Thanks for the replies! The sensor was not out of the block, it snapped at the connector so no coolant lose. Unfortunately I had to drive the car for that 1 day. Turns out the senor didn't cause a problem but the idler pulley did. I guess the tension of the new belt was too much for the old pulley which broke and shredded the belt.

Got it towed, picked up a new pulley & sensor at the dealer next day and we're good now. Only problem was getting the spring clip for the senor back in properly. It's in but not as it was when I removed it. Very tight space to work with. I'm hoping someone can give me some insight on how to get that clip in correctly.

Thanks again.
