Default coolant issues. need help!

so i took off my whole stage 4 set up and went completely back to stock. (02 wrx) i turned on the car and no leaks. took it for a ride and it seemed normal. everything sounded/looked and felt normal.

2 hours later i turned the car on to drive to work and at a light the gas light caught my eye. so when i saw that i also noticed my temp gauge was WAY past H.

i pulled over immediately and remembered that i forgot to "burp" the coolant system after the turbo swaps. so i did just that. it bubbled and overflowed. i turned the car off and let it cool off a bit and repeated. i did this for an hour and still nothing changed. the temp would start normal then rise up to H. i re checked the turbo coolant lines everything seemed fine. i even re adjusted the clamps on the hoses. i felt my fingers around them, no leaks. a few hours later and many attempts i attempted to drive back home. the temp seemed to be fighting itself going up to H then falling down to normal temps. while all this is happening btw my HEATER isn't working at all!! it shoots out cold air UNLESS the temp is at H then the heat works.

any suggestions on what i should do or what the problem should be?

thanks

(sorry so long)

if your heater is still cold you still have a lot of air trapped. Keep burping

You are low on coolant. Easy fix.

You may need to take off the top hose to the radiator and fill it up. Or you could try adding some through the turbo resevoir, and burping the lines.

Starting the car sometimes help cycle some of the coolant around, allowing you to add more. It may seem like you filled it, but its not full.

Don't let the full turbo resvoir fool you. Your heat will come right back too.

thanks for the help guys. i filled it up with maybe half or more of the bottle of coolant and let it idle with cap off. i saw it bubble a tiny bit and noticed the level dropping. so i kept adding accordingly. i kept checking the temp gauge. everything seemed fine. i let it idle for about 2-3 minutes before taking it out for a 5-6 minute drive. no change in the engine temp. and all while the heat was blowing nice HOT air.

just in time for the winter.

thanks again!

Nice. Check it again after driving it, and add more if needed.
