I have a 92 Ford Mustang 5.0 V8 5 Speed and it has about 150,000 and
I am going to replace my car's water pump for the secodn time under my ownership. The first time I replaced it at about 80,000 and about 4 years ago. Is that too often or about right?
Also, if the hoses are good, the clamps are tight as can be and the radiator is good as new and so is the water pump and I still see drops of coolant here and there, where can the leak be coming from?
thanks.

i would get a small mirror and look underneath the water pump, shine a light to it until you can see the weep hole on the water pump. do a pressure test on the radiator and see if it's the water pump.

I looked at the weephole and saw a constant drip coming from there and from when I posted the initial question to when it was answered I drove my car and the leak has grown to a steady drip. I assume it is the water pump but I will get the radiator checked out too.

Unfortunately the time frame you mention is probably just about right, sometimes we get lucky, sometimes not...

Yeah, I thought about it and it seemed as if I replaced it more recent than that but in retrospect I guess it sounds right.
What else should I replace or check out while swapping out the water pump?

Suggested Repair

A steady drip from the water pump weep hole indicates the pump is failing and should be replaced. Pressure-test the radiator and cooling system, flush the system while the pump is out, and consider installing a new thermostat.

Conversation Summary

The owner of a 1992 Ford Mustang 5.0 reported a recurring coolant leak and asked whether a second water pump replacement around 150,000 miles was too soon, and where else coolant could leak if the hoses, clamps, radiator, and pump appeared good. An expert advised inspecting the pump weep hole with a mirror and light and pressure-testing the radiator. The owner then confirmed a steady drip from the weep hole. Experts said the replacement interval was about normal and recommended flushing the cooling system and considering a new thermostat during the pump swap.
