Disconnection of all the negative battery cable and draining the cooling system is necessary to remove the water pump in the 1.5L, 1.6L, and 1.8L engines (except K8). The second step is to remove
Timing Belt covers, timing belt, unconnect coolant inlet pipe, and gasket. Take out the timing belt idler pulleys to the water pump then remove the water pump mounting bolts to remove the water pump. Installation To install, clean all mating surfaces of the gasket, replace the rubber seal on the water pump and use a new gasket to install the water pump to the engine and tighten the bolts to 14-18 ft. lbs. and the water pump bolt to the alternator bracket to 28-38 ft. lbs. Lastly, fit the timing belt and covers, fill and bleed the cooling system, re-connect the negative battery cable, start the engine and check the leaks. In 2.0L engines, the procedure will start by the same way as in case of 1.5L engines wherein it will be necessary to disconnect the negative battery cable and empty the cooling system, then take off the timing belt and the power steering oil pump adjuster and then the five water pump mounting bolts to take away the water pump. Installation entails cleaning gasket surfaces, fitting a new gasket on the water pump and tightening the mounting bolts to 14-18 ft. lbs. Reconnect the power steering oil pump adjuster, torque the mounting bolts to 12-16 ft. lbs., installations of the timing belt, reconnect negative battery cable, fill and bleed the cooling system, and look after starring the engine. In engines with 1.8L (K8) and 2.5L, beginning with removal of the negative battery cable and the draining of the cooling system, followed by dismantling the timing belt and the No.3 engine mount bracket, and placing a drain pan beneath the water pump and then removes the five mounting bolts. To install, clean mating surfaces and assemble a new rubber seal on the water pump and torque the bolts to 14-18 ft. lbs. Reinstall the engine mount bracket and tighten the bolt to 32-44 ft. lbs. and install the timing belt, reconnect the negative battery cable, fill and bleed the cooling system and inspect all leaks after the engine has started. With the 2.3L engine, the first step would be to disconnect the negative battery cable and drain the cooling system followed by the removal of timing belt covers and timing belt, and the process would be to use a pulley removal tool to hold the water pump pulley as the bolts are removed. Prepare a drain pan beneath the water pump, remove the mounting bolts then extract the water pump. To install, clean the mating surfaces, replace a new O-ring on the water pump and tighten the bolt to 18 ft.lb., then reattach the water pump pulley, holding it with the tool as tightening the bolts to 88inch lbs., before installing the timing belt and covers, reconnect the negative battery cable, emptied and bled the cooling system and checked for leakage after starting the engine.
