Folks, was working on the cabby this morning and noticed that she when the engine is running and she starts to warn up coolant is pissing out of the expansion cap.

I checked it and its nice and tight, and both washers are present but still pissing coolant out !

Could this just be a case that the expansion tank is knackered and I need a new one?

cheers

I would suggest a new cap first, and examine the bottle for cracks around the neck.

Quite unlikely to be the bottle itself though
