Okay so this is what happened. My car has been running pretty hot lately. its not only when i boost it but also when i just run the car under normal operating conditions for a while. so yesterday i decided to purge my coolant system. i followed the proper procedures but i noticed that nothing was coming out of the bleeder valve. i went to feel if it was just air coming out but i couldnt really feel anything coming out. i let if run for a while i sat in the car while i was doing this. then i just see coolant shoot up out of the overflow tank. turn the car off immediately. get up front the overflow tank is completely filled. im assuming that this is just a hell of a lot of air in the coolant system but was looking for second opinions.

 

Sounds like a bad radiator cap. Your system isn't holding pressure.

 

REMOVE the thermostat, bleed system with a radiator funnel and then be done with it...

thats actually what my tuner down here was saying.

 

It sounds to me like a bad thermostat, and since you're gonna replace it anyway, I'd replace it with one that has a "slightly" higher threshold.

 

the thermostat was actually just recently replaced.

 

I know ill get flammed but this is how I did when I changed to a koyo radiator. I filled the radiator with coolant/water and then open the air bubble valve to let the air bubbles out until there was no more visible bubble (might have to do this for about 10-15mins). Then I would leave it slightly open and drive around the block at different rpms and just let the coolant spill out from the open air bubble valve. Once u get back home pop the hood and close the air bubble valve completely and basically u should be air bubble free. U will have to fill up some water in your coolant tank but that is normal.

 

Also, be SURE you heater is on and set to the highest setting to make
sure coolant is flowing thru heater core.
