When the radiator is empty, inject water into the bottom tank so that the sediment is washed out through the top tank water pipe. Then remove the filler cap and repeat the washing process. The object of this procedure is to apply strong caustic solution to the top portion of the matrix and afterwards wash out so that the sediment is washed away from the matrix instead of into it. mt Hm.{Capt.
