Professionally backflushes cooling systems of most cars and light trucks on the road today. Includes flush & fill tee, back flow preventer, hose clamps & splash deflector tube. One kit fits any light truck or car. Easily installs antifreeze/coolant in minutes. Rust and dirty coolant that circulates in your car's cooling system can lead to a clogged radiator, resulting in overheating and engine damage. Draining the radiator alone does not sufficiently remove old coolant, as the radiator may contain 40% or less of the coolant. The Prestone® Flush 'N Fill Kit allows you to professionally flush the complete cooling system, not just the radiator, in one easy process.
