Thanks Matt, I'll look into those packings on the shaft , coupling side but still can't figure out what is going on at the other end of the pump housing, why coolant would be coming out there past the grease. I'm thinking of taking that front casting piece off, which I had done a few years ago to check that the impeller wasn't loose or rotted away, and can't remember if the shaft continues through the impeller and what type of seal is on the short end of the shaft to keep coolant from getting to the grease. Thank You Again!
Hello All, I am new to this forum as of Tuesday and thankful of all the information I have gained so far. I was nearing my wits end when I came across Matt's thread. As it turns out, we have the same car with the same problem I think. Before I drained the coolant for the third time I noticed a leak coming from the zerk fitting under the brass cap (pictured) in the front of the water pump. Does anyone know why coolant would be coming out of that grease fitting? I am considering going down the engine rust build up rabbit hole, but want to fill it one more time and run it and really shoot some block and radiator temps. to try to get a better idea what is going on, but I would like to address this leak while its empty. Thanks for any help it will be greatly apricated.
