You said that it does it AFTER it is up to 200^, but not before? Sounds as if there is (as you already know) a leak somewhere, but on the downside of the system. Check all the fittings on the top end ot he engine on that side. See if there is a leak. If it leaks that much, put the car in park and let her run for a while. That may help to flush out the location of the leak.

okay I just spent some time with a mirror and flashlight...

It looks like (as suggested) the bypass fitting on the lower manifold. The only reason coolant appears on the water pump at all is because it is leaking down from up there. It'* causing a pretty steady drip now when the engine is on and warmed up.

OK - two questions..

1. How long will this take to fix? It looks like if I just take off the alternator it will be pretty easy to get to. Am I right?

2. Is this thing going to blow out and spill coolant all over the road at any given time?

I just need to set aside the time to address it - like tomorrow... or next sunday? Thanks everyone for the responses already.

Thanks

It'* very simple to fix, take off the belt and the alternator it'* a pretty straight shot. My guess is that you'll break the fitting gettin it off, and if you're that unlucky you'll neet a good sized drill bit (or an easy-out) to get it out of the intake. The new part is made of BRASS (like GM should have done, cheap idiots) and costs like 5 bucks or so. I've done a dozen of these in the past few years. Really simple.

As I start reading the post...I know this one. Before the second thread I said...I'll put money on it!!!

Get that plastic piece out QUICK, mine let go on the highway and spewed all the coolant all over the place on the second day I had the car. Had to tow and have buddy do it at his garage.

It'* a cheap repair, only thing is it'll probably cost you more in time and skin swearing at how plastic can weld itself into an intake manifold then a mechanic would charge you. Most have a special tool to take those out. New part $5
