I am attempting to replace the oil pan on my 2007 Chevrolet Uplander. I have removed the starter, all 12 oil pan bolts, moved the oil cooler out of the way, removed 3 different brackets attached to the oil pan, and 2 bolts attaching a bracket on the underneath of the passenger side of the pan to a bracket. The oil pan does not budge and there is not enough clearance to try and get a putty knife at the seal. I have trid to pursuade it with a sledge but still not movement. Any recommendations on a bolt I might have missed or how to get this loose? Your help would greatly appreciated in helping me save a tow bill to the dealer and the high cost of having someone else fix ths. Thank you!
