Hi everyone.
I was sitting on the freeway on he way to work, and the CEL popped on and my idle went to s***. Low stumble. When I arrived, I popped the hood and found out that the fan shroud had somehow come in contact with the fan blade, and caused the fan to not spin. I am not sure how long it was in this state, but at least on the way to work(15 miles).
I wanted to ask everyone -- if they know what could be damaged if that blade was not spinning/stuck against something. Since I removed/fixed the shroud, the fan spins, and everything seems to be working as normal as far as the fan clutch goes. However, the low idle has not gone away. I am also BILLOWING smoke out of the exhaust. This truck always did that, but now its like a smokescreen that blinds the driver behind me as I gas it from a stop. It is a very heavy white smoke.
I am very worried, that on my way to work, I may have overheated the engine. My thermostat never went over 1/2 way up, but I have no idea if it is actually working. The engine certainly got to a "hotter than normal" state after I got home from work. On the freeway, it was fine other than at a stop, where the idle was REALLY bad and the tailpipe was blowing a bunch of smoke.
The only codes Im getting, are 12, 25, 26. I checked the knock sensor plugs, and they look fine.
Thank you all,
Chris
