2003 Chevrolet Venture Question: Oil pump



Hoppyd01, Espanola, NM, December 12, 2010, 15:08

Need info on how to pull the oil pan down and replace the oil pump. Where is the oil pump located? Is it in the pan as I have heard it may be external.

    Don't even try to do this yourself. You haven't even told me which engine you have. Both engines are different and unconventional and require a GM expert mechanic to do this kind of work. I looked up the procedure on both engines and I don't recommend it to anyone who's not familiar with the designs. Find a GM specialist to give you an estimate, and if you're on the phone, find out which engine you have first before calling.
    Here's a directory link for you:
