Hi.
Drained (some of) the coolant from my 85hp twinair today (actually a 500).
I'm flying blind with this engine, as there's no literature.
I wanted to flush it out with distilled water for a few days, but only got about 3.5 litres in, which means I left about 1.5 litres of coolant in.
I put the heater dial on full, and removed the cap off the expansion bottle, and opened the petcock.
There doesn't seem to be any bleed nipples in the system (??).
I've just looked at a parts diagram, and there may be a plug on the top of the rad, on the opposite side to the drain petcock.
Would removing this help?
Otherwise, does anyone know how to thoroughly empty the system?
Cheers in advance.
