Excess Fluid In The Coolant Reserve Tank

[EOLIVER]

This afternoon, while changing my MAF relays, I noted that cooland had pooled up on top of the colland recovery tank. I opened the radiator cap and noted that the coolant level was low. There are no coolant leaks that I can see, but I have noticed that it take the colling temp longer to register upon startup. Is this a sign of something going bad or is this a ntural thing as the car sits garaged on the wekends after a long weeks drive?

Low/High coolant

You probably have a bad pressure cap (lets coolant out but lets air back in) or a hole/crack in the hose/fittings between the filling reservoir (black pressure tank) and the recovery tank.

Thanks everyone, it was in fact a bad radiator cap.
