Purchased a used '13 Jeep GC @ a dealer in Denver last autumn and last friday I brought it to our local dealer to remove the snowtires, check the factory recalls and to have an oil-filter change (first one while in our possession of the vehicle). They were unable to remove oil pan drain plug and said the bolt head became "rounded" with repeated attempts and that the oil pan would need to be replaced at a subsequent visit & at a cost of $1400 (initially I was told over the phone 1400 and later was told between 1100-1400). I was told the ONLY alternative was to remove the oil pan but that I could contact the dealership conglomerate that last changed the oil in Boulder and/or that my auto insurance company might reimburse us for the necessary repair. I asked if the oil pan drain plug could be removed by some method or drilled out....No. When I picked up the vehicle, I reviewed the printed invoice (#1 - 01F: CHANGE OIL AND FILTER ON A GAS ENGINE Work performed by _____ COULDN'T PERFORM LOF. DRAIN PLUG WOLD NOT COME OUT. RECOMMENDED OIL PAN REPLACEMENT. CUSTOMER DECLINED and scheduled the earliest available return appt for the oil pan in two weeks. At home, I crawled under the vehicle to view the rounded drain plug bolt head and found the bolts on the skid plate didn't appear to have been touched (to remove the skid plate for better tool access like with a pipe wrench) and GOOGLE searched (rounded oil pan drain plug head). Monday, drove to Doc's Auto Clinic to discuss the use of pipe wrench after removal of the skid plate vs. an alternative method like an Irwin bolt grip socket and to schedule the next available appt. Doc reassured me that he couldn't recall having to replace an oil pan because of stuck-rounded oil pan drain plug. Yesterday (thursday) @ Doc's, the "rounded" drain plug did require two bolt grip sockets (first one cracked) for removal but didn't require removal of the skid plate. In their opinion a flush of the crankcase was not required, based on inspection of the drained oil (coincided with previous documentation of the oil changes/mileage on the Carfax when we purchased the car). They placed/gently torqued in a new magnetic drain plug (I had prepurchased @ auto parts store), replaced the filter and filled the crankcase with synthetic blend (my request) all for $60. Happily (relieved), my credit card payment and thank yous were accompanied by a couple of cold, six packs of assorted microbrews from Arctic Liquors and my assurance that both of our vehicles would now be serviced by Doc and his adept team. The four indiividuals that I had any contact with (@ Doc's) could not have been more professional, amiable, competent and confidence inspiring. Disclaimer-My only previous contact with any of the individuals at Doc's was with Doc during a group mtb trip to the Hillyard-Fowler-10th Mtn Div hut last summer. (On the drive home I did stop by the dealership to cancel the oil pan replacement appt, speak with the service manager about the experience-outcome and that we would no longer be bringing our vehicles to their service dept-previously 10 yr relationship with 4 vehicles).
