I've had a coolant smell that I can't identify the location of when the engine is at 170F, about 30 seconds away from getting up to temp of 210F. I suppose it's possible that the temp gauge is lagging slightly and the smell is happening when the thermostat opens.
I can smell it inside the Jeep pretty strong at first and then it fades to the point of disappearing about 10 minutes later.
The radiator and overflow bottle are still full and I can't identify any drips. There's no drips overnight either. When I turn on the HVAC fan the smell goes away (bringing in fresh air).
I suspect a loose gasket someplace between different types of metal that weeps when the pressure surges from the thermotat opens and once both pieces of metal expand from the heat the gap closes back up.
Any ideas?
