Mine’s not a smell like hot coolant – just a hot smell as if it was starting to overheat a bit. I already replaced the expansion tank which had a slow leak so I know that smell. Let us know what you find.

Mine just smells hot since i changed the thermostat back to the original temp. Am waiting to see if it goes away after awhile. If you find a sneaky drip, let us know where it is so we can look too.
