We have a 05 C9 cat, the oil pressure sending unit for the alladin is sending erratic pressure numbers.
They are always a multiple of what the dash gauge shows, usually double. If the dash shows 40lbs then the alladin shows 80lbs for awhile the changes to the dash pressure
I have a mechanic that will change it out when we figure out which one it is
The question is does anybody have the part number for the pressure unit that is sending to the alladin?
I would really like to have it here when my mechanic shows up in order to allow him to put it in without delay.
He is also going to show me how to do a correct service on the coach
Thanks in advance
