Bypassing the AC compressor on an 04 v8

EDIT: This is the 5.7 engine

So the compressor was having issues (I could hear the whooshing sounds when we started the car) and it seized up before I could get it replaced. At this point, with nearly 300k miles on the rig I don't want to replace the compressor.

Can I just bypass it with a shorter belt?

Thanks!

Possibly, but it will effect your defroster in the winter and be hotter than heck for the summer.

Sorry to hear of your AC woes. If this D is your daily driver, going without AC may get old in short order. Since I am not aware of an AC delete option from the factory, you would likely have to experiment with belt routing/lengths. Possibly, someone in the aftermarket has some type of idler pulley to allow you to retain the oem belt.
I suppose you could source a used compressor from a parts yard, and use that as your "idler." How about just replacing the clutch and its bearing?

I suppose I could try replacing the clutch, it would be about the same as a bypass. I jsut have not been able to find a bypass.

At this point putting another AC compressor is not an option - I jsut spent $1000 on shocks and the car, while reliable, has started to turn the corner and is costing more and more money every month. So I am going to have to either bypass with the AC comp or use a bypass pulley. The problem with a bypass pulley is that I simply can not find one for this model.

Hopefully you got more than shocks for $1K? Even the best (Bilsteins) run about $300 a set. Prob $500 installed. 300K is a pile O miles for any car. The Durango 04 Hemi's were known for valve spring and valve seat issues early on. If the noise issue is independent of the clutch, can you disconnect the clutch harness connector so it can't engage?

Did you get control arms and shocks? Like Don indicates $1k is a buncha sheckels just for shocks!

Just had a Tire shop tell me I needed Front Upper/Lower Control arms because of worn Ball Joints on my 2004 SLT. The Quote for that was $1,200! It's going to be someone else's problem soon as it'll be for sale. It'll be discounted accordingly and will be disclosed to the potential buyer.

For your current issue if it's the Compressor clutch that's seized then replace that and leave the wiring disconnected for it like Don indicated.

They actually sell a bypass pulley for it on LMC.com I would like to know what's up with these A/C Compressors going to crap!?!

He did say that D had 300k on it. As much as we would all like, nothing lasts forever. As an aside, if the compressor is seized, as long as the clutch bearing itself is not seized, the clutch pulley should still rotate, and perform as a "bypass", which is does anyway. If the clutch itself is bad, replacing it should cure the issue.

I know this thread is ancient... But I needed this information and still could not find it online in 2022... So the correct belt for my 5.9 liter HEMI 03 Dodge Durango is part # 900K7 at AutoZone. It is a 90 inch belt. No need to remove A/C Compressor or Pulley. Just simply install the belt as you normally would, except do not go around the A/C Compressor Pulley.
