How to replace a water pump on Cadillac CTS?

However, you need to drain the cooling system and remove the timing belt cover in order to change the water pump. Next, it is recommended to undo the water pump bolts (using catch basin to collect the escaping coolant), and extract the water pump and seal extracting it; be warned not to reuse the seal. If the cover seal of the pump on the rad seal is leaking, then it should not leak; otherwise, it will necessitate a new pump. Must remember to inspect the mating surfaces of the water pump. Coat the seal ring of the water pump with silicone grease, GM P/N 12345579 (Canadian P/N 1974984), or equivalent, and make sure the O-ring seal is seated properly before installing on the water pump.
