Belt numbers for a 2004 Holiday Rambler with Cummins 330 ISC

[Mtn.Mike]

I have searched the forums and got some numbers for what might be the serpentine and alternator belts but I want some info from those who own the above rig or one similar with the same engine.


Thanks, Mike

This will do it for one of your two belts:

Serpentine Belt = Dayco 3911581 = NAPA 25080690

Thank you Robi. 1014. Now all I need is the A/C belt number.

My manual lists Dayco 15465 for the AC v-belt. But I have not replaced mine, so I can say "fer sur" (or offer you a NAPA number) like I did with the serpentine belt.

Mike not sure if this is the same as on your coach, but on my 01 Diplomat the air conditioning compressor belt is a 15465 Dayco. That is a 'Top Cog' belt. I crossed it at NAPA but their belt was not the same even though it crossed. A Top Cog looks like the belt is on upside down but it is the way it is supposed to run and be installed.
