On so lately here in missouri it has gotted down in the low 20s a coupel nights mostly high 20s, low 30s. So ive had a piece of cardboard in fron of the radiator to help get the truck war since i have a short drive to work and around town. This morning it was 40* and had to make a 30mile trip. I left the cardboard in for about 10 miles or until the truck got to 180* By this time it was 33* out. Took it out and the temp stayed around 185 for a couple miles then it started to rise. It got to 226 FAST and i pulled over and popped the hood. had coolant coming out of the degas lid. I let it cool to 185and took off all was fine. let the truck sit for an hour and all was fine still until i got about half way home and it started to climb again to 216. I pulled over and let it idle and it dropped below 200. I noticed the heat would blow cold everytime the ECT would rise. It did this again on the way home. But I heard the fan kick in and ECTs dropped to 176 befor the fan let off.
I cant wrap my head around this. would the valve before the heater core cause an over heat problem? I dont drive the truck hard and have not had a problem like this before. I wouldt think the new head gaskets would have blown. Coolant level looks fine.
