Thermostat MotoRad or AISIN

I still changed my thermostat to an Aisin unit for peace of mind, so far so good.

I just bought two thermostat related parts off rockauto that are both Aisin yesterday.

I have installed them in two rebuilt, and they are working perfectly fine

It's a very easy thermostat to replace, I just did it a couple days ago on a 2008 Hyundai Sante Fe with the big 3.3l V6. The gasket comes with the OE Aisin thermostat, too, making it even easier.

I use them all the time with no issues.

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 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.
