Take it back to the dealer.

 

Yes it is annoying to have to take it back, but something doesn't add up. I doubt two new fans would go bad in that short a period of time.

Ask to see the old part when it is taken out, or if you can take it to a different FCA dealer.

 

This is beyond annoying. Unfortunately going to a different dealership is going to be very impractical. The nearest dealership outside of the one here in town is in Colorado. I'm already planning on seeing the service manager tomorrow morning.

 

I wonder if its possibly the electric condenser fan? The Hemi equipped Rams have 2 fans, one mechanical viscous clutch fan to cool the radiator, and an electrical A/C condenser fan inside the fan shroud.

Anytime the A/C compressor is commanded on the electric fan will be running.This includes defrost mode because the A/C compressor is commanded on to draw moister out of the air so you don't have moist air being blown at the windshield.

Try manually controlling the HVAC system to vent mode and see if the noise goes away?

Just a thought....

 

Use a marker to put a mark on the fan to verify if they do indeed change it.

 

I had this issue on my 2013. I drove it for over a year complaining to the dealership about the noise (before I new what it was) each service, however just didn't push enough to have it looked into seriously due to time, etc.

Eventually I had a complaint about the transmission.... and they replaced the viscous fan clutch. This solved the noise and improved the mileage. Anyways maybe this will help. I'm sure the part was the viscous fan clutch, solved the jet engine noise where the clutch doesn't release until high rpms.

 

Is switching to a dual electric fan setup not something you guys are wanting to do?

 

Never felt a need or desire to

 

Dropped my truck off yesterday and the dealer replaced the fan clutch for a second time. So far today the sound is gone and my truck doesn't sound "congested" as my wife puts it.

I've noticed the jet engine sound some too. Weird thing is the truck was totally cold..... when it needs less cooling anyway. One of our newer work trucks of 8 had a bad clutch fan that had to be replaced in a 2012 I think. Fan just barely moved, so opposite problem. Dealer originally said it couldn't possibly be a problem unless the truck overheats. It had the clutch fan and an electric.... so the electric had to work harder.

 

The kits i've seen replace the crank driven one with a thermostatic controlled fan that will turn on right around the same temp as when the stock fan clutch engages or have a controller so you can adjust when it comes on. You leave the factory electric can alone or use the same wiring to hook up the replacement 2nd fan if you buy a dual fan kit.

 

Thanks, I'll do some searching. Sounds like a better setup.
