Thread: oil in coolant.......

Whenever we fail and oil cooler on heavy earthmoving gear we use plain of finish dishwasher powder. Works a treat and flushes out very easily once the system is clean. Just add the powder. Run the car to temp and drop the coolant. Repaet until there oil sludge is gone.

Steer clear of commercial cooling system cleaners as they tend to cause more harm than good.

G`day ,

Hook your hose up to the hot water tap , put some dishwasing liquid in it , which will foam .

The heat of the water with the liquid will break down the mix .

The bubbles will help to get into odd places .

Reverse flush the block with the stat out , same with the rad .

It will be on going but as you know the oil will settle ontop of the water , the main reason to reverse and you`ll find different rates of pressure will be required , one rate may mix it all up and another may push the **** out .

Cheers

With mine I just used water. Ran the vehicle up to temp and then disconnected a hose and plugged the garden hose up and ran it again till the water was clear. I did this several times and it worked. It definatly needed to be hot to get the sludge out.

I have done this many many times on engines with ally water pumps and timing covers and have never had a drama. We generally use a box in a 200ltr system so a tea spoon or two would be all thats required in a 10ltr(ish) system

concentrations that small might be ok. But a table spoon in a laundry sink full is disastrous (don't ask me how I know...)

Did you leave the parts submerged in the solution? What got eaten?
