I've just picked up a 95 ranger 4 cylinder. It has a good many miles on it so I thought I'd do some routine maintenance. After t-stat install, I can NOT get it to warm up to anything warmer than 175(temp gun). I flushed out radiator, heater core and all hoses. I can't even burp the system or add anymore 50/50 other than what I put in the radiator because the t-stat won't open. Dummy gauge reads low but I always check it in various places with a temp gun to be sure. I've seen others with this problem and wonder what is going on? I had a 180 t-stat and thought that was the problem so I took it back apart and installed a 192 degree one. I saw where the housing could be the issue and that water could get past the t-stat even when it is closed. I installed an extra o-ring to push the t-stat hard against the housing. With the extra o-ring, I can't blow air past the t-stat now so I KNOW it is sealed. You would think riding around in 95 degree weather with the A/C on would warm it up. When I stop and raise the hood, the temps drop down to the 160's. I know cardboard in front of the radiator may help but what is the real problem? I know this truck didn't do this when new?
