A failure in the water pump can cause engine damage. To check for leaks, use a flashlight to find the weep hole on the pump from underneath. Shaft wear can be felt if the water pump pulley is rocked up and down. It is possible for a water pump to be bad, even if it doesn't howl or leak water; the only way to check is to remove the pump for examination.

Disconnect the cable(s) from the negative battery terminal(s). Drain the cooling system. Remove the drivebelt and air filter housing. Disconnect the heater and radiator hoses. Remove the idler pulley and water pump mounting bolts. Detach the fan assembly and lower radiator hose. Clean the bolt threads and engine surfaces. Compare the new pump to the old one. Remove all traces of old gasket material. Clean the engine and water pump mating surfaces. Position the O-ring/gasket on the pump. Attach the pump and O-ring/gasket to the engine. Tighten the bolts in a criss-cross pattern. Turn the water pump by hand. Reinstall all parts removed. Refill the cooling system. Run the engine and check for leaks.

Start by disconnecting the battery's negative terminal and draining the cooling system. Remove the coolant reservoir/windshield washer reservoir assembly on V6 models, as well as the cooling fan(s) and shroud. Take off the drivebelts and water pump pulley, and on 2.4L four-cylinder engines, remove the timing belt, timing belt idler pulley, camshaft sprockets, and rear timing belt cover. For 3.7L V6 engines, detach the lower radiator hose from the pump. On 4.0L engines, remove the air filter housing and the right engine mount through-bolt. Use an engine hoist to raise the engine slightly and secure it in place with a jack.

A failure in the water pump can cause serious engine damage due to overheating.

Attach the pump and O-ring/gasket to the engine.

The only way to check for corroded fins on the water pump impeller is to remove the pump for examination.

Clean the engine and water pump mating surfaces.

There are several ways to check the operation of the water pump while it's installed on the engine. If the pump is defective, it should be replaced with a new or rebuilt unit. Water pumps are equipped with weep or vent holes. If a failure occurs in the pump seal, coolant will leak from the hole. In most cases you'll need a flashlight to find the hole on the water pump from underneath to check for leaks. If the water pump shaft bearings fail there may be a howling sound at the front of the engine while it's running. Shaft wear can be felt if the water pump pulley is rocked up and down.
