Engine Help with coolant leak.

[Mindseye007]

I'll bet you the gasket on back of wp went bad, or bolt on back( I belive 5/8" ) was loose.I ground down a open end wrench just for that.

How does the bolt get loose?

An inexpensive wp from parts store with a life time warranty or get one from Rockauto, mine was on my car for 40k miles, no need to spend a bunch of money on one but it's your money

its usually the gasket that goes , but the bolt can backout some by heat cycle/vibration,murrfys law.
the blue waterpump rtv works best i found. and a oreillys pump works great in the nevada desert.

Unless it’s dropped before installation, this is generally a safer buy than bulk rebuilt electrical parts.
I am interested in rebuilding my own pump next time. If you have a press and a solid core, it looks easy enough.
