How to flush out the radiator after oil is in it
 

My truck is blowing oil in the radiator. I'm getting it fixed tomarrow. But how do you do a flush that will clean the oil residue out? Thanks

water and dish soap ,run to temp and drain then flush with water till all the suds are gone

so i would use something like joy detergent

Use liquid dish washer soap, it doesn't foam.

so I would use something like Joy or Dawn

Yea I have heard of people using mean green and restor radaror flush. You should think of replacing all your radiator hoses my buddy is a master Powerstroke mechanic and he says if you don't that the hoses will break down and fail due to the oil. But I don't know.

cascade works well - low suds.

I have also heard of using the simple green.

Add some Calgon to soften the water. Detergent works just as well with less suds.

Good luck.

I have done all those things , and I still cant get the sludge out. Any ideas?

Simple Green HD is what a Tech I know uses. It is not easy! His recommendation is to replace all rubber components in the coolant system as well as the radiator and the heater core after flushing as much out as possible.
