Hi,

07/07 WRX STi Spec D.

I'd like to check the water in the tank (nearest the turbo / TMIC). I'll do this when stone cold, but roughly where should the water level be?

Up to the brim? Just below the neck?
Won't get an air lock by checking it will I?


There is plenty of water / coolant in the non pressurised tank by the rad - it's on max when cold.

Many thanks.

 

You won't get air in the system, just make sure it's cold & the level should sit just on the rim, at the bottom of the cap.

 

Thank you, that's all I needed to know.
