Questions: Mike, I went to pull out the old thermostat and replace it with the 160 deg version that I purchased - found out the previous owner had removed the thermostatic valve. I assume that was done so the engine would run cooler - is there any issues with not installing the thermostat in the coolant system

Alot of people dont have thermostats installed but I would recommend that you do.

Questions: Have a 1961 Willys wagon, looking for a thermostat with the jiggle pin. part # 812050-jp. can i run any other type besides the jiggle pin? Read that pin allows trapped air out, since the 6-226 has no bypass,there is the chance of overheating running other styles. Would like to stay original. Thanks, Ted

Questions: I have the 134 flathead engine in my 46 cj2a and just did a complete rebuild. The diagrams and other information I have received shows the thermostat installed with the spring of the thermostat up into the thermostat housing. That goes against every thermostat I have ever replaced. The spring part of the thermostat always goes toward the engine block or in my case into the head. Am I correct or is something different on these Willy's engines? Thank you for clearing this up. L Conrady
Question By: Larry Conrady on Aug 14 2016 1:22 AM
The spring does go down I do believe. See our diagrams on our website. Make sure you have the retainer in place as well to hold it in place.
