Parts shown when removing the belt (3.5L)
1, 4. Cover; 2. Crankshaft speed sensor connector; 3. Pulley; 5. Belt; 6. Automatic tensioning device; 7. Tensioner roller; 8. Lever
Removal
1. Disconnect the battery from ground.
2. Drain the liquid.
3. Disconnect the radiator hose and remove the upper fan shroud.
4. Remove the fan with the clutch.
5. Remove all accessory belts.
6. Remove the fan pulley from the cooling pump.
7. Remove the power steering pump and bracket. Move the pump to the side without disconnecting it from the line.
8. Remove the tensioner roller bracket.
9. Remove the air conditioning compressor. Move the unit to the side without disconnecting it from the line and secure it. Remove the compressor bracket.
10. Remove the fan bracket.
11. Remove the upper belt covers and gaskets. On a 3.5L engine, remove the crankshaft speed sensor.
12. Remove the lower belt cover.
13. Set the piston of the 1st cylinder to TDC of the compression stroke. From this point on, rotation of the crankshaft is not allowed.
14. Loosen the pulley bolt, holding the crankshaft with a special key and remove the pulley.
15. Loosen the tensioner bolts and carefully remove the timing belt, marking the direction of rotation.
Installing a Belt on a 3.0L Engine
1. Check the condition of the belt, replace it if any defects are found.
2. Check the condition of the tensioner roller and sprocket teeth.
3. Install the tensioner, turn it counterclockwise and secure it with bolts.
4. Check the alignment of the marks on the sprockets and put on the belt, following the arrow. The belt must be tensioned between the crankshaft and left camshaft sprockets. When installing, apply slight pressure on the left camshaft sprocket counterclockwise. If the belt is tight, the marks should match.
5. Install the flange onto the crankshaft sprocket.
6. Loosen the tensioner bolt so that the roller rests against the belt.
7. Smoothly, without jerking, turn the crankshaft 2 turns clockwise and check the alignment of the marks.
8. Tighten the tensioner bolt to 25 Nm.
9. Install all parts in reverse order. Replace damaged cover gaskets by placing them in the cover using 3M EC 870 adhesive. Tighten the cover bolts to 11 N·m.
Installing a Belt on a 3.5L Engine
1. Check the condition of the belt, replace it if any defects are found.
2. Check the condition of the tensioner roller and sprocket teeth.
3. Clamp the tensioner in a vice and secure it by inserting a 1.4 mm diameter wire into the holes. Install the tensioner and tighten the bolt to 24 N·m.
4. Install the crankshaft pulley and turn the crankshaft sprocket so that it moves 3 teeth clockwise.
5. Align the marks on the camshaft sprockets of the left head.
6. Align the marks on the camshaft sprockets of the right head and secure with a key to prevent turning.
7. Make sure that the camshaft marks on the right cylinder head are aligned and secure the belt with 2 clamps.
8. Place the belt on the cooling pump pulley.

9. Make sure that the camshaft marks on the left cylinder head are aligned and secure the belt with 2 clamps.
10. Place the belt on the idler roller.
11. Align the marks on the crankshaft sprocket and turn the crankshaft 1 tooth counterclockwise.
12. Place the belt on the crankshaft sprocket and on the tensioner roller.
13. Position the tensioner pulley so that the pin hole faces upward. Press the roller and tighten the bolt.
14. Align the marks on the crankshaft sprocket.
15. Check that all marks are aligned.
16. Turn the crankshaft 1/4 turn counterclockwise, then turn it clockwise and align the marks.
17. Loosen the tensioner bolt (2).
Using a special key, turn the tensioner to a torque of 9.4 N·m, tensioning the belt, and at the same time tighten the tensioner central bolt to the specified torque. When tightening the tensioner bolt, the roller should not rotate (1. Pin hole; 3. Tensioner roller).
18. Remove the wire from the tensioner and make sure the pin can be easily removed.
19. Turn the crankshaft 2 revolutions and leave it in this position for 5 minutes.
Check the freedom of movement of the pin in the tensioner hole. If the pin enters with a little effort, then check the protrusion of the tensioner rod (A), which should be 3.8–4.5 mm. Otherwise, repeat the procedure for putting on and adjusting the belt tension.
20. Check that all marks on the sprockets are aligned.
21. Install all parts in reverse order. Replace damaged cover gaskets by installing them in the cover using 3M EC 870 adhesive. Tighten the cover bolts to 11 N·m. After starting the engine, listen for noise from the belt. If unusual noises are heard, stop the engine and check the belt installation and tension. When finished, adjust the drive belts of the attachments.
