Smell?

[BBQBill]

I believe this is the place to ask this question. As you can see I am new here and so far you guys are the best resource for information on Powerstrokes.
I do have to admit (hope you don't hold it against me) I do not own a Powerstroke. But that being aside. My business partner does own one, and 05 6.0l F250 2X4. He has had such a time with this truck lately, First it was the transmission that failed, then the HP fuel pump, then the oil pump and injectors, now there is a smell coming from the right rear side of the engine compartment that just started after the oil pump repair. I have smelled it and it seems like very hot anti freeze and raw fuel, you can't smell it at the rear of the truck but when you turn the AC on, WOW!! it will drive you out of the cab. Any ideas? I will look at the truck again this weekend after a long pull to see if anything is visual, what should I be looking for?? Thanks I know that you all will help me with this problem.

I would be tempted to say an EGR cooler leak but that is useually acompanied with white smoke out of the exhaust. I guess if one of the clamps sin't tight ya mmay be getting the smell from there. The cooler is located at the right rear of the engine and the A/C intake is in the same general area. The fuel smell well look in the valley and see if it looks oily, has any puddles. You may have a fuel line leaking or the filter houseing.
Something of that sort.

Not trying to hijack, but had a similar issue today in my father in laws 04. When getting on it or when first starting you get the smell of antifreeze or something seeming to come from the ac vents. Is this a normal thing? It's raining here and really couldn't get under the hood but will as soon as possible to check for leaks. Any direction before I get under the hood would be appreciated.
