Cooling system full of oil whats the best for removal of oil.

Thanks.

pressure washer, car shampoo and PLENTY of patience.

you need a non foaming detergent or ideally a solvent/engine cleaner but you need to be disposing of both properly. it doesnt really matter what you use to remove the oil as long as you fully rinse the system afterwards (and you dont use something that will eat rubber o-rings and hoses)

Thanks Rich,

no problem... glad to help
