I have posted this question before, but I'm now looking at this problem from a different angle.
When road course racing my 03 Cobra, after a few laps, it starts puking rad fluid out the rad cap. I put a new rad cap on, no difference.
Then after that, it happens all the time, and car overheats.
Into the Ford Dealer (car is under an extended warranty for another 3 yrs... sweet eh ?) and they say "Thermostat", and change it.
The next week, same thing, dealer changes Thermostat again, but can't figure out why it keeps going.
I talk with some other Cobra guys, who track their cars too, and they said almost unaimously to lower the coolant level in the tank by 2", so there is more "head space" for when it gets super hot. This does not work.
None of the Mustang shops I deal with have an answer, and certainly not the dealer.
I was starting to think I'd have to install a bigger rad or something, then a BMW guy says to me after I explain what's going on "you know you have a leaking head gasket don't you ?"... it was like a light went on !
Car runs 14psi boost.... overheat happens only after sustained boost racing (it's fine on the street).... so it may be blowing some compression through the head gasket, thus overpressuring the cooling system, and blowing it out the rad cap !
Is he crazy ?
Does this sound viable as to why I'm having this issue ?
