    It doesn't get any easier than pour(flow) and go.
    No mixing, no guessing how much water to add.

                      Can this be used by itself or does it have to be mixed with existing fluid? For example, can I fill the entire radiator with nothing but prediluted Antifreeze?

                        Hi Rodney, glad to help you! You need to drain the system if it just has water in it. Then refill the whole cooling system with the Prestone 50/50 Ready-To-Use Prediluted Extended Life Antifreeze/Coolant. Instructions: For Vehicles with Expansion Tank - With the engine cold, remove the pressure cap and fill tank with Prestone 50/50 Ready-To-Use Prediluted Extended Life Antifreeze/Coolant to cold line. Replace cap securely. For Vehicles with Recovery Bottle and Pressure Cap on Radiator - With the engine cold, remove the radiator cap and add Prestone 50/50 Ready-To-Use Prediluted Extended Life Antifreeze/Coolant to within 1 inch of the top of radiator cap. Top off recovery bottle to "cold" fill line. Note: Check fluid level periodically and owner's manual for any other recommendations for antifreeze usage.

This Prestone 50/50 Ready-to-Use Prediluted Extended Life Antifreeze/Coolant - Part No. AF2100 does not contain any of the compounds that you mentioned (technically, it does contain trace amounts of phosphates, but nowhere near the amount that an OEM is concerned about, you can still use it in any application that requires a phosphate free coolant).

                        A:

                        I'm happy to help, Jim! Prestone 50/50 Ready-to-Use Prediluted Extended Life Antifreeze/Coolant (Part No. AF2100) is designed to be compatible with aluminum radiators. It contains 2-ethyl hexanoic acid, which is typically found in Dex-Cool. Peak Long Life Antifreeze/Coolant (Part No. PRA003) or Peak Long Life 50/50 Prediluted Antifreeze/Coolant (Part No. PRA053) do not contain this chemical and is also compatible with aluminum radiators.

                        I suggest purchasing a coolant that is compatible with the original coolant that was in your 1999 Suzuki Intruder 800. If you could please provide the year, make, model and engine size of your motorcycle, we may be able to locate a coolant that meets the original equipment specifications.

                      Can this product (Prestone 50/50 Ready-to-Use Prediluted Extended Life Antifreeze/Coolant- All Makes and Models) be used in 2003 Toyota Avalon XLS? Is it okay to top the radiator off with this coolant or do we have to flush the radiator first?

                      Thanks.
