Disconnect the cable from the negative battery terminal. On 2015 and later models with an Intelligent Battery Sensor (IBS), disconnect the JBS connector first before disconnecting the negative battery cable. Drain the cooling system and remove the engine cooling fan assembly. Remove the drivebelt. For 2.7L V6 engines, remove the timing chain and guides. For 3.SL V6 engines, remove the timing belt. For 3.6L V6 engines, remove the air filter housing and detach the heater hose and lower radiator hose from the water pump. Remove the idler pulley for the drivebelt. For V8 engines, remove the air filter housing and thermostat. Detach the radiator hose from the water pump. Remove the idler pulley and, on later models, the tensioner. On 2011 and later models, remove the heater tube mounting bolt. Remove the bolts and detach the water pump from the engine. Clean the bolt threads and threaded holes. Compare the new pump to the old one. Remove all traces of old gasket material or the O-ring seal. Clean the engine and water pump mating surfaces. Apply RTV sealant to the new water pump O-ring or gasket. Attach the pump and O-ring/gasket to the engine and tighten the bolts. Connect the hoses to the water pump and reinstall all removed parts. Refill the cooling system, run the engine, and check for leaks.

Remove the engine cooling fan assembly.

On the 5.7L V8 engine, the water pump is externally mounted and weep holes may be visible. Using a flashlight, look for traces of coolant residue or dried coolant tracks around the weep hole(s). If the seal has leaked, it should be very apparent.
