Old Toyota Overheating Problem

[Rally Pack 2000]

Mums old Camry has had overheating problem for years but she is of that age where she wont have her licence for long and all she uses it for is to get to the shops and back  so the overheating problem doesnt really manifest itself cause its not running long enough but if the journey is for a few kms longer then it does. But after a few trips you have to top the radiator up.

Basically it dumps all its coolant into the overflow bottle and keeps doing that till the radiator is empty and it overheats. I just took that as clapped out engine sign which of course wasn't worth getting the engine repaired and just kept waiting for the end to come and the upset phone call. I took the car out myself the other day just to see how far it would go and it went 20kms or so which didn't seem too bad all thing considered but before the return journey rather than push my luck I went to top the radiator up and I noticed that the top radiator hose had completely collapsed. So there was the negative pressure there to draw the coolant back into the radiator from the overflow but it simple wasnt doing that and flattened the hose instead. That made me wonder if the engine isnt as far gone as I imagined and ignored it this whole time but instead there is just some small fault with the overflow system. I will replace the hose of course but Is there a valve in the lid of these things that draw the fluid into the bottle that is blocking the return of the fluid or something? Im feeling guilty now telling her every time she mentions the car to "get a new one" if its been a fixable fault all along.
