My car was overheating. I got it home and changed the thermostat and pressure cap. I decided to run plain water in the cooling system until I could see that all is well. The good news is that it is no longer overheating, but I have pink foam building up in the cooling system now, (still no coolant, only water). Could transmission fluid be making it's way into the coolant somehow? Doesn't make sense to me, but I know they both run through the radiator. What would cause the pink foam?
