Past few days coolant is coming from the overfill hose that connects to the coolant reservoir.
No leaks anywhere on the coolant reservoir. even replaced the caps. holds pressure.
ONLY drips from the overflow went PIPE.. when driving or parked when truck is on
Added half a gallon while cold and after 300 miles reservoir was half. Truck runs great no issues no overheating nothing. Doesnt make sense any help would be great.
