I did the install last week. Car warms right up now. On the highway, the needle stays at 12 o'clock. I noticed yesterday that I had a coolant leak coming from the t-stat. Looks like the gasket didn't seal right. It is coming from between the t-stat housing and the black plastic piece (flange??) thats connected to the hose.
When I installed it, I put the gasket around the flange and the t-stat on top. I then pushed it into place and bolted everything up.
Before I take everything apart again, I just want to make sure I have the correct order of installation of all the parts.
I searched the forums already, but couldn't find the answer I was looking for. This is for a 99.5 1.8T AEB engine.

*edit* <i>now that i reread your post, i think we are saying the same thing</i>

i think i remember the oring going into the groove in the t-stat, which would put it inbetween the water pump and the tstat, with the black pipe bolting over everything.

So basically, the o-ring goes around the t-stat?

If you look up the timing belt install under the Tech section, it explains which way to put it in
