Two belts vs one

My engine blew up and it had two belts that ran it and the replacement engine has one does that matter? Mine YJ is a 90 and the replacement is out of a 91 would that also matter?

the one belt sould be fine, most of the time the 2nd belt is an accessory belt that just powers one or 2 pulleys since it wasnt designed to travel the whole belt length. mine is a 95 with the original motor and it just has one drive belt.

As long as they were both V belts you should be OK if it one has a flat belt it probably has a reverse rotation water pump then it wont.

4cyl or 6?

90 was the last carb on the 4.2 6cyl, 91 went to fuel injection on a 4.0
