I have a quick question for you guys. My buddy bought a 02 Mustang GT with a Vortech on it. He forgot to check the coolant when he bought it. He brought the car over for me to detail it, I popped the hood and saw that the tank was empty. Me being the type of person I am, automatically thought the Head gaskets were bad. We take the car for a 15/20 min ride and it ran great the entire time (temp gauge stayed where it should have been), let it idle for another 10 min, and no issues. We ended up renting one of those head gasket test kits at Autozone https://www.autozone.com/loan-a-tool...ter/391378_0_0 when i opened the coolant reservoir, the tank filled with coolant, right up to the max fill line. The car ended up passing the test. We parked the car and he checked the coolant level the next morning and the tank was empty again. What gives? I am assuming there is air trapped some where?

Most likely was not bleed properly in the past and has an Air pocket.

My Buick (L67 car) does the exact same thing. I just leave it be. If it breaks, I'll know what the problem was lol
