- If equiped with a non-pressurized coolant reservoir, rinse, drain, and refill with a 50-70% solution of coolant and water. NEVER SYPHON BY MOUTH.
* The cap on newer vehicles may be located on a remote, pressurized overflow reservoir. Follow instructions given for radiators, but add product and coolant to reservoir. Much longer running time may be needed to introduce product into system.
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 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.

Super Radiator Sealer
Prestone® Super Radiator Sealer’s special formula helps seal larger size leaks.
- Shake well to ensure uniform distribution of active ingredients.
- With engine off and cool, add entire contents to overflow tank or radiator.
- Replace radiator cap and run engine to mix thoroughly.
Super Radiator Sealer takes sealing performance to a higher level.
Super Radiator Sealer takes sealing performance to a higher level. Its unique combination of natural and synthetic components provides the ability to seal leaks up to 0.016” X 0.5”. What makes this possible is the size, strength, and durability afforded by fibrillated Kevlar® particles, the same materials in bullet proof vests. Super Sealer’s particles have been chosen to seal even large leaks without interfering with the flow through the radiator and heater core tubes.

Cooling System Antifreeze Treatment
Designed to help improve the protection of neglected antifreeze/coolant or extend the benefits of new antifreeze/ coolant. Patented grafted polymer technology helps protect nearly every major component of the cooling system, in just one treatment.
- Shake well to ensure uniform distribution of active ingredients.
- With engine off and cool, add entire contents to overflow tank or radiator.
- Replace radiator cap and run engine to mix thoroughly.
Patented grafted co-polymer technology helps guard against water pump failure with a super slick layer of heat-activated protection. When used as directed the treatment can help extend water pump life by reducing seal face friction and cavitation-erosion-corrosion damage to the water pump housing and impeller.

Stops Leaks
Fast dispersing pellets seek and seal most leaks in hose connections, radiators, heater core and gaskets. Corrosion inhibitors fight rust and scale.
DO NOT USE IN A DIRTY OR PARTIALLY CLOGGED RADIATOR.
If cleaning is needed, use Prestone® Super Flush. Not for use in pressurized overflow systems.
- With engine off and cold, remove radiator cap. Ensure there is enough room to add product.
- For cross-flow radiators, pour entire contents into radiator. For down-flow radiators, add all the liquid and enough pellets to fill top tank to bottom of filler neck. DO NOT PACK PELLETS INTO RADIATOR.
- Add 50 - 70% solution of Prestone® antifreeze in water to top off system. Replace radiator cap.
- Idle engine for 15 minutes with heater “ON” then drive 5-10 miles to disperse pellets.
- Check engine for leakage. If leak hasn’t stopped and you have a down-flow radiator, shut off engine and allow it to cool. Remove radiator cap, add remainder of pellets to radiator as in step 2, and top off system as in step 3.
- Repeat idle/drive sequence as in step 4. If leak hasn’t stopped after use of one bottle, mechanical repair may be necessary. Pour in a bottle every time the antifreeze/coolant is changed and the system has been flushed. Helps prevent against future leaks.
CAUTION: Do not remove radiator cap while cooling system is hot. After using product, wash exposed skin thoroughly with soap and water.
This product has fast dispersing pellets to seal small to medium leaks and also boosts corrosion protection for cooling system metals.
