I have a 2002 Workhorse with the 8.1 L Vortek. In the engine mechanical section the 8.1 is not listed. Is this section available? I know the 8.1 is based on the 7.4 block. Are the rest of the engine sections comparable excluding CI items? ( Robert Balsinger, 05/25/2022 )

The 8.1L is covered in this manual.

Does this manual contain info on trouble shooting AC issues and repair? Can the PDF be it saved after purchase? Thx ( Fred Keeney, 10/29/2021 )
The AC system would be in the HVAC manual: https://www.ultrarvproducts.com/Workhorse-Manuals/2001-Chassis/1999-2003-Workhorse-HVAC-Service-Manual-Download ( Support )
My 2001 National Sea Breeze with the 2000 P32 Chassis has the 7.4L engine. Does this service manual cover this engine thoroughly? How many pages does this service manual have? ( Gary Nelson, 04/13/2018 )


    It is pretty comprehensive, it has a total of 5004 pages of which 431 of them cover the engine you have.

Given the variations in Workhorse P-Chassis manufacturing and engine matchups, are you able to tell me whether this manual (1999-2003 Workhorse Engines) will cover my 2003 P-Chassis motorhome? It uses the 6.5 Litre turbo diesel V8. I seem to have all sorts of problems getting the right parts for the combo. Oh, and I'm in Australia, which probably doesn't help.

Cheers, Lindsay
( Lindsay, 09/24/2016 )


Yes this manual does cover the 6.5L diesel powered P32. We have actually supplied a number of customers in Australia with parts that have the same setup as you :)
