as title, my coolant level keeps changing, as im driving it will be empty then full and does it a few times, was wondering what this could be??
Does it fill back up through the exit pipe, would suggest that the input pipe to the tank is blocked - maybe the ball valve thing that should rattle when you squese the pipes is stuck? (Not sure I know what I am talking about there, I've never looked at it properly.)nar not had too fill it up, the tank will be empty and if i unscrew cap it fills bk up
Ahh, it's called a jiggle valve - couldn't remember that yesterday.yea fills back up through the exit pipe, where is the ball value locate do u know?
