Disconnect the cable from the negative battery terminal. Raise the vehicle and support it securely on jackstands. Remove the under-vehicle splash shield. Drain the cooling system. If the coolant is relatively new and in good condition, save it and reuse it. Once the coolant has drained, lower the vehicle. Remove the drivebelt. Remove the air filter housing and air intake duct/resonator. For V6 engines, use a pin spanner or strap wrench to hold the water pump pulley from turning, and remove the pulley mounting bolts and pulley. Remove the bolts attaching the water pump to the timing chain cover and remove the pump from the engine. If the water pump is stuck, gently tap it with a soft-faced hammer to break the seal. Clean the bolt threads and the threaded holes in the engine and remove all corrosion and sealant. Remove all traces of old gasket material from the sealing surfaces. For V8 engines, remove the engine cover. On non-supercharged models, remove the drivebelt tensioner and the idler pulley mounting bolt and pulley. On supercharged models, remove the supercharger drivebelt and tensioner, then remove the tensioner bracket bolts and bracket. Disconnect and remove the hoses to the water pump. Unbolt and remove the water pump from the front of the engine. It may be necessary to tap the pump with a soft-face hammer to break the gasket seal. To install, remove the gaskets from the engine, then compare the new pump and replacement gaskets to the old ones to make sure that they're identical. Apply a thin film of RTV sealant to hold the new gasket in place during installation. O-rings should be coated with clean coolant. Make sure the gasket is correctly positioned on the water pump and the mating surfaces are clean and free of old gasket material. Carefully mate the pump to the water pump housing. On V6 models, install the bolts and, following the recommended sequence, tighten the bolts to the torque. On V8 models, install the water pump bolts and tighten them, a little at a time, to the torque. The remainder of installation is the reverse of removal. Refill the cooling system. Operate the engine to check for leaks.
