Small coolant leak.

[Sean]

And, I cannot, for the love of my, figure out where it's stemming from! It looks to be coming somewhere from the thermostat housing, but everything is tightened down! Both sensors, all hoses - the one thing I haven't tightened are the bolts holding the thermostat in. Maybe I'll give that a shot.

Any idea on how to figure out where all this shit is comin from? I know it's still leaking form SOMEWHERE - it's just a VERY small leak!

The nipple that the throttle body hose goes into on the bottom of the housing is a major cause of leaks. They only fix short of a new housing is to remove the nipple, clean it up and jbweld it in there good.

It doesn't FEEL like it's coming from there. I had the whole housing out, powdercoated and everything, before I put it back on my car. I didn't notice any problamatic spots whatsoever. The worst part is, it's REALLY hard to tell. I KNOW it's leaking, cause there's fresh coolant all over EVERYTHING. It sucks, cause my engine was so clean you could eat off of it less than a week ago. I just want this leak gone so I can clean my engine and drive around in a fluid-less engine for a while! lol

Maybe I need to run to a shop that has a pressure tester and have them take a quick look? Or can I get a pressure tester somewhere?

The interesting thing is that the gasket between my head and thermostat housing has a spot that looks wet while the car is running - almost like it's leaking out of that. But, I don't see fluid flowing out of it or anything. I'm thinking its wet BECAUSE of a leak - but again, I already fixed my tiny leaks on the top of the thermo housing. So - I'm really at a loss here!

Tightend the bleeder back down right? I forgot to do that after a t belt replacement. Didnt realize till the coolant light came on bout 100 miles later.

Oh yea, it's tight.

Did happen on my first startup though! So - yea, it happens. LOL
