Water pump

[mac101]

I rebuilt my water pump and installed it using the new bolts that are machined to look like the original studs and nuts, doing this I didn’t have to pull the radiator. I have a leak coming from the top left bolt. These studs are threaded all the way to the nut. Is it possible the leak is around the threads?

Yes , there a couple of through holes in the head that will leak, drain the coolant remove the look alike studs and seal the threads that go into the head, refill with coolant

The upper left hole goes into the water jacket...like B H said remove that bolt and seal it...problem solved...
