Extended Life Coolant. There a 4 or 5 brands. Walmart stocks Peak Final Charge which is a very good coolant. Try your nearest Diesel Truck Shop. Large Truck Stops. Don't bother with worthless AZ or O'Reillys.=Worthless. Do a search via google on ELC coolants.
I researched the ELC coolant for awhile, and after talking with Mr. Gooch: It was a no brainer. Plus After the addition of a Coolant Filter, I basically tripled the life of my water pump. I just change the filter once a yr. Usually the 1st of Jan. Money Very Well Spent.
