160 T-Stat operating range question
Just wondering what temsp ou are seeing crusin g with your 160 t-stats? I went from a 180 to 160. Car idles @ 175 with no fans and cruises at about same in 87 degree temps. I set my fans to come on @ 180.
My 180 ran @ 196-204 all day.

I messed around with half a dozen thermostats before I got one that I was happy with. The "rating" is BS. I had to test each one on the stove. I had one "180" that opened at 195, a "187" that opened at 195, two stock 195s that opened at 194 and 196, and two 160s that opened at 160. Maybe your "180" was opening at 195. You really need to test each one, unless you got lucky and found one that suits your needs, regardless of the rating.

I also tried several, some were junk. I bought one from a sponsor here, it opened correctly, but wouldn't close when it should, ended up still flowing at 120. I sent it back they said it was operating correctly.
I bought a Hypertech 160 and it works perfectly.
It starts to open at 160 and is full open at about 175. My ECT stays at 175 (cold, winter) to 190 (hot, summer, stop and go.) with fans reset.

Why swap out Tstats? It'll only affect at what temperature the the coolant starts flowing thru the radiator. My experience with lower temp tstats has been that it runs at the same temp but has trouble warming up in the winter. If overheating is an issue, or even running too hot, wouldn't lowering fan turn on temps be a better solution than a lower Tstat?
