Radiator flush

[TriumphDriver]

Mercedes Benz recommend citric acid flush. I've done it before on my 6.9 with no ill effects.

so: coke with lemon then?

Not quite, it's citric acid in powder form. You can get it directly from MB and it will cost you an arm and leg, or you can go to your local ethnic food store (middle eastern or Indian) and buy from there as they usually sell it in the spice isle.

The way they recommend to do it is to remove the thermostat and drain the radiator. Then add the amount of citric acid / water mix back into the car and run for about 25 minutes with the heater on. Then wait for it to cool and drain.

Looking at the inside of the hoses after the flush, they looked as clean as they would look if they were new.

There's an idea - a cup of curry powder, run it for an hour or two - job done!

Well, it works on my insides.....

Cool, go ahead and try that, and let me know how it works out

I think you have to add beer before the curry for best effect.
