On the 2009 K1500, they believe they are going to sell the truck and don't want to go any deeper. I finished what they approved and gave the truck back to them this morning. It was the first time I had used the stretch belt install tool and it worked flawlessly. I have a great MAC tool 1/2" ratchet, long handle, and a 24mm socket and the belt went right on and there is no more noise at the a/c belt. When I did the oil change, I did identify 2 leaks. One from a loose old oil filter and the other from the oil cooler line block off flange. I explained to them what the repair would take and they will think about it. It is seepage leak and not a steady drip leak. Rest of the engine is dry.
