Radiator problems...

[darrsi]

I reckon the actual problem was that the original poster had been trying to refill his cooling system at the expansion tank and is too embarrassed to admit!...





(that's what I did 3months ago because I'm an idiot and thought that's what the Haynes manual said)

As long as the system was air tight that would theoretically work.
It would get sucked back into the engine when it cooled down.
BUT, the fact it may be empty in the first place would've meant all was not well.
