Coolant Leak

[nobbyv]

My '95 4.0 is no longer my daily driver, but when I made I Home Depot run the other day I pulled back into the driveway to coolant pissing out of the engine bay onto the ground. It only leaks when running, otherwise dry as a bone. I can't figure out exactly what it is I'm looking at here or where the leak is coming from. Not even sure what to search on to find out how to fix it. Can anyone tell what the most likely place this leak is coming from is? Thanks!

Looks like maybe its flowing down to what you see in this pic from the waterpump area. I assume that has failed.

Check for leaks in the following areas;
Thermostat housing - Only sealed by an o-ring that really does not qualify as being an o-ring. Mine leaked a little and I thought it was my water pump at gasket at first. It was the crappy o-ring on the thermostat I installed after a rebuild. Resealed the o-rings bearing surface with some rtv silicone..... fixed.

Hose Clamps - One of mine lost a little of it holding strength after removing it a couple times. Started a pretty good 2 second drip on the bottom fitting on my radiator. Replaced clamp and problem fixed.

- Freeze Plugs on the block and heads
- Lower intake gasket where it meets the heads
- Water pump gasket and bearing
- Replace any dry rotted or crunchy feeling (when squeezed) hoses

Thats all I can think of that would be located in the vicinity of that leak. Hope that helps a bit.
