Car smoking sometimes ???

What is your question?

I got my 2002 chevy blazer LS fixed last week because of a damaged water pump and everything seemed fine. I Noticed two day ago 9/4/19 when i drove to work in the morning, after i parked my car there was some smoke coming from the passenger side of the hood, it lasted for 2 mins then it stopped. My temp gauge didn't show any signs of my car overheating it was at the 210 degree mark. So i drove it back home and no smoke. Now today 9/6/19 it does the exact same thing. What could this be ?

How long has your 2002 Chevrolet Blazer had this problem?

2 days
