Instructions

1. With engine off and cool, remove radiator cap.
2. Shake bottle.  Pour contents into radiator.  For systems larger than 12 quarts capacity (check owner's manual), use a second bottle.  Be sure radiator is full.  Consult owners manual for coolant type and add 50-70% concentration of the recommended coolant, if needed.  Replace radiator cap.
3. Run engine at idle, with heater "on" for 10 minutes after reaching operating conditions.  Check for leakage.  If leak has not stopped after treatment, mechanical repair may be necessary.
4. With engine off and cool remove radiator cap and check fluid level.  Be sure radiator is full.  Add recommended coolant, if needed, to radiator and coolant reservoir.  Replace radiator cap.

Technology

This is a specially designed premium cooling system sealer with the added benefit of providing corrosion protection to cooling system metals.  The formula’s combination of natural and synthetic components provides the ability to seal leaks up to 0.016” X 0.5”.  What make this possible are the size, strength, and durability afforded by fibrillated Kevlar® particles, the same material used in bulletproof vests.  Super Radiator Stop Leak also contains corrosion inhibitors compatible with both conventional silicate, and extended-life organic acid coolants.
