How to replace the water pump (LA3, LY9) on 2004 Cadillac CTS?

The first step to replace the water pump (LA3, LY9) includes draining the cooling system and taking off the timing belt cover. Use a catch basin to capture coolant while loosening the water pump bolts. You should remove the water pump along with its seal before discarding the seal while cleaning the mating surfaces and inspecting the pump. Silicone grease from GM P/N 12345579 (Canadian P/N 1974984 or equivalent) needs application on the water pump's seal ring before installing the O-ring seal properly before pump assembly. Utilize the Fastener Notice in Service Precautions while installing the water pump into the engine block then secure the water pump bolts by torquing them to 25 Nm(18 ft. lbs.). Reinstall the timing belt cover then refill the cooling system as the final installation step.
