Hi Jon,
Regarding the heat take off from the radiators, I installed mod 10986 where a
door
in the aluminium air flow ducting opens into the airflow coming through the
water radiator and directs it into the cabin via a scat hose. It works, but
it's not very effective when it's getting towards zero degrees. In hindsight I
wish I'd gone with the approach of taking the air via a jacket around one of
the exhaust pipes like most aircraft appear to do.
Regarding cooling, I lowered my water radiator so there is practically no gap
between
it and the cowl. I also installed an oil thermostat. That combination provides
me with better cooling on hot days and seems to be fine in winter. I flew
at 9500' on the way back from Belfast a few weeks ago. It was -12 outside,
but my oil temp was 85 and water 65.
I hope you solve your problem.
Regards
Carl
