I have an early 99 F250 that is losing coolant. I can full it up in my driveway, not move the truck, and lose , 1/4 to 1/2 inch. Driving a long way yesterday, 200 miles, I lost about 2 inches from the coolant tank.
There's no visible leak, no puddles, no white smoke from exhaust. I did see a few drops on the inlet pipe ONCE, but it still is losing coolant without finding coolant on the inlet.
I'm supposed to pick up our 7000 pound camper next Thursday and want to get this fixed before.
