Auto Tester Radiator Flush Kit (AF-KIT) removes the rust and dirty antifreeze/coolant in your car's cooling system to avoid overheating, radiator failure and engine damage.
This kit includes: one deflector, one coupler, two horse clamps, three flushing tees (1/2", 5/8", 3/4").
1. Flush Preparation and Tee Attachment
Check the engine to make sure it is no longer hot. Loosen the radiator cap to release any pressure still left, and then retighten.
Place a pan or bucket under the radiator plug beneath the car to catch the old antifreeze.
Splice the "Flush Tee" to the heater inlet hose.
2. Attach the Coupler and Back Washing
Remove the cap covering the tee as well as the radiator cap. Attach a coupler to the flushing tee to prevent backwash.
Flush with tap water until it runs clear.
