hello i was just on fram's website looking up a model number for the oil filter for my 2005 dodge ram diesel and it lists 2 engine types a 5.9L Diesel Turbo (6) and a 5.9L Diesel Turbo HO (C) what is the difference between these engines i thought the 2004.5 and up had the HO engine. how can i tell which one i have?
thanks guys

 

If you stand on the drivers side looking into the engine compartment, and look at the side of the engine, there should be a plate or decal applied from Cummins that specifies which engine. I don't remember if it reads HP or Torque though. Do you have the window sticker from the dealer? Or, how about calling the dealer with the VIN and they should know. I'm thinking any service, or sales, department should know as it's still failry new.

I was looking into filters for mine and have read so many threads off different sites about filters, I decided to use Fleetguard. The service manager and mechanic of a Jeep dealer who is also a friend of mine strongly advised against Fram filters from experiance. Here is a link where I purchased my filters:http://www.scheiddiesel.com/filters.htm. And here is a link to Cummins for the filter numbers:http://www.cummins.com/na/pages/en/p...eram/parts.cfm. I bought a few oil, air and fuel filters so I would only pay shipping once for the next few service intervals. Hope this helps.

 

the 8th number in the vin will be a "c" if you have a high output

 

All 04.5+ trucks are the HO engine...
I second the comment on against FRAM filters. I have a buddy that put one on and hates it. I recommend FLEETGAURD as well. Any local big rig shop will carry them. or do what i did and ajpulley did and buy off the internet...

 

the sticker will show HP advertised 325 is what you should have, and then a big smile. (HO)

 

Oh ya, by the way, if you havn't changed your oil filter yourself yet, buy the93mm 15flute end wrench. It is well worth it. Bought mine through Snap-on, but can get it through others. Just so happens to fit the oil filter on my "87 XJ too!!

 

I'll third, forth, and fifth the "DON'T USE FRAM" comment. I have heard lots of horror stories about the filters failing and either stopping oil flow or letting all the junk through.

Use a real truck filter... Fleetguard or Donaldson

 

I'll echo the anti-Fram sentiment.

It doesn't matter which filter you use on your truck, because BOTH the SO and HO engines take the same filter.

Fleetgard # LF16035 for the fluted can, #LF3894 without the fluted end.

 

Both are the same power output.

I think the C is CARB compliant, where there are more OBDII monitors (and potential check engine lights).

 

hey guys thanks a lot for all of th info i really appreciate it and i will order the fleetguard filters i had no idea how bad the fram's were but thanks for the heads up.
PS
what type of oil do you guys use sorry i am a total newbie to diesel trucks but i def love mine : )
Thanks again

 

you'll find the rotella 15w-40 and delo 400 will be among the top used around

 

I was told by my parts guy that he needed to know if it is a 6 or a C for the air filter , is their a difference and are all 600 's C's . This thread looks like it has all the making of another oil war so I will vote for Rotella and hope that settles it .

 

Guys, I was told by my oil filter guy that the new filter is designed for higher oil pressure that the newer motors use. ks

 

fleetguard stratapore

 

Nope. same oil pump from 2003. Same oil pressures.
