To determine you CPL (Control Parts List) # locate your oil filler on the timing cover, not in the valve cover, and follow the arrows in the photos to locate the engine
On most coaches it is next to impossible to get your eyes above the the plate, so use a digital camera if you have one, or get a mirror and take a peek. More than likely, a good cleaning of the plate will be in order, before you can read it. Once you see the tag, look for the CPL box and note the number
. When reading the plate from rear of coach, the numbers/letters are upside down. To read it right side up, you would have to be lying on the engine
with your feet toward the front of the coach. This is where the camera is a big help.
This is a photo of my engine
plate, so you will know what to look for. I turned my camera around so the photo would be right side up. If you use the A/C adjusting bolt that is in each photo as a reference piont, it will help in locating the plate.
This plate also has the engine number on it. You can see the 8 digit number, beginning with 4669 on the right above "ISL 400"
