'13-'14 Ram upper radiator hose

[LIKE2BUILD]

Hey guys, this is an FYI if you have a ''13 or '14 Tam with Cummins. It has a dual radiator system and the upper return hose has a Y in it to feed both radiators. THIS WILL CRACK. Mine did on my trip out west and luckily I was near a dealer that had 4 in stock. The parts guy said they replace a lot of them. It's about a 30 minute fix.

There's a place Black Market Performance that makes a Billet aluminum replacement Y pipe I wasn't able to get that while on my trip but I will soon. Basically there are 2 types of OEM Y pipes: those that have cracked and those that will crack.

I am glad RAM went back to the single radiator. I have no issues with cooling with combined at 35K towing in the West.

What was the reasoning in the first place for the two radiators, and then going back to one, it sounds like other then this Y hose problem, the two radiator system works okay. Never had any cooling issues.

Is this done without having to drain the coolant, being the upper hose ??

That Billet aluminum looks like the cure. I too will look into that, although I have had no problem so far.
