2006 Chrysler 300C Hemi heating up
 

hey guys I had a shop changed a cracked or damaged radiator yesterday.

Today i I drove the car up a mountain ahd the car is heating up.

Looking at at the water reservoir the water level went way above the max but also came down when the car cooled down. When the level was back at max the water seemed to bubble. Not sure if that’s due to boiling or another problem.

what should I look for? Any tests or troubleshooting ideas?

Thanks,
Nir

How many miles or rough time estimate of running when this happened after picking up the car from the shop? Could have air entrapment in the cooling system from the radiator change. Did the radiator fan(s) kick on at any point?
