You can get cooling bleed kits that work quite well, or attach a hose to the heater inlet and run hose water through the system with the heater on and the engine running. I've not been that fussy with mine though, just run a flush and then get as much as I can out, leave it for the night and fill up the next day, run for a bit with the cap off and top up as required.

I flushed the system about 6 times, ensuring heater was on full and letting he engine warm up till the thermostat opened. 4 times with hose water 1 time with coolant flush 1 time with distilled water Finally I drained the distilled water and poured in 5-5.5L red conc. toyota coolant and topped the system off with more distilled water. Still not satisfied with the colour of the water..or maybe I am just imagining things

try removing the thermostat and then flushing. Did you do the reverse flush? bring car up to temp, and Wire the heater open. shut car off. reverse flush with hose.

While we are on the subject of the cooling system - does anyone see any issues with permanently bypassing the heater vacuum valve relay?
Mine has been behaving erratically - at first I thought because the heater radiator was clogged, but putting the hose on through it, it flows clear and fast, then I thought the valve itself might be sticking, so I pulled it off - its working fine when I suck on it - so I bypassed the relay with a direct vacuum line to the valve, and now it's fine.
Guessing either the relay is sticking, or I just had an air bubble trapped in the heater radiator that putting the hose on it has dislodged.
Either way, I'm fed up with mucking around with it (spent about 2 hours mucking around with it yesterday) and it's working as I want it to now, so just thinking should I leave it like that, or check the circuit, find a new relay etc?
As far as I can tell the only penalty is the car might take a fraction longer to come up to temperature with water constantly circulating in the heater core, and as I live in a very mild climate, I'm not bothered by that.

Well, looks like all my problems may be just due to sludge, despite having just flushed it out in August it was still full of crud. Hopefully the chemical flush I'm running now will sort it out properly - in any case I've returned the vacuum lines to their normal positions.
