So I have been doing some research I have a 99 GMC with the 7.4L and the temp has been roughly 185 and when towing through the mountains and ac on it jumps to 210 is as high as I saw it go before I turned the ac off. Through my research I hear most trucks have shrouds mine does not have a shroud...
I am gonna go the procharger route myself but I only pull a 26 foot aluminum camper with a rzr inside. But I am interested in the 411 swap could you share your diagrams?
To the gentleman who made this thread you sir a god dam rock star I was kind of figuring this was the issue with my truck once I turned on the ac and could smell something burning would of taken me a lot longer to find/ remove/ replace hats off to you
I did a little searching but couldn’t find anything. I have a 99 GMC crew cab 7.4l drw and it runs consistent roughly around 160 or the middle mark on gauge (I know they give crap readings) but now that it has warmed up and I turn the a/c on the temp runs up to 210-220 when at idle as high as it...
