You checked the water level? Might be air in the system try running it with the radiator lid of and giving all the pipes a good old squeeze

If you put the filler cap on when its hot, the system cools down & 'sucks' the hoses in? Try easing the cap off when cold & listen for the system sucking air in.

cheers all, checked the water this morning..none left in the reservoir tank?

Added some and opened the air release bolt and went on my way.. hoses still inflated when i got back..begs the question where the heck did the coolant go?

and how come a) engine does over heat b) what can I do to fix it?

I had the flat hose problem. It turned out to be a blocked overflow pipe. The thin one just under the rad cap. Disconnect it from both ends and blow the crud out.
