Jeep 4.0 Cherokee more consistent temps!!!
This worked perfectly in my Jeep 4.0 Cherokee. Jeeps notoriously overheat, run high temps. I got rid of my mechanical fan and went with electric fans for my radiator but my thermostat didn't get along with my fan temp switch as my fan temp switch kicks on at 195 but then shits back off at 175. The thermostat was 195. This caused my thermostat to open and close constantly. I used the smallest one and it has given me consistent 190 all-day. I realize that it's not a listed vehicle but I'm so glad I took the chance.

Consistent cooling
On a Dart block, 500hp, 406cu in. small block Chevy, I started out with the medium sized restrictor but had better cooling with the smallest one. This restrictor made it easier to get air pockets out of the Dart block and provided more consistent temperatures while driving than the 160 and 180 degree thermostats I started with.
