the search does not seem to be working to well

have a look at this thread, george130 indicated that green coolant was one factor in the issues he was having 'i think'

you should buy some marked OAT (organic acid technology) but not marked "ethylene glycol"

Well of all the kinds to choose, I chose the green ethylene glycol.............

I assume as i have not yet run it in I will be fine to flush and try again with some OAT stuff?

Man, knew it was all going too well last night

this is getting way too confusing, the stuff i got is 95% ethylene glycol and is also marked "Long life Organic Technology" I'm getting sick and tired of this BS, might just buy a NORMAL 4Wd.

AND its RED!!

I am pretty sure the Castrol coolant we have here is marked as such. I will check...

Yep, also contains Denatonium Benzoate or some such thing.

which is probably the bittering agent. So the Castrol one you guys use is 95% Ethylene Glycol AND has Long life organic Technology (LOT) but Doesnt say (OAT). LOTS of OAT, mite goin make a bowl of Porridge, its all too hard.

okay guys as long as it is OAT it will be fine. If not at the best in 12 months time I can send you the contacts to a guy who can rebuild your head even though all the mechanics will tell you you need a new one.

The mega flush advise was if you have the wrong stuff in or don't know.
My comment about how I do it was after finding the best pipe in the maze on my beast. The pip system in mine is not standard.

Sounds like you have managed to sort it anyway.

to flush the Td5 cooling system.....

i turned on the heater.......removed one of the heater hoses under the bonnet....
removed the drain plug off the bottom rad hose and removed the lid off the expansion tank.......

then i plugged the garden hose into the heater hose and let it flow.......and flow.....and flow......

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.......
