Water Pumps and Cooling System

A while back Honda was running into a rash of failed water pumps and blown out water jacket gaskets. After calling in about two hundred of the failed water pumps and not finding out why. They then asked Honda dealer to call them directly when they had received a Honda with a failed water pump or blown out water jacket gaskets. Well, after about another two hundred on site with water pumps still on the bikes and still not finding out what was up they were completely stumped. They then found that the water pump or water jackets that had failed had also come from owners that had serviced their own bike and the cooling system. They then started asking what coolant was reintroduced back into the cooling system and it was found out to be auto coolant. It was then found that auto coolant has silica in it to actually help clean out any cooling system deposit that could be acquired in the cooling system of the cars cooling system. It was at that time found that the silica that was meant to help blow out/flush out the build ups in the cooling system of the auto was actually destroying the cooling systems of the bikes. Once this was discovered and a bulletin was sent out that this was indeed the cause of the water pump and water jacket gasket failure the problem for the most part went away.... That is why you will now be asked if you have a failed water pump or water jacket gasket and you changed your own coolant and did you put "auto coolant" in the bike or "Honda coolant". If it is found that auto coolant has be reintroduced into the coolant system it will void your water pump and water jacket gasket warranty. You will also now find this warning in your new bike owners manual......

Again, the 1500's blaze the trail........
