- '74 CJ5 258 3-speed, Dana 44 posi rear-end. Holley 390 cfm. Offy Aluminum intake, header, HEI, K&N
I have a '74 Cj 5 with a 258 and installed a mechanical temp gauge and the scale begins at 130 degrees. After driving it the reading is 135-140 degrees. I have a 195 thermostat in it. I checked the thermostat in a pan of water on the stove and it is opening and closing correctly. I used the original location where the factory gauge was. Why won't it register hotter?
