If I fill up my coolant overflow reservoir to the mark it will slowly use up the coolant up until the reservoir is empty. Sometimes within just a few hundred miles.
That said the coolant in the radiator will never get below 3/4" of an inch below the radiator cap no matter how many miles I drive the truck. Once it's to about 3/4 or 1" it stays there for good.
Radiator cap looks good. No visible leaks whatsoever. No coolant on the dipstick and no noticeable white smoke from the exhaust. Sometimes I'll catch a whiff of coolant when I shut the truck off and pop the hood but I've looked it over a hundred times and haven't seen so much as a drop.
Makes no sense to me any ideas?
