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.
