Thermostats - OEM, Gates, or Mishimoto

KTM300 · Nov 5, 2016

Getting ready to do radiator hoses and thermostats. Any recommendations on what brand to use: OEM, Gates, or Mishimoto? How about hoses: OEM or Gates?

I went with OEM hoses and Mishimoto thermostats.

What made you choose the Mishimoto thermostats over OEM? I haven't been able to find anything comparing the two.

Mishis run cooler. There's a thread somewhere.

I chose the lower temp thermostats for when towing.

I live in Montana, so I am not sure that I want lower temp thermostats, but I also am not sure that I want their higher than stock thermostats.

I live in cold county also. The Mishimoto's open 4-5 degrees cooler than OEM. Between those and the BPD 1/2 oil kit, I run a winter front cover to keep the temps up.

I run both oem and mishimoto. The lower temps mishimotos are great for the summer time, but not for winter. Stock stats for winter. In the summer i ran 197-199 coolant temp and 208-212 eot. After the mishimoto lower temp stats I see 179-186 coolant and never over 199 eot. These are running empty. Just before i took the low temp stats out a week ago, the truck would not get above 160*. I have 2 stat housing, and with the coolers ******d ,makes a 30 min job out of it.

Thanks a lot! Nice to get a true back to back comparison. I already ordered OEM stats and now know that I made the right choice. I wonder how the high temp Mishis would compare.
