Coolant issue
 

Hi all

I seem to be having a bit of a coolant issue on my v3 sti.

On doing the weekly levels check, I noticed today that the header tank level was slightly lower than normal. We're talking about 1/4 cups worth if that, but it is normally a bit higher than that.

I topped up the coolant (engine still stone cold at this point) and then tried burping the system. So with the engine running, cap off and heaters on, I squeezed the top rad hose. A few bubbles came out and as the temperature increased the level started to spill over, which I mopped up.

Am I right in thinking that this was probably an airlock in the system, hence the level being slightly lower? I pretty much seemed to mop up the same amount of coolant I topped it up with?

Forgot to add - the car doesn't overheat and it blows hot air no probelmo

cheers

keep a check on it if it keeps going down its going somewhere....
check pipes and clips to make sure there are no little leaks.
check the pressure cap too

if it gets worse then this stuff
