Was watching discovery channel - I think - re-doing an engine and then replacing the normal coolant (which contains water) with a waterless coolant.
Firstly no water = no rust
Secondly boiling point is no longer 100 degrees celcius but something like 180.
Guy let the motor get up to working temperature and then took the radiator cap of while the motor was running


See that Silverton radiators stock it as - Evans High Performance Coolants.
Opinions??????
