then i put the plug back in the bottom hose and let it flow out the expansion tank......

i then removed the drain plug again......turned the hose off and allowed it all to drain.....
then repeated untill there was only clean water coming out......and drained it all again.....


then i put the drain plug back in......refitted the heater hose.....removed the top bleed plug.....and poured in 5 litres
of nulon red long life coolant with OAT from supercrap.......and topped with water........

then started and allowed to reach normal temp.....while topping up the tank......when air stopped coming from the bleed screw i closed it.....

then i let it cool and rechecked the level before going for a run......once everything was ok.....i turned the heater off.......

yeh, did all that, mixed with rain water(I made it rain as I needed some),still got no idea if its the right coolant, dont really care nomore, i think a holden 186 will fit.

Defender zook - great info - thanks for the post. I will follow your wise advise for sure. Important point about running the heater to make sure that everything is well flushed.

any time guys.....i would have posted this sooner but i was away for a week.....
only just read it.....

its not a hard job......it just takes a bit of time to do it properly.....
if you were to take it in to a mechanic to have it done.......most would just rush the job to save time....

if you do it yourself you know its done.....

how many time a year do you change the coolant . I blew a rad and replaced it for $900 . May be if i had changed the coolant more offen I could drive further As you may gather I am new at this disco td5 game

The OAT coolant has a 5 year life span. So change it at least every 5 years.

Not sure if it will work on the Td5, but I have on previous cars run fresh water from the hose into the top of the block at low pressure. This will reverse flush the cooling system, without damaging the thermostat. Keep the water flowing until it runs clear. Have also seen attachments to plug into an air compressor to flush with pressure.
