Technical Radiator rust! SOS

Hello man.

I can only find oxalic acid in powder form. How do mix it ? Can I do it with distilled water ?

 

Thermo-Cure by Evaporust.Worked great for me.

 

Oxalic acid dissolves in water, all types of water.

Whatever process you use, a filter or ***** hose is needed. All the stuff you're breaking loose will go thru your water pump. Leave the heater core for last until the system is clean, loop the hoses to byp*** until then.

 

Thanks Indy. But what part should the filter go ? Return hose to the radiator ? Pump input hose ?
Btw. Is the ***** hose really about using a ***** as a filter ?
