collant flush -- how much dish soap to degrease?
 

I have searched quite a bit, and while I see several threads suggesting dish soap as a degreaser during a coolant flush, I cannot find one that suggests how MUCH to use. Any thoughts? I have already flushed my system of all (or most, anyway) coolant and am running water now, FWIW.

Apologies in advance if I have glossed over said information during my search!

I think tide is the preferred detergent.
dish soap may work, but laundry degreasing is best.

1/4 cup I believe... not sure though.
use google.com's advanced search and key in this website as the domain to search.

Shout for a 1979 240D
 

o Mix a 1 part of liquid Shout to 3 parts of water (0.879 gallons of Shout and 1.75 gallons of water and fill on a 240D system_____________________________

If you're going dish soap, use dishwasher soap.
Non-sudsing is what you want.

A cup of Liquid Tide worked well for me.

You successfully De-grease ...Use the recommended citric acid flush to help
remove mineral scale.

I have that too... I just saw that a 2-step procedure is recommended by many, so I just needed to know how much detergent to use.

Thanks for the advice, all!

I would be carefull of a flush on a mb with an evil servo ,I have always used tide detergent when flushing all my cars ,but a 79 mb 300d I owned didnt like it to much ,it was the heater servo that bit the dust ,a crack made it worthless .Fortunately I remember seeing one at a junkyard days before,I really lucked out since they can be $700.or more.

Consider using detergent for a front loading washing machine. Tide, ALL and Gain all make the stuff. The advantage is the soap is designed to create less suds then the usual top loading machine soap.

I've heard this brew also, never done it. Take out thermostat, idle for a little while, let cool, drain flush with water.
