Default How can i tell if my water pump is broken.? please help.

i have a 66 inline 6. noticed i was leaking fluid. checked all the main radiator hoses everything seems fine. the leak is coming from underneath the fan pulley system so im assuming its the water pump. i dont know much about water pumps and was wondering if i might need a new one? what a decent price is? or if u can have it repaired?. appreciate all the help. thanks everyone =))

Not sure if you can find a place to rebuild it.Would be just as easy to replace it.

There is a small hole on the underside of the pump where the water will come from. I do not know of any one rebuilding waterpumps but you are better of getting a new one anyway. They cost 30 to 50 dollars.

It's broke, buy a new one. Does the fan shake/move back and forth by hand?

Buy a new one, not a rebuilt one. Its worth it not to break down on the road someplace.

Never, ever buy a rebuilt. I learned that lesson 30 years ago with a 390 ci motor. I went thru two rebuilts in a fairly short period of time. Once I figured it out, I never had to replace it again as long as I owned the vehicle. Buy the best new pump that you can determine.

No one would ever believe this story. I had broken down at the Colorado River in the middle of summer time. You know, 110-115 degrees and water was coming out of the hole in the water pump. I actually went through 3-yse, 3 rebuilt water pumps until I decided to buy a new one. While it wasn't a big deal to put 3 water pumps on because the car I was driving had no luxuries like power steering, A/C, etc, it was the heat. Lesson learned the hard way. That appears to be the way I learn things.
