Hi there . My name is ***** ***** Is it possible that you have a leak high up on the cooling system ? Likely the surge tank area ? Have you pressure tested the rap cap to make sure it is holding pressure ?

Customer: replied 1 year ago.
Coolant tank was leaking before changed it with the cap. That's when this started happening
Expert:  Andy replied 1 year ago.

It's gotta be some like that simply because you're not losing any more than just the one gallon . Have you pressure tested the system to 15 psi ?
