Ok, so as some of you know I have been smelling a burning antifreeze smell lately when my truck is towing or under load... So the other day I brought it in to the dealer (after taking out my SCT for a few days) and they looked under my hood. My truck was over a gallon low on coolant, so he got me an apt. said that it was probably my head gaskets leaking (under warranty still). So I drop off the truck yesterday, and they call me a few hours later and say that it was just a "faulty radiator cap" that was causing the leak and hot smell... Does this sound like a big load of BS? Or is it really possible that it could be that simple?? Also while the truck was in the shop, I asked them to replace my factory 1 3/4" blocks in the rear with some factory 4" blocks. With my 8" fabtech lift and no air in the bags the rear sat about 2" lower than the front. $385, not bad I didn't think.. Anyways let me know what you all think of this???
