Radiator problem

on: April 22, 2006, 19:25:03 PM

My friend has a 4-stroke dirtbike with watercooling. The channels in the radiors (one on each side) is clogged with some sort of green oxide.
Does anyone know something that can disolve it ? He has tried oxalic acid.

There are plenty of generic radiator flushes available - Id give one of them a go

Is the clogging on the outside? If so, theres a leak in that radiator !

He has tried that of course. This oxide seems hard to solve.

what about some of this rust eater stuff you can get ?

that should react with the oxygen in the oxide and then you can just flush it out ?

carefull tho, some of these rust eaters leave a solid lump, where you want a goo left

Dont forget that the green oxide has to come from somewhere. Could mean some nasty damage.

green normally means copper, tho copper oxide is blue.... not sure where/why it goes green, its normally caused by weathering

The radiator is aluminium but the cylinders has magnesium in them(to save weight), a bit to much it reacts badly with water so he had some leeks so he just leek stoppers two different kinds so the oxide (the light green stuff clogging his radiators) is a mixture of all that

Copper oxide is green, copper carbonate is blue iirc from a level chemistry

lol tbh... buy a new one

Then you can have fun watching the magnesium go PPPPOOOOFFF!! when you throw the radiator on an open fire.
