replaced raidiator...still smell coolant..no leaks - 02/18/14 03:59 PM

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?

Coolant can stick around and stink for a while. If your Sentra has splash shields underneath, it can puddle up and take a while for the water component to evaporate and /or for the coolant to get splashed out of any crevices/nooks/crannies from driving. As long as the level stays normal and no visible coolant is leaking, you should be good to go.

Well that was my thought to..but Iíve had the car on several highway trips since the radiator was replaced 3 weeks ago. Would that not have burn it off by now?

Have you checked the coolant level? If it's low it may be a bad Intake Manifold Gasket.

Did you smell coolant prior to replacing the rad? And why did you replace the rad?

Take off the shields and go to a manual car wash and spray the engine compartment with soap and rinse thoroughly.

Let it dry and check for any new coolant leaks.

Sometimes the hose clamps need re-tightening or replacement.
