Coolant smell

17 2.7 4cyl. 20k miles. I sometimes notice a coolant smell when I walk past front of my truck. I opened the hood and I smell it on the driver side top part of radiator but there is no signs of leaks anywhere. It’s dry as a bone. My coolant level is between full and empty and haven’t noticed it get any lower. Any ideas is this normal on these trucks?

 

Mark reservoir and confirm you are, or hopefully not, losing coolant.

 

Probably vapor smell. Take off the cap and look at the gasket. If it looks questionable, get a new cap. Less than $20.

Coolant bottle has a overflow hole and hot coolant smell comes out of there.

 

Why do I smell it on opposite side of the bottle though? Can you just sniff the top driver part of your radiator for me after a drive and see if you smell a faint smell of coolant?
