How many ounces of dishwasher to clean oil in cooling system

Hello Guys

I have a 2008 Volvo XC90 3.2 and the coolant reservoir was full of oil sludge.

A couple of weeks ago I replace the Water to Oil cooler because it was cracked and it was allowing oil to pass to the cooling system.

We flush with water all the cooling system until clear water come out from the radiator.

A week later there is still a little oil floating in the water and grease stuck to the walls of the coolant reservoir. Check my pic.

I have flush again with water, but there is still oil floating and also is sticking to the walls of the coolant reservoir
I want to clean the entire system very well, before adding the coolant.

I have read that many people use liquid dishwasher to clean up the remaining oil residue.

How many ounces of liquid dishwasher should I add to the coolant reservoir to completely clean the residual oil that remains in the cooling system?

Thx for your time and help

Isaac

A long time ago I was recommended to put one dishwasher tablet in mine for the same reason by a mechanic. He swore blind to me that's what he did. never tried it and just kept flushing till it went. it took a while.
The problem I saw was that the detergents in Dishwashers will eat away at any alloys try putting an aluminium pan in your dish washer and you will see what I mean.

Put the dishwasher on an extremely high heat & it will corrode aluminium a bit quicker. Procrastination, mankind's greatest labour saving device!

Rather than pulling the reservoir out why not syphon the oil out, without getting a mouthful! Procrastination, mankind's greatest labour saving device!

You need a liquid pH-neutral non-foaming detergent - this should fit the bill:

Correction; having now checked the MSDS for this product, it is NOT suitable for aluminium - it contains sodium hydroxide!!

Apologies for the wrong info.

If not, just wash out the reservoir with the dishsoap and flush the heck out of the entire system a few times after a few drives.
