Coolant system
 

So the other day my main drive belt broke (serpentine belt). Well a couple days after I fixed it my MC starts to over heat. I'm not sure what it could be, still fairly new at this

How many miles and which engine? How old was the belt? Did it break due to old age or is there a malfunction in one of the pulleys that caused it to break?

Could you have possibly routed it incorrectly and its spinning a pulley the wrong way?

Is it possible it overheated when the belt broke? Just wondering if perhaps a gasket is now leaking or something warped from that.
