Fan operated properly, kicked in at 180, in fact one hot day I ran the fan the whole trip to keep it at 240 degrees and then I pulled the thermostat. Did the trick. Runs as cool as the coolant temp now. Retarded idea...

Is there any negative side effects or issues running without t stat??? Jus wondering it wasnt always an issue so something else must be wrong and in case that prob is solved having it out could cause more probs.

YES, BIG PROBLEMS! -- FIRST AND FOREMOST! that is really bad mis-leading information. The oil thermostat, when removed, the oil will BYPASS COMPLETELY the oil cooler. the oil will no longer flow through the cooler but instead permanently bypass it.

It is explained at 1:41 in this video...





NEXT: YOU ACTUALLY WANT the oil to be above 215 degrees to keep moisture burned off at all times. this prevents moisture buildup and rust from forming on the components like at the in the top of the head around the rockers, especially when the engine sits. That is the whole point of the oil running above 200 degrees.

That persons statements are a flat out lie!. I have seen many people who tried just that only to find their oil started overheating with the thermostat missing. -- therefore, the last 2 posts from 'sirrepairsalot' are clearly a flat out LIE!. If he had actually taken the thermostat out of several trucks then he would have had several trucks with oil temp problems right away!> I am not going to tolerate such statements that spread mis-information onto others like this. In this case it is a little too obvious!.

The guys profile says he has been a mechanic for 17+ years. I feel bad for his customers if after that many years, he still does not understand how an engine and its many systems actually work.
