IMPORTANT THERMOSTAT NEWS - 180 degree for the HEMI
Over the years we have been changing to different brands due to failures of the 180 thermostats we use in our builds.
Years ago we used the Motorad unit. After we started to get failures with them not opening we changed to Gates. Then we started to have problems with them we went to Stant which also started to fail. These failures didn't happen on every unit but having repeated failures is not good.
Digging deeper, we found out that Motorad is manufacturing the majority of thermostats for most of the brands (except Mopar). As a matter of fact, Motorad is stamped right on the frame.
Two years ago we started using Mishimoto without fail until recently. We have had 2 fail in the last 4 months. Checking online I am seeing others are having the same issue as well.
We decided that we would order in some from Jet Performance thermostat which has been another option.
Guess what?
As you will see in the pictures they are made by Motorad. Didn't even test them, just sent them right back.
Time to do some research......
