300 degree COOLANT

[Espen Hilde]

Thanks for a good and interesting breefing...I have tought in the same
lines as you describe.
A guy who makes diesel turbo conversions once told me that if I was brave I
could use some light viscosity syntetic oil as a coolant.I think this
aproche will suffer the same way as using pure PG.
