6.4 temp guages pegs out

youngstroke · #1 (**permalink**) 11-01-2012, 04:28 PM

We have a 2008 6.4 that the gauge goes from normal then falls over to hot. Then it goes into power loss. You can't drive it over 50 or it does this. However, it's not hot at all and no smoke. And it wont get hot if it's cleaning the exhaust filter. Is there any way to just unhook the gauge or anything so that I can drive it for now.

I'd be checking your engine oil temperature...i'll bet its getting hot...the engine temp gauge will act just like that and go into reduced engine power to protect the engine...chances are that you might have a bad engine oil cooler...
