I guess the subject speaks for itself. I own a 2001 Nissan Sentra 2.0. Had a new radiator put in it 3 weeks ago. No leaks, all clamps are working and no moisture around any of the hoses but when I shut the car off after a drive I still smell coolant on the outside of the car. When I open the hood, it confirms it because that is definitely what Iím smelling but nothings leaking and I donít know what to do. Any ideas? Would it take 3 weeks for residual to burn off?
