Thread: Coolant Goop? What now.

Try flushing with a hose and see if you get lumps coming out or just liquid coolant keep it up till water is clear, or go to a radiatior repair shop and ask if they have a flushing agent that will do the job, Regards Frank.

i had to clean mine out on the handbrkes car after the auto trans coolerpipe
in the radiator split.....

now this a the best cooling system mess i have ever seen......


i flushed it all using CT14.....a detergent for trucks i think.....
remove the thermostat......and add half a litre of the stuff in the water.....
then run the engine and let it circulate and break down the mud.......
then flush the cooling system with clean water.......


you may need to repeat the procedure till its all clean......





it worked a treat in the falcon.........

I flushed with the hose and get no lumps. The water continues to come out with a green tint though so I think a lot of it is dissolving, so ill keep on flushing, But....

I soaked some of the harder stuff, which was stuck to the thermostat, in a cup of water last night and it is still just as hard this morning and no sign of it coming away without assistance.

Ill try the cleaner and see how it goes.

cheers

that's silicate dropout, happens when the coolant gets a bit older and isn't changed.
Run an alkaline based cooling system cleaner like Tectalloy 'MukOut' through it, then use the required coolant.

If you were to use an OAT coolant you use an acid based cleaner first.

This is the recommendation from one of the chemists/tech blokes at Tectalloy coolants.
