Coolant Flush
« on: 10 June 2015, 19:03:23 »

Hi guys, is there a recommended coolant flush to use for cleaning out the cooling system after replacing the Oil Cooler, a lot of the stuff for sale states you must poor it into the radiator but I need to clean the expansion tank ect so would want something I can poor into there?

As always your superior knowledge is very much appreciated :y

Firstly, do about 20+ flushes with water.

Remove bits you can, flush under tap.

Good luck!

Do you need a coolant flush then or is it just water?

Oh, sorry...didn't read the piece about oil cooler failure.

I simply used washing powder.

Thanks for the advice guys, I'll get some dishwasher liquid and flush it out a good 30+ times no doubt and hopefully it will clean out the gunky oil in the pipes.

Screenwash worked quite well as well ::), but I'd flush the bulk out with water before moving on to chemical options, so the chemical options stand a chance of working.

omegatoy used to suggest cap of bleach, with engine on idle up to temp. Helps break the oil down

Better to use dishwasher tablets. Put 2 or 3 in a small bucket with warm water & disolve them . Then add this to the header tank  filling the system as best you can ,  let it soak overnight , then flush out with hose . You will need to do this a lot of times .  Don't know about dishwasher liquid   . . . but I do know that dishwasher tablets work . HTH  :y

I think we went through half a pack of .. I think they were Finish Powerball.

Fed a few into the header tank, ran till hot, span the cap off (dodge the volcano of sludgy water), drain, fill, repeat..
