Funny you should mention this. I was thinking the same. At idle I did hit the magic mark to get the fans to fire up.

But without the fan I would expect some change. The change was so little I was thinking the t-stat may have been stuck open all along. And my economy has never been as good as I think it can be.

I think I will replace it just to be safe. Can I assume the location is front on top. There appears to be a t-stat housing between the dist and cruise actuator. It also appears to have some silver colored caulk around the base. Do I need some gasket in a tube or are there regular gaskets used for this? Just want to make sure I have all the right stuff before starting.

Thanks.
