Suitable for 100 % Glycol and antifreeze agents.
All hoses which are exposed to the radiated heat from the exhaust
system have to be shielded in an appropriate way (i.e.: with a heat
resistant hose).
Instead of long hoses, aluminium pipes may be used (inner
diameter 25 mm (1")). These should come with a bead (1) to avoid
loose coolant hoses.
