Bottom pulley wont turn

Asked by May 25, 2015 at 07:07 PM about the 2012 Ford Focus SE

Question type: Maintenance & Repair

I have 2012 ford focus, the surpentine belt
broke without warning, the belt wrapped
around the bottom pulley so tight we had to
cut it off. My question is what does the
bottom pulley go to and is it suppose to turn
freely? If it doesn't turn freely what is it im
suppose to replace?

Bottom pulley is the crankshaft pulley, no it will not turn freely, it turns with the engine running, follow the belt routing diagram closely with the new belt. Make sure you get all of the old belt out from behind the pulley or it could dislodge the new belt as your driving down the road.

That's why it wrapped around crank pulley, when it broke the engine still running grabbed it and wound it like a string. Make sure all pulleys are in line with each other, each rib on belt fits nice in grooves and has proper tension..... and nothing is frozen up, a 3 year old car the belt should have lasted longer.

With the belt off the rest of the pulleys should turn by hand. But not the bottom crankshaft pulley. The engine develops compression so unless all the spark plugs are removed, it won't turn by hand. If the air-conditioning compressor is locked up it might not be evident until you put the new belt on and switch on the A/C. If you hear an ear piercing squeal when you switch on the A/C, the compressor is locked up. HTH. -Jim
