Hey fellas do you know what causes the problems in a cooling system? you can use special; litmus paper to measure the acid in the cooling system or you can go to harbour freight and in the garden section you can find a PH measuring probe and it will do the coolant in your system as well as the yard, your saliva. The problem is the sulfer in the fuel you need to run the vehicle. Sulfer will NOT burn, you can put a fire out with it. the cyl walls are pouris and with each combustion in the cyl a small bit of sulfer gets hammered into the wall eventually it will get into the water in the cooling system. Now chemistry 101 sulferic acid is made up from Water Heat & sulfer. I know this is a long story but there are no real lifetime coolant fluids. I have been checking both my gas and diesel vehicles for several years and using BG products cooling system condioner to bring PH back to slight alcaline I have stopped rust and aluminium radiaters from being ate up. Thanks Eric davis
