96 Need Advice On Radiator Problem

:banghead: I HAVE A 96 MONTE LS AND I REPLACE THE DEX COOLENT WITH REGULAR COOLENT. I NOTICE AFTER AWHILE THAT THE GAUGE WAS READING A LITTLE HOT. SO I CHECKED THE COOLENT, THIS IS AFTER THE FACT THAT A MONTH HAS GONE BYE SINCE I PUT IT IN. WHEN I CHECKED THE RADIATOR I NOTICED THERE WAS A SLIME OR FILM ON THE OTTER LAYER INSIDE THE RADIATOR.
:confused: MY QUESTION IS HOW OR WHAT CAN I DO TO CLEAN IT OUT. IS THE SOMETHING I CAN FLUSH IN THERE OR WHAT. CAN SOMEONE PLEASE HEEELLLLP ME?

The Thing You Could Do Is Buy A Flush Kit And Flush It First Then Add Water And What Ever The Flush Kit Comes With Follow The Instructions . Then Add The Dex-cool. Then Run It For About A Week Then Drain And New Dex-cool.
