    check the radiator fluid level, at the radiator, overflow, and intercooler resevior. and also check all the lines, it's probably a very slow leak so if one of the lines is bad it'll be hard to see. if there is rubber hosing under some of the lines, check it to make sure it still looks ok and not somewhat shiny or corroded in any way, if it does, it'll be the hose above it most likely. also check the gaskets on the caps make sure they're not shredded.

    I had the same problem where my '04 wrx would overheat randomly, turned out it had a small leak over in the fluid hose over the turbo intake.

    Can you describe the behavior? Does it overheat if you just leave it idling, or do you have to be driving? City or highway driving? How many miles on the car, and has it ever had a coolant flush? How old is the water pump? Does it matter how cold or hot the weather is?

    See your other thread. Burp the system.
