Hi all,

When i had a leaky rad i used radweld, now the rad is fixed i still have radweld in my system i can smell it and see it (it's turned my header tank brown ) how can i flush all the radweld out, i've tried with a hose pipe in the hoses but it wasn't powerful enough.

Thanks

 

The stuff will collect in the expansion tank as a congeled WHITE mess.
I use this stuff all the time as needed, just flush as you have, and cleaned out tank twice, about 1 + three months later clean as a whistle now.

Cheers mate, looks like i'll have to flush it through every couple of weeks or so
