QSC aftercoolers - Where to find?

[Zach312]

Does anyone have a location on where to find Cummins QSC aftercoolers. Seems they are sold out any place I call. Figured I'd toss the question out to this forum. Looking for part # 5443623

I can’t help but I can confirm that Cummins has a major shortage of these frequently replaced items. My buddy has QSM’s and same backorder. Saying 6 months or longer at this point, but it keeps getting pushed. This is for after coolers, heat exchangers and exhaust manifolds, etc. He called all over looking for anything used to buy time while waiting on the back order - no luck.

Hopefully you can repair or rebuild yours to get you by in the meantime!

I've done a bit of calling around as well for some Cummins parts, seems like pretty much everything is on back order with no real firm date of when things will be available.

I had my local Cummins dealer pull my aftercoolers and Fuel/gear coolers last week to find the Fuel/gear coolers were original and had to be replaced and recommended that I replace the aftercoolers too.

He said that he had the f/g coolers, the a/coolers were back ordered and no one had them, so I told him to service mine as best possible and reinstall them. After making a couple of dozen calls a day or so later, I was able to find a dealer in Alaska that had one, bought it and it arrive 24-hours later! The next day, my dealer received a delivery of two!

My question is..... when did they change to the newly designed a/coolers I'm installing, has anyone changed their a/coolers with them and do they need/can you install the auto condensation drain on them that was mentioned in another thread on this site?

Oh man… what a nightmare. Are they all coming from China?

Give these guys a call, if he can't find them they're not around anywhere.
