I've had the "low coolant" symbol come up for a split second tonight coming home, mostly upon either strong acceleration or cornering, and upon checking, have seen that the cap has a pool of coolant around it, and that it does nt sit flush. To be clear, it is not cross threaded, nor twisted, it's just when fully on, the flat flange that fills the void recess in the expansion tank that the cap screws down into, sits at an angle.
Are these caps supposed to do this, is seems to be square on the tank itself when screwed down, just the flat dish section sits up.
The rest of the coolant system seems ok, just leaking a little fluid.
Does anyone know if the expansion tank/cap suffer age related maladies, or if it's just one of those things (Or, heaven forbid, the sign off something more serious)?
Thanks
Rob
PS I'll be replacing it anyway, just in case, just want to know if it needs the whole expansion tank or just the cap.
