Thermostat housing Gasket
Hi all,
I've been lurking here for some time, reading admiring, finding excellent repair help. I've searched and cannot find what I am looking for.
I've been struggling with cooling issues in my 92 sc400 lately. First, the reservoir cap seal went bad, so I replaced that. That was not the only issue. I noticed a small amount of coolant coming from the seal of the water inlet in front of the thermostat. So, I decided I may as well replace the thermostat while I was in there. There didn't appear to be any gasket other than the one around the thermostat itself. So, I buttoned it all back up with new thermostat. After awhile, it was still leaking from the edge. I decided to get some high temp RTV and re-install the inlet. After running for a bit, it ended up leaking too, so I ended up replacing the inlet housing. I thought that maybe the old one might have been warped. You never know with those plastic engine parts. The new inlet came with a felt gasket , so I installed this. It still appears to be leaking there just a little. I also have a tiny leak at the seal where the whole thermostat housing attached to the water pump. From the pictures I've seen, there appears to be a rectangular gasket at the base and an o-ring for that slides over a tube that goes into the intake manifold. I found a picture of the housing itself.

I am looking to see if anyone can help me out with the part numbers with the base gasket and o-ring. Also, how to get a good seal on the water inlet. Can anyone help me out with this? I’m so tired of this thing leaking. What am I doing wrong? Thanks in advance.

hi
I just joined and sorry to see that over 1000 people looked at your post and didn't bother to give any advice. But from what i have noticed so far . If the post had to do with adding 22inch tires or adding a 15,000 watt stereo system with tvs or adding nitro to you gas or changing out this and that to have the car roll on two wheels I'm sure you would of got thousands of responses .
