Mopar 5093911AA Water Pump

Remove the air conditioning compressor mounting bolts and the accessory drivebelt bracket and timing belt. Remove the water pump bolts and detach it from the engine. Clean the bolt threads and threaded holes, and compare the new pump to the old one to ensure they're identical. Remove any old gasket material and clean the engine and new water pump mating surfaces. Apply ATV sealant to the new water pump O-ring for four-cylinder engines or to the gasket mating surface for 3.7L V6 engines. Attach the pump and O-ring/gasket to the engine and tighten the bolts in a criss-cross pattern. For 4.0L engines, install a new O-ring seal in the water pump groove and carefully mate the pump to the engine. Install the water pump mounting bolts and tighten them. Reinstall all parts that were removed for access to the pump, refill the cooling system, and check for leaks.

Don't mistake drivebelt slippage, which causes a squealing sound, for water pump bearing failure.
