Engine Water Jacket Cleaning

[Colonel]

The cooling jacket on my engine is in visibly very poor condition and full of rust products. Is there a method to clean this without stripping the motor? I have removed it from the car.


The material is thick and metallic. It tore up my water pump. The engine runs decent but overheats immediately. Temp inlet to radiator off the chart. Installed new rad and hoses so they were not the problem.


All thoughts appreciated.
