Team, we have a 2005 2.7 that has been making some, what I assume to be pulley, noise at idle for a few months. I looked but was unable to determine by visual inspection if one of the pulleys was having an issue. A couple of days ago the drive belt started smoking. She immediately pulled off, turned off the engine and we had it towed home. The engine will not turn over now. It begins to turn and stops when the belt tightens. I assume we have a frozen pulley preventing the engine from turning under starter power. it may be important to note the A/C did not cool late this season so the compressor could be the culprit. What do you all think is the likely cause given the age of he vehicle, etc.? Am I possibly looking at a water pump/timing belt replacement? If I remove the drive belt and the engine turns then an exterior pulley? Thanks in advance for any advice and guidance with how to proceed.
