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
Alex
