OK so I got my upgraded housing kit from Tousley the other week, put it on and everything went very well. Last week I was cleaning the throttle body and noticed coolant on top of the housing where the temperature sensor screws in. When I went to remove the sensor (which I put teflon tape on when installed), it snapped off (pictures attached). I assumed it was a faulty sensor (bad quality, whatever), so I bought a new one obviously. Got everything put back together this last weekend (did the valve cover gasket as well), and after a week of driving, I checked the coolant temperature sensor while checking the oil, and sure enough there is coolant on top of the housing again. Any ideas?

I bought the same parts from Steve & have had 0 issues with mine...probably a bad part...I used a liquid thred locker instead of tape. My original one started dripping at around 100,000. Must have had one of the better one's.

I've been in contact with him and he suggested not using teflon tape this time. We will see how it turns out.

I did the same upgrade on my'03 and I had the same leaking issue when I first installed it, and it was because of the Teflon tape. I reinstalled it with a liquid thread sealant and it worked much better, no problems after that. One of the best peace of mind upgrades I ever did.

Thanks for the write-up !! I did mine last week and it was pretty easy, I just had to fight with the hose clamps and pliers to pop them out. Also I used liquid thread sealant rather than teflon so no more leaking problem. The contour t-stat seems beefier than the oem, even the type of plastic used looks strounger.

You might want to take a look at your valve cover gasket. I've read that hot oil drippin from the top of the head onto the housing could shorten it's life. Mine was leaking so I changed it at the same time, i wouldnt have wanted to ruin the brand new t-stat.

Finished mine last night. I used the Teflon tape. I will have to keep an eye on it for any leaks.
