coolant color

every time I start my truck the exhaust smells sweet. today after towing 50 miles I check the coolant and it is low. but both bottles look like green coolant.

Bart,

That is a mystery for sure! I have nothing to add. But please let us know what the dealer says if you decide to have them look at it.

I would agree.

Motorcraft Yellow 50/50 straight from the bottle.


This is what my primary system looks like after the dealer "flushed the system" and replaced the old orange coolant with the new yellow.


And just for reference - Motorcraft Orange 50/50 straight from the bottle.

Let us know what you find. I swear I have the same but dealer could find nothing and coolant level was fine.
