Do you meant the front engine mount? I don't understand what the mounting block for the water pump would be.

If the water pump seal is leaking, the coolant will usually drip or seep down the underside of the pump and it might also drip on the engine mount. Tightening the packing may stop a water pump seal leak. Usually, 1/4 to 1/2 turn of the packing nut is enough. The steel plate on the back of the water pump can corrode and develop a leak.

*** It's also possible for coolant to seep out at one or more of the water pump to block bolts. Some of these bolt holes go through to the water jacket. Draining the coolant, removing the bolts one at a time, and blowing out the bolt holes, then putting sealer on the threads may stop the leak. ALSO!!: Some or all of the water pump bolts are supposed to have copper washers on them, not steel washers or lock washers. The copper washers are meant to prevent any possibility of coolant seeping along the bolts and leaking out.
