pump sprocket with the camshaft sprocket; the marks must be facing each other.

8. Using a new timing belt, install it in the following sequence: crankshaft sprocket, camshaft sprocket and the injection pump sprocket; the slack must be between the injection pump and camshaft sprockets.

9. Install the tension center and the tension pulley so the end of the tension center is fitted against both pins on the timing pulley housing.

10. Hand tighten the nut so the tension pulley can be rotated freely.

11. Install the tension spring and semi-tighten the pulley nut to 22-36 ft. lbs. (30-48 Nm).

12. Rotate the crankshaft 2 full turns clockwise to seat the belt and further turn the crankshaft 90° beyond TDC to settle the injection pump.

13. Loosen the tension pulley nut to take up the timing belt slack. Tighten the tension pulley nut to 79-94 ft. lbs. (108-128 Nm).

14. Install the injection pump sprocket flange; the hole in the outer circumference of the flange should be aligned with the triangular timing mark on the injection pump sprocket.

15. Rotate the crankshaft 2 full turns clockwise to bring the No. 1 piston to TDC of the compression stroke. Make sure the triangular timing mark on the timing sprocket is aligned with the hole in the flange, then, measure the timing belt tension; it should be 33-55 lbs.

16. Install the timing belt cover.

17. Connect the negative battery cable.
