33*, ECT at 220!?
Well firs of here is a little background on the truck
05 dually 127000 miles
Bullet proofed 4500 miles ago
studs, gaskets, egr delete, new oil cooler, coolant ect.
New injectors 1000 miles ago (one failed so i replaced them all factory)
Other mods in SIG
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.
