Oil Change

I've got a 1998 Rexhall Anthem 33 ft. It has a 5.9L Turbocharged Cummins. It has what appears to be 3 oil filters, one orange and 2 white. Is that what they are or do they perform some other function?

3 oil filters?

Are you sure you are not confusing the fuel filters? My guess is the white ones are you fuel filters and the orange one is your oil filter.

My guess would be that the orange one is a fram oil filter and the 2 white ones are fuel filters as others have said. If that's the case, i would not reuse a fram oil filter on a diesel engine. I have read that the fram filters are not the best ones available and are not that much cheaper when compared to other quality filters. Just my .02 cents worth.

Hello there, great to have you aboard!! If you are going to replace those filters, don't forget to pre-fill them. You don't want to start the engine with dry filters. I use Shell Rotella 15/40 in mine. Fill the fuel filters with CLEAN diesel, pour the diesel to the side of the filter, not down the center.

Check your owners manuals if you have them, otherwise call Cummins and give them the serial number of the engine, from the side of the block, and or the VIN of the unit.

You can pick up filters from any large truck stop, I like Fleetguard, but Cummins will tell you what they prefer.

Here's a link to their web page
Hope this helps I'm sure others will chime in to help you also
Again, welcome aboard, enjoy
Happy Trails

Depending on your type transmission, on of the filters could be for the tranny. My transmission had a white spin on filter, a white engine oil filter and the thing on the rear that was orange was a Baldwin fuel filter/water separator. The final fuel filter was a cartridge type mounted near the top of the engine.

As stated previously, call Cummins with S/N, they can tell you for sure.

I agree with wizard, I have a large white filter which is an external transmission filter.
