Q: How to Replace the Water Pump on My Chrysler 200?
A: Disconnect the negative battery cable from the remote ground terminal or battery. Set the parking brake, raise the front of the vehicle and support it securely on jackstands. Drain the cooling system. For the 2.4L four cylinder engine, remove the accessory drivebelt, accessory drivebelt splash shield, water pump pulley bolts, water pump pulley, and water pump mounting bolts. For the 2.7L V6 engine, remove the radiator fan assembly, accessory drivebelt, timing chain and guides, and water pump bolts. For the 3.5L V6 engine, remove the timing belt and water pump mounting bolts. For the 3.6L V6 engine, remove the Coolant Reservoir tank, right side engine mount, engine mount block from the water pump, lower engine cover, right front wheel, inner fender splash shield, drivebelt, idler pulley, air conditioning compressor, bypass and lower radiator hoses, and water pump mounting bolts. Clean the bolt threads and threaded holes in the timing case cover. 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 a thin coat of RTV sealant to the new water pump O-ring and position it in the groove on the back of the water pump. Install a new seal, then carefully mate the pump to the engine. Install the water pump mounting bolts and tighten them to the torque. The remainder of installation is the reverse of removal. Refill and bleed the cooling system. Run the engine and check for leaks and proper operation.
