NOTE: Always carefully inspect the Water Pump when replacing the Timing Belt, as the pump is timing belt driven.

Fig. 5 Accessories & mounting brackets removal & installation:

1. Disconnect battery ground cable.

Air Conditioning Belt:

Alternator/Power Steering Belt:

2. Remove accessory drive belts.
a Loosen adjusting lock nut on A/C belt adjuster, Turn adjusting jack screw counterclockwise to reduce belt tension.
b Install breaker bar into 1/2 square opening in tensioner on Alternator/Power Steering belt. Rotate tensioner counterclockwise to remove belt.

3. Remove A/C compressor, alternator, power steering pump, tensioners and mounting brackets as shown in Fig. 5, and set aside.

Right Inner Splash Shield - Typical:

4. Raise and support vehicle, then remove right inner splash shield.

Fig. 6 Crankshaft pulley removal:

5. Remove crankshaft drive pulleys and torsional damper, Fig. 6, then lower vehicle and position a suitable jack under engine.

Fig. 7 Engine mount removal - Typical:

6. Remove engine mount insulator from engine mount bracket, raise engine slightly, then remove engine mount bracket as shown in Fig. 7.

Fig. 8 Timing belt cover removal:

7. Remove timing belt covers as shown in Fig. 8.

9. Loosen timing belt tensioner, Fig. 9, then remove timing belt.
10. Remove crankshaft sprocket flange, if necessary.
11. Remove camshaft sprocket attaching bolts, then the sprockets, if necessary.

Camshaft Sprockets:

12. Install camshaft sprockets, then using camshaft sprocket holder tool MB990775, torque bolts to 73 ft. lbs.

Fig. 10 Positioning timing belt tensioner:

13. Install timing belt tensioner and spring. Rotate tensioner counterclockwise, Fig. 10, then temporarily tighten bolt.
14. Install timing belt on crankshaft sprocket first, while keeping belt tight on tension side, then position belt over front camshaft sprocket, Fig. 9.
15. Then, install belt on water pump pulley and rear camshaft sprocket and finally on the timing belt tensioner, Fig. 9.
16. Rotate front camshaft sprocket in opposite direction and check that all timing marks align, Fig. 9.
17. Install crankshaft sprocket flange, then loosen tensioner bolt to allow spring to tension belt. Rotate crankshaft two complete revolutions, in direction of normal rotation and check timing marks.
