Thanks to Bismic for telling us about these Mishimoto T-stats. It is part # MMTS-F2D-03H
Mishimoto 200° on left, Ford 192° on right. I'm in the process of installing the Mishimoto....taking a break to show you guys pics. I'll have a video of the thermostat removal up later for those that would like to see.
The Mishimoto T-stat does NOT come with the 3C3Z-8255-AA o-ring for the thermostat housing. I re-used mine since it was fairly new. If you're replacing a T-stat that's been in there awhile, you might want to get a new o-ring.
The only thing I did was replace the thermostat. I just went for a test drive, and I like what I see so far. On interstate, cruising steady at 65 mph I saw 203 - 205 ECT with 95° outside air temp. I was not towing, and just me in the Excursion. With my fairly new Ford thermostat, my normal interstate ECT was 186 -188. I gained about 15° in coolant temp by only changing to the Mishimoto 200°.
Here's a Torque Pro screenshot while on interstate....
Well sure looks like the saved 18cents on the air bleed check valve hu? The main spring looks a bit beefier and I can't tell from the pic but is there a bottom spring in the misho?
Yea I noticed the bleed valve too. Yes, that main spring is BEEFY! Was fun pushing it down to install in the housing. I didn't pay much attention at the time, but I'm pretty sure there is no lower spring. (I'm not taking it back out to check!)
Like to know if you notice any increased mileage in a few days please.
Will do for sure, as I'm very curious myself. I have a 200+ mile trip next week.... I will fuel up before and after the trip. I normally average 17-18 on the highway....I'll update the thread with the results next weekend.
Thanks for sharing, under same load and conditions I see 198-201 with my new ford thermostat. But my oil temps are within 2 or 3 degrees under same conditions. You should see a little increase in fuel economy from your original low temps. Nice Job!
