Overheating while driving

What belt is that?and it would be make all those problems happen??

If the link on the new answer I posted doesn’t work type in this on google 1999 Jeep Grand Cherokee belt location and there are several things you can use as a guide to help you check the belt

And yes the belt keeps your alternator charged which keeps your battery charged, it runs your water pump which keeps the engine cool, as well as the power steering pump which keeps the steering wheel easy to turn etc

Thank you so much I will check tomorrow morning

Glad I could help you! You are welcome
