This way the oil in the coolant is diluted to less than 5%.

Here is another trick... If you drained from the heat exchanger by following the coolant flush DIY.
Then after the coolant drains.
Squeeze the rad hose going from rad to the OFH.
Squeeze and release it repeatedly.
Listen to how much more coolant comes out.

Inspect each drain.
Make sure to do a purge after each refill.

Oil you may not have to drain again and again....cause our oil heats past 100 degrees Celsius.
And any water will evaporate.
This is normal for our cars as inherently the oil condenses water during cool down.
Just change it at 1k or less, but should be ok.

Simply Green is your friend around the engine bay to safely dilute the oil and then can be washed off.

Your ok...
IMO.

Thanks, I will be doing a few flushes with water through the coolant lines.

I bought some simply green, however before that I'd used a hell of a lot of aerosol degreaser to clean up the engine bay.

Do you think the pulley bearings and accessory belt will have been compromised by all the degreaser sprayed around in there?

I've also got some new coolant hoses coming too, as I think the degreaser tends to eat the rubber? After I hose it down, the rubber hoses still feel sticky. I wonder if that is normal?
