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

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?

[Field Marshal Dr. Opti]

I just run the hose with the engine running keeping a beady eye on the level.

[Field Marshal Dr. Opti]

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

I simply used washing powder.

Best stuff for flushing system after oil cooler failure is dishwasher tablets the liquid ones,or use dishwasher liquid.

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.

Not dishwaher fluid, dishwasher tablets... Specifically the ones Aaron used as they work

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.

[biggriffin]

Couple bottles of distilled(white) vinegar properly be as good.

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

Don't no which one's Aron used but I will look for liquid tablets and go with that idea after a good few water flushes.

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

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..

That's the ticket... Still took twenty plus goes though

Brutal but effective
