Old Volvos (& many other cars) use pressurized expansion tanks for the 
rad. & you can see at a glance where the coolant level is during preflight.

Discarded small fire extinguisher bottles can work well & they are 
probably free from most fire protection companies. Dryer bottles from 
auto a/c systems will work too.
