This new thermostat looks very similar to the NAPA 191. It has a relatively small inner diameter compared to stock. I do not have the fan mod so I had to use the 100% free fan mod, i.e. turning on the AC compressor, which only activates the lower fan on low! :naughty:Meister said:Well, 330toSRT8, with those numbers stamped in her, we know she's a fit and in the proper heat range.
Does the center orfice appear fairly large? The ones with the smaller center holes truly look small, disproportionately so.
If so you should be good to go.
I'll try to get by NAPA later today and see if I can track one down, as well as the 191, and get some pictures.
Thanks much for the info. Pls. let us know where EVIC shows her to be opening.
Ambient temp: 64 degrees.
After installing the new tstat I let the car warm up to 217 then turned on the AC. After approx. ten minutes the temp was down to 190. Cruising on the freeway at 70MPH it was 185-186 with AC on and 185 with AC off. At low speeds it was 186-190, but it would rise rapidly if I floored it. BTW, cost was $8.
One more thing. The 13mm socket was loose on my bolts. A 1/2" worked much better to avoid stripping the bolts.
