Coolant Leak near firewall

I have a odd coolant leak. It is near the back of the engine, and by
the heater hoses. The link is actually coming from the engine, near
some odd metal part that attaches and rises above the engine. It has
two parts.

The coolant pours out, especially when the engine is revved. I have
checked the hoses and valve. All are perfect.


Are you familiar with this kind of leak. How easy is it to repair?
Thanks.

I'm not sure which odd metal part you are talking about. But if the
coolant is actually coming out of an odd metal part of the motor you
do have a problem. Please provide a picture or more precise
description.

 

Not having any idea what year/model/engine this is, I'd venture to
guess you need to have the odd metal part replaced. If it's where
the leak is coming from, checking the hoses and valve are pointless.

Depending upon the age of the hoses, you might want to go ahead and
replace them while you're having the odd metal part replaced.

I don't have a clear picture, but it sounds like you are describing the
coolant temperature sender used in some models to control the heater fan. If
so, it will have a connector for a pair of wires IIRC.

I haven't dealt with the fitting to the engine at that point; it sounds like
a wicked spot to work on. I've dealt with a similar fitting in an engine
that had been run with plain water in the coolant system for a while. The
fitting and mating surface were badly corroded and I never got it to stop
leaking altogether. The fitting had an O ring fitted into the inner surface,
and replacing and even gooping it up with form-a-gasket only reduced it to a
slow drip. I suspect you'd consider that an acceptable victory at this stage
:-(
