I am getting ready to flush my radiator and change the fluid but before I do that I wanted to see what info I could find on the boards. The orginal radiator fluid in my car is green. My mechanic told me to get some radiaotr flush detergent to flush the radiator with and wanted to switch it over to the new orange coolant(I think made by Prestone). He wants me to make sure that I have pretty strong coolant in the car since I run her hard ever now and then. Now some people have said to stick with just the factory Honda radiator fluid. I have a bottle of redline waterwetter sitting in my house but I wanted to know what you guys think. Should I switch to the orange stuff, factory honda radiator fluid(which I never knew they had), or just the regular stuff??
