to flush out the antifreeze as long as manufactures recommendations are followed. It also can be used in
water alone. NOTE: Cooling systems that are dirty or partially clogged should be flushed before usage.
Do I need to drain my cooling system after using Cooling System Repair?
No, this product is designed to be left in the cooling system to protect from future leaks and overheating.
Can I install Cooling System Repair in my overflow reservoir?
Yes, if direct access to the radiator cap is not available, install in overflow tank.
Will it work in the new extended life antifreeze?
Yes, Cooling System Repair is compatible with ALL types of 50-50 mix antifreeze including yellow, orange,
pink, red, blue and green silicate based & non-silicate based OAT / HOAT coolant and / or water.
Will this work in both domestic and import cars and trucks?

How long does it take to see results?
We recommend you drive/idle the vehicle for 15 minutes. In most cases the leak will be sealed instantly, but
others will require up to 20 minutes. If the leak is not sealed in 20 minutes, a second application may be
required or mechanical repair may be needed.

leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow
through the core and is only opened in the HOT position.
What are the dosage recommendations?
Use 1 (one) bottle for regular size cooling systems, this covers most 4, 6, 8 and 10 cylinder engines. For
small cooling systems under 1.5 gallons, use half of each side of bottle. For larger systems, use 1 (one)
bottle for every 4 gallons of cooling system capacity.
How does Xtreme Cool™ make the vehicle run cooler?
The Xtreme Cool™ additive in Cooling System Repair reduces the surface tension of coolant increasing the
wetting ability. This improves heat transfer reducing coolant temperature helping to prevent overheating and
leaks.
The bottle froze before I was able to use it, what can I do?
If the bottle did not break from freezing, just let the product thaw out, shake well, and use as normal.
