You should be able to see it once you remove the lower radiator hose and then remove the flange from water pump. Removal and installation instructions are below. REMOVAL: Disconnect the negative battery cable. Drain the coolant. Remove the air intake duct. Disconnect the radiator hose Remove the thermostat housing. Remove the thermostat. Clean all sealing surfaces. Typical thermostat and housing.

Sure. Water pump is on the right side of the engine at the top. I believe it's on a separate belt. REMOVAL: Drain the coolant. Remove or disconnect the following: Negative battery cable Upper fill panel, if equipped AIR injection control valve, if equipped Air cleaner Oil level indicator tube nut, if necessary Water pump belt cover Water pump drive belt Lower radiator hose Thermostat bypass hose from the coolant inlet housing Water pump cover Remove the water pump by rotating it clockwise using special Tool J 38816-1A (water pump remover/installer).

INSTALLATION: Install the water pump with a new O-ring, by turning it counterclockwise using the special tool, until it stops. Torque the water pump to 73 ft. lbs. (100 Nm). Install or connect the following: Water pump cover. Torque the bolts to 89 inch lbs. (10 Nm). Lower radiator hose Thermostat bypass hose to the coolant inlet housing Water pump drive belt Water pump belt cover Oil level indicator tube nut, if necessary Air cleaner AIR injection control valve, if equipped Upper fill panel, if equipped Negative battery cable Refill and bleed the cooling system. Run the engine and check for leaks. Hope this helped. Thanks for using 2carpros.com!
