To make a long story short my wife crashed the truck several months ago. Someoone hit her at 40MPH right on the front bumper and I basically had someone replace everything in front of the engine itself. I finally picked it up from the autobody shop and it still needed to visit a true mechanic to get everything dialed in before daily use. I picked the LC up late Saturday and there was a check engine light on.The truck would run ok until about 2500 RPMS and then I would run rought. On Sunday I drove slowly about 2 miles to get a code scan thinking it is a ignition coil after searchign on Mud. As they are getting the machine ready I notice it idling a bit ruff. I open the hood and get on the gas a little to see what I can find and I hear what sounds like the fan hitting something and then a POP.The Fan breaks off. It is not the fan that is broken. ( Well the blades probably are now) It is the rod that exits the engine that the fan connects to.Please tell me I will not have to remove the top of the engine to replace that rod the pulley and fan connect too?Once my silverstar membership kicks in I will post pics but the rod snapped flush with where it exits the engine.How big of a job is it and what can I expect the mechanice to say.
