My buddy is having a coolant issue on his car. After a long WOT pull, the car will puke coolant from the overflow cap. Its been properly bled a few times and there shouldn't be any air or other issues causing it (unless his headgasket decided to go).
Its a 4.6 DOHC with the overflow mounted at least a foot lower than the vent cap for the coolant crossover. Low enough that when you remove the overflow cap, it just fills up the jug and leaks out on the ground. Add to that, the fact that its the size of a pop can.
In general, you want your overflow mounted above or at least at the same level as the rest of your coolant system, right? On most cars, the overflow cap is level with or higher than the radiator cap or other vent plugs on the motor... yes?
Can it even function properly as an overflow if its low enough to be filled by gravity from the motor?
It just seems strange and hes having lots of problems.
