Knowledgeable Trollers, need a bit of advice. I've had a search on tappacrap but alas can't find what I'm looking for
After I drop both hoses how do I get the rest of the system drained block/head etc??? Do I need to run the engine??
Tap, Tap.......Who's there?
IF YA DONT GET STUCK YA AINT TRYIN HARD ENOUGH........OR YA TOOK THE CHICKEN TRACK

Used to turn the key for a quick run on last 4b, did no harm, quick squirt with hose.
Don't think you'll get the lot out though.

Are you trying to drain it dry or just get rid of the old coolant before a freshen up?
You can run the hose through it to flush and remove all old coolant leaving only a small amount of fresh water in there afterwards, then add new coolant and I'd say the small amount of fresh water in there won't be enough to dilute the coolant. Or if your mixing it yourself, just make it a poofteenth stronger....
Tap, crackle, pop
Hello from Under Down Under!
When i dumped the radiator hoses it seemed it only dumped what was in the radiator ie only took 5ltrs to fill and the gregory manual says coolant system holds 17 ltrs or something like that

Pretty sure if you turn the heater to the on position, that will help to drain from the hoses in there. I have a backflush tool that I bought to drop my coolant and reverse flush. I think it was about $80 from memory, but a lot of people make their own. Even running the hose through will help to push the old coolant out.
Edit-Also what lucas said.

Beauty I'll give it a go. Only the radiator dumped so I was wondering if there could be an air lock but that heater could be the issue. An
I better off doin it hot? Bare in mind what I did to my lawn with hot sump oil it's still fubar there

I don't think it really matters if you do it hot or cold mate, others may have differeing opinions. The other thing that can release an airlock is a bleed screw. Not too sure which motor you have, I have the 2.8TD and there is a rubber cap on one of the heater hoses up near the firewall on the drivers side, once that is off it releases the air lock on mine. I think the tb42's have one on the thermostat housing. Not to sure about the TD42's though.
Oh and the coolant will probably eat your lawn regardless mate, so try and catch as much as you can in a bucket or drum or sumink!I have one of those $5 flexible buckets from Supercheap which i find awesome for dropping the fluids out.

Growlers,
It would probably pay to remove the top thermo housing and pull out the thermo as well, this will also create an airlock as the thermostat will be closed if the coolant is cold.

As above in the pic and also to removing the thermostat. You can run the hose through different sections for example place hose in thermostat house your hand over water pump intake and let the water push out the block drain and so on and so forth.
