Thermostat MotoRad or Duralast

installed new Duralast (motorad) 207F thermostat and it seems to have fixed the issues. Gauge is coming up to just a hair under the 210 midpoint and the live data on my scan tool shows the ECT is running between 205 and about 214F after fully warmed up and moderate level accelerations and driving. The front heat is now scorching hot and the rear heat is much improved as well.

I got a duralast part from autozone with a lifetime warranty for 25 bucks. My jeep has been been running well for the last year since the change to the duralast part

I use them all the time with no issues.

I used one of the MotoRad safety thermostat's that have a 1/16" hole already in them, in my 84. So.. No, I don't think you'll have any problems adding a hole.

Installed a Motorad thermostat and noticed the temp gauge dropping on the highway. I never had this issue before I changed the tstat

Had a Motorad Fail Safe a few years ago and it was a POS.

Tried a Gates from RockAuto and it was a Motorad in the box. Installed it anyway, it seemed to hold the temp *lower* than the 170 Stant did, and my engine cooled all the way down to cold when I went down a long grade.

I'd advise taking that Duralast thermostat out and installing either an OEM unit or a unit from a trusted brand (such as Stant). If the Duralast gets stuck in a closed position, the SUV will overheat. If it gets stuck in an open position, the engine won't reach operating temp, and you'll have issues such as running rich. Duralast has a nickname we techs refer to: Duracrap or Dura-doesn't-last.

I tried a parts store Motorad, failed. Tried a Napa gold stat that turned out to be repackaged Motorad, failed.

Every 6-7 months the cheap garbage scam of a brand Motorrad remains to be the only available thermostat I can access. I do the temp gun test, I verify my sensors are correct. I burp the cooling system. Everything. I’ve gotten so good at the job now. Every brand of thermostat I’ve tried in Canada is a Reboxed Motorrad. Premium to Economy. 7$-25 they’re all the stupid same. Parts source, Gates , Napa , Autovalue , “mopar” from my dealer. All Motorrad at different prices. I know of 2 they make, the standard oe 195 which is usually economy line. And the fail safe one they make. Both have catastrophic failures, either get stuck open, spring blows apart. Usually after 6-7 months they stop working entirely or the thing slowly stops letting the Jeep get to temp and I dread reliving the Motorrad Groundhog Day effect. It’s a garbage thermostat. People have argued with me that they make OEM equivalent parts and they never have issues but I’ve had nothing but issues.
