I have a 1993 lexus es300 and my serpentine belt broke. After replacing it I noticed smoke coming from the car. The alternator is spinning but are the bottom pulleys suppose to spin freely?

if the bottom two pulleys aren't spinning by hand what do I do? and if they are not suppose to spin freely why is the belt smoking?

Yes, the other pulleys are supposed to spin relatively easy with exception of the crankshaft pulley. That's the large pulley on the bottom center of the engine. Now you know why the old belt broke. Whatever is not spinning is locked up. HTH. -Jim
