At my first race last week, my car consumed 1 quart of coolant during the 10 minute pre-race practice; after the 25 minute race, it consumed 3 quarts which means it was nearly dry. I cannot see any evidence of leakage beyond a small spot of coolant in the trailer.
Coolant is distilled water and water wetter.
Max water temp was 215. The sensor is in the radiator.
I find it hard to believe that 215 water temp. would boil out that much coolant, so I am thinking a head gasket problem.
I'll do a leakdown test ASAP.
Do you guys have any suggestions?
Thanks in advance.
