Water Pump Installation

1. Install water pump

Install a new gasket and the water pump with the 4 bolts and 2 nuts.

Torque: 8 N.m (80 kgf.cm, 69 In.lbf)

NOTICE: Do not get oil on the gasket.

2. Install No.3 timing belt cover.
(a) Check that the timing belt cover gaskets have no cracks or peeling, etc.

If the gaskets do have cracks or peeling, etc., replace them using the following steps.

(1) Using a screwdriver and gasket scraper, remove all the old gasket material.
(2) Thoroughly clean all components to remove all the loose material.
(3) Remove the backing paper from a new gasket and install the gasket evenly to the part of the belt cover shaded black in the illustration.

NOTICE: When joining gaskets, do not leave a gap between them. Cut off any excess gasket.

(4) After installing the gasket, press down on it so that the adhesive firmly sticks to the belt cover.

(b) Install new gaskets to the No.3 belt cover.

3. Connect engine wire

Connect the engine wire with the 3 clamps.

4. Install No.2 idler pulley
(a) Install the idler pulley with the bolt.

Torque: 43 N.m (440 kgf.cm. 32 ft.lbf)

(b) Check that the idler pulley moves smoothly.

5. Install RH camshaft timing pulley
(a) Install the timing pulley, facing the flange side outward.
(b) Align the knock pin hole of the camshaft with the knock pin groove of the timing pulley as shown.

(c) Using SST, install and torque the bolt. SST 09249-63010, 09960-10010 (09962-01000)

Torque: 88 N.m (900 kgf.cm. 65 ft.lbf)

HINT: Use a torque wrench with a fulcrum length of 340 mm (13.39 in.)

6. Install LH camshaft timing pulley
(a) Install the timing pulley, facing the flange side inward.
(b) Align the knock pin hole of the camshaft with the knock pin groove of the timing pulley as shown.

(c) Using SST, install and torque the bolt. SST 09960-10010 (09962-01000)

Torque: 125 N.m (1,300 kgf.cm, 94 ft.lbf)

7. Install timing belt
8. Fill with engine coolant

Capacity: 8.7 liters (9.2 US qts, 7.7 Imp. qts)

9. Connect negative (-) terminal cable to battery
10. Start engine and check for leaks
11. Recheck engine coolant level
