The first step in water pump service and repair is to disconnect the battery's negative lead and lift the vehicle onto a jack. Eliminate the right interior splash shield, disconnect the belts and empty the cooling system. Place something underneath the engine and take out the right
Engine Mount, next remove the right engine mount bracket. After that, take out the
Timing Belt and timing belt idler pulley. Grab tool C-4687 and adapter C-4687-1, hold the camshaft sprocket with them while you remove the bolt and then remove both cam sprockets and the timing belt rear cover. Go on to remove the generator and bracket from the engine, then detach the water pump by unscrewing the equaling screws. Whenever required, make sure the surfaces where gaskets sit are clean. Check the water pump body for splits, cracks in the shaft seal that could be leaking coolant, bearings that move in a rough way, the impeller touching the pump body or engine and damage to the impeller or sprocket. If something is wrong with the water pump body assembly, replace it. Make sure to slide the new O-ring gasket into the water pump body's groove and check its fit, so it doesn't let coolant leak. Assemble the pump to the block and tighten the screws to a torque of 12 Nm (105 inch lbs.), then pressurize the cooling system to 103.4 kPa (15 psi) and look for any leaks at the water pump shaft seal and O-ring. Turn the pump by hand to make sure it rotates freely and then place the timing belt cover in the rear. With the special tool, rotate each sprocket and tighten the fasteners to 101 Nm (75 ft. lbs.). Put the timing belt idler pulley in place and tighten its mounting bolt to 61 Nm (45 ft. lbs.), after that install the timing belt. Mount the bracket and generator to the generator mount plate and then screw in the right engine mount bracket before connecting the engine. Refill the cooling system, fix the accessory
Drive Belts, let the car wait with its bottom off and reconnect the battery cable.
