Jeep Liberty CRD Timing Belt Replacement

Procedure (2.8l diesel)

1. Remove cooling fan and shroud. The fan assembly is best

removed with a very large crescent wrench on the nut just behind

the fan viscous coupling. Then hit the wrench in a counter

clockwise direction with a small sledgehammer. It may help to

spray with penetrating oil. Worst case, wedge something behindthe fan drive pulley to keep it from rotating and then use the

sledge method.

2. Remove accessory drive belt.

3. Remove both idler pulley (right hand thread, 16 mm) (a), power

steering pump (3 bolts that you get to by rotating the pulley, 10

mm) (b), accessory belt tensioner (c), cooling fan pulley and

bracket( 4-13 mm bolts) (d), crankshaft pulley/damper (4-10mm

bolts, you may need to hold the pulley by the 21 mm center bolt)(e), and alternator (2-13 mm bolts on the front and 1-15 mm on

the back side-note you will have to loosen the 2-13 mm bolts for

the bracket that holds the alternator to the cylinder head) (f) .

4. Remove the front timing cover (7mm bolt x 17)

5. Remove both plugs in the camshaft cover (one on intake side

behind alternator placement, one on exhaust side behind

thermostat area). Remove the plugs with a 5mm hex.

6. Rotate the engine clockwise only with a 21mm socket on thefront of the crankshaft until a 6mm hex key engages the hole in

the flexplate/flywheel.

7. Inspect the two openings in the camshaft cover to see if the holes

in the camshafts align. If so, install the two pins into the

respective camshaft. If not, rotate the engine 360 degrees at the

crankshaft and re-inspect.

8. Loosen the timing belt tensioner and rotate counterclockwise by

hand until slack is sufficient to remove the belt from the pulley.

Remove the old timing belt; discard when the refitting operating

is completed successfully.

9. Loosen both camshaft pulleys by rotating the bolt (17mm)

counterclockwise. It is sufficient to have them loose; they do not

need to be removed.

10. Ensure that the high-pressure fuel pump pulley is oriented

properly (see picture) and fit the new belt to the engine. Starting

from the crankshaft pulley, remove the slack out of the belt by

using the camshaft gear locking tool to pull the tension across the

pulleys. Then torque the two camshaft pulley bolts to the

specified torque in service manual.

11. With the belt properly installed around the pulleys, tension the

timing belt with the pulley as shown in the picture. If the proper

handle isnt available, the pulley can be moved with two 3mm hex

keys. Rotate the tensioner until the proper gap on the pulley is

achieved. Tighten the center fixing bolt to 30N-m.

12. Remove the two camshaft pins and crankshaft pins and rotate the

engine 720 degrees and verify that the timing belt tensioner is

still in the proper orientation.

13. Reinstall the timing belt cover and all ancillary components.
