Drained the Evans coolant and replaced it with Nulon llr, with the air temperature about 32 the cylinder head temp was 110 at cruise but got to 125 on climb outand spat a lot out of the plastic bottle, oil temp was 100, think I will have to run the evans, has any one made any baffles for a gazelle to try and force more air through the radiator, or fitted another radiator or moved it to a position where it can get more air flow rather than at the back of the motor where it hardly gets any air, I don't know what skyfox was thinking mounting where they did, open to suggestions cheers Keith.
