- CAUTION:
- To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator.
Remove the radiator cap.

Remove the service hole cover from the engine under cover No. 1.
Install a vinyl hose onto the drain on the radiator side.
Fix the vinyl hose with tape.

Loosen the 3 drain plugs on the engine and radiator, and drain the coolant.
Drain the coolant from the reservoir tank.
Tighten the 3 drain plugs.
- Torque:
- 13 N*m{130 kgf*cm, 9 ft.*lbf} for the engine
Remove the vinyl hose from the radiator.
Remove the 2 nuts and throttle body cover sub-assembly.
Remove the 11 clips and radiator support seal upper.

Loosen the belt tension by turning the belt tensioner counterclockwise, and then remove the fan and generator V belt.
- HINT:
- The pulley bolt for the belt tensioner has left-hand thread.

Unfasten each clip and the 2 hose clamps, and then separate the 2 oil cooler hoses from the fan shroud.
Remove the 3 bolts and separate the fan shroud from the radiator.
Remove the 4 nuts and separate the fan with fluid coupling from the engine.
Remove the fan shroud and fan with fluid coupling together from the vehicle.
Remove the fan pulley.

Disconnect the vacuum hose.
Remove the nut, 2 bolts and vane pump assembly.
- HINT:
- Hang up the hoses instead of detaching.

Disconnect the generator connector.
Remove the terminal cap and nut, and disconnect the generator wire.
Disconnect the alternator wire clamp from the cord clip on the generator.
Remove the bolt, 2 nuts and generator.

Disconnect the compressor connector.
Remove the nut, 3 bolts, compressor stay and compressor.
- HINT:
- Hang up the hoses instead of detaching.

Remove the pulley bolt, cover plate and idler pulley.
Disconnect the 3 hoses.
Remove the bolt, nut and oil cooler pipe.

Remove the grommet and separate the cam position sensor connector from the No. 3 timing belt cover sub-assembly LH.
Remove the 4 bolts and No. 3 timing belt cover sub-assembly LH.
Remove the nut, 3 bolts and No. 2 timing belt cover.
Remove the 2 bolts and No. 2 timing belt cover sub-assembly.
Remove the bolt, 2 nuts and V-ribbed belt tensioner.
Remove the 2 nuts, 2 bolts and fan bracket sub-assembly.

Using SST, remove the pulley bolt.

Remove the 4 bolts and timing belt cover.

Remove the No. 1 crankshaft position sensor plate.

If reusing the timing belt, check the installation marks on the timing belt.
Check that there are 3 installation marks on the timing belt by turning the crankshaft as shown in the illustration.
If the installation marks have disappeared, put a new installation mark on the timing belt before removing each part.

Set the No. 1 cylinder to approx. 50° BTDC/compression.
Using the crankshaft damper bolt, turn the crankshaft to align the timing marks of the crankshaft timing pulley and oil pump body.

Check that the timing marks of the camshaft timing pulleys and timing belt plates are aligned.
If not, turn the crankshaft 1 complete revolution (360°).
Using the crankshaft damper bolt, turn the crankshaft counterclockwise by approx. 50°.
- NOTICE:
- If the timing belt is disengaged, having the crankshaft pulley at a wrong angle can cause the piston head and valve head to come into contact with each other when removing the camshaft timing pulley and camshaft, causing damage. So always set the crankshaft pulley at the correct angle.

Alternately loosen the 2 bolts, then remove the bolts, the chain tensioner and dust boot.

Using a SST, loosen the tension between the camshaft timing pulley (RH bank) and crankshaft timing pulley by turning the camshaft timing pulley (RH bank) counterclockwise slightly.
