To remove the water pump, start by disconnecting the negative battery cable and draining the cooling system. Depending on the engine type, you may need to loosen water pump pulley bolts or remove the drive belt. For four-cylinder models, remove the right front wheel, fender splash shield, and the water pump pulley. On 1.5L and 1.6L models, additional steps involve removing the air filter housing, turbocharger inlet pipe, drivebelt tensioner, timing belt, and disconnecting the electrical connector for the water pump clutch. Remove the water pump mounting bolts to take out the pump. For 2.0L, 2.3L, and 2.5L models, remove the bolts attaching the water pump to the engine block. In the case of the 2.7L engine, support the engine, remove the right engine mount and bracket, thermostat, water pump pulley bolts and pulley, disconnect the coolant hose, and remove the water pump mounting bolts. On 3.0L V6 models, removal is more intricate, involving the removal of the water pump drivebelt and using special tools to access all water pump bolts. You may also need to disconnect hoses and other components as specified for your engine. After removal, clean the gasket and O-ring surfaces on the pump and the housing. For installation, ensure the new water pump matches the old one and apply RTV sealant to hold the new gasket in place. O-rings should be coated with clean coolant. Install the water pump bolts and tighten them, and on 3.0L V6 engines, use special tools to reinstall the water pump pulley to the camshaft. The remainder of the installation process involves reversing the removal steps, ensuring to refill and bleed the cooling system and checking for leaks. For 2.7L V6 models, clean the mating surface on the front cover before installation and lubricate the grommet and O-ring gasket with clean antifreeze. Verify the dowel pins are in place, install the water pump, tighten the bolts evenly, and follow the remaining steps in reverse order. Finally, operate the engine to check for any leaks.
