Hi Patrick

The radiator should not be filled to the top. Fill it only to about an 
inch from the top to allow for the water expansion.

This was the norm before expansion tanks were used. My Silverstone ran 
this way all through the highs and lows of Italy in 32 deg plus days.

Regards

You are correct.  As long as the overflow tube is tight/ with clamp ?/ the
over flow coolant will be sucked back into the radiator as the system
cools. the correct cap is essental. Aloha. Jim

It will work fine on an unpressurised system. No real difference with a 
pressurised system.
However the radiator cap needs to be absolutely airtight. You would 
probably need an overflow bottle of minimum 2 litres. The hose in the 
overflow bottle should end near the bottom or the overflow bottle should 
have an inlet pipe at the bottom. It should also have a vent in the cover.
Fill the bottle halfway and keep replenishing for the first few weeks as 
fluid will be drawn back into the radiator until it is full to the brim.

Patrick--

The system will draw coolant back into the system from the expansion tank
only if the end of the hose is submerged in coolant, either because it
enters the tank from the bottom or from the top in which case, as Kimo
points out, the hose clamps must be tight so that the vacuum created within
the radiator is preserved in order to draw liquid.

Yes, a sealed cap which includes those with the button vent that
essentially pulls in and seals when there is a vacuum in the system below
it.

                                            tank separately in front of
                                            the cap. Being unpressurised
                                            there is nothing to stop the
                                            hot and expanded coolant
                                            from exiting via the
                                            overflow pipe.</span></p>
                                        <p class="MsoNormal"><span></span> </p>
                                        <p class="MsoNormal"><span>I am
                                            thinking of fitting a
                                            coolant expansion bottle but
                                            am wondering if this will
                                            work on an unpressurised
                                            system. It seems to me that
                                            it should not make any
                                            difference, because if the
                                            coolant cannot escape to the
                                            outside world when it
                                            expands then it should flow
                                            back into the radiator once
                                            it cools.</span></p>
