    Prestone® Triple Seal Protection Head Gasket Stop Leak made with DuPont™ Kevlar® resin

    Prestone Triple Seal Protection Head Gasket Stop Leak made with DuPont Kevlar® resin is the latest evolution from the leader in cooling system products. Simply add Head Gasket Stop Leak to any color of antifreeze/coolant and Prestone's proprietary Triple Seal Protection begins to seek out and seal leaks. It stops cooling system leaks fast without blocking or corroding the cooling system. Do-it-yourselfers can now affordably fix head gasket leaks and potentially avoid expensive engine repairs without visiting a mechanic.

    The Power of Triple Seal Protection:

    • Effervescent beads quickly break down and go to the source of the leak
    • DuPont Kevlar® resin forms a fibrous web that bind to metals
    • An acrylic polymer hardens and secures the seal and makes it permanent

  • Prestone® Radiator Flush + Cleaner

    Prestone® Radiator Flush + Cleaner is a 2-in-1 formula designed for light flushing and heavy-duty cleaning for cooling systems to help prevent overheating, the #1 cause of engine failure.

    1. With engine off and cool, remove radiator cap.* Drain radiator then close drain cock.

    2. Pour entire contents of Prestone® Super Radiator Flush into radiator and fill with water. For systems larger than 12 quarts, use two bottles.

    3. Run engine with heater on highest temperature setting for 10-minutes after reaching normal operating temperature. 

    4. With engine off and cool, remove radiator cap, drain radiator, and close drain cock. Refill with water and replace radiator cap to fully closed position. Repeat step #3.

    5. Stop engine and allow to cool. Remove radiator cap, drain system and close drain cock. Add enough recommended coolant to achieve a 50% - 70% concentration. Top off radiator with water. Replace radiator cap to fully closed position. Run engine for 20 minutes to mix coolant/water.

    6. If equipped with a non-pressurized coolant reservoir, rinse, drain, and refill with a 50% - 70% solution of the coolant and water.

    CAUTION: MAY IRRITATE EYES. Do not get in eyes. KEEP OUT OF REACH OF CHILDREN. FIRST-AID TREATMENT: Contains Sodium Citrate. If in eyes, rinse with water for 15 minutes. If on skin, rinse well with water. If swallowed, call a poison control center or doctor immediately. Do NOT induce vomiting.

    This premium formulation is designed to remove heavy rust and scale deposits in neglected cooling systems. These deposits can dramatically restrict coolant flow and reduce heat transfer, which may lead to possible overheating, breakdown, or costly repair. A super-chelating additive effectively removes heavy deposits by drawing metal oxides into the solution. Though strong enough to help restore maximum cooling system efficiency, this non-toxic, non-acidic product is easy-to-use and safe for all cooling system metals.
