My thermostat housing was leaking and I finally got it to seal up 11-28-07. Details in this thread. Since I installed the new housing I have been leak free as far as coolant goes. This morning steam started flowing from under the hood. Temp was on the R in normal so I just cruised on home and backed into the shop. Quick look underneath and sure enough she was bleeding again, a regular river of coolant After a few minutes of diagnosis I found that once again it was the thermostat housing seal.
The housing and seal were new on 11-28-07 so we are talking only about 1.5 months and probably less than 300 miles. I took it apart and everything looks fine. Rubber ring is intact and surfaces are clean with no irregularities.
Has anyone ever used silicone on the housing seal? I just ran a small bead around the groove that the seal goes in and then another small bead over the top of the seal. Once it sets up we will refill it and see what it does. Any better ideas? I guess next step would be a new water pump so that the lower surface would be new? Water pump is only a couple of years old. Could I be getting excessive pressure that is blowing coolant around the seal? This time it was a river not a drip.
