|
|
I seem to recall seeing somewhere how to vent the cooling system to remove potential air bubbles but cant find it. I have been doing some engine runs while waiting for permission to test fly and it seems to be getting pretty warm - water to 120 C after around 20 mins at 2200 rpm and I wondered if there is air in the system or if that is normal.
Am I right in thinking you slip up the port side radiator connection rubber and drill a small hole on the rad flange?

Graeme
yes you are right, if memory serves it was referred to as "Nev's Orifice"
If the swirl pot is higher than the radiator you won't need it but it's awkward on a Classic

Graham, I have XS FWFD, and the rad is under the engine, and filler pot on top, so presumably I dont need to worry?
