Why should I add Anti-Rust and Water Pump Lubricant to my radiator?

Because antifreeze alone is not enough to keep water pump seal & thermostat lubricated, and inhibit the formation of rust and scale within the radiator.

Is it compatible with extended life anti-freeze?

Yes, it is compatible with both conventional green (silicate-based) and extended life red/orange or yellow (OAT) antifreeze.

How much do I install?

1 bottle treats a standard passenger vehicle/light truck. Over the road and heavy duty equipment – install one bottle for every 16 quarts of coolant.

How often do I install?

Once a year, every 15,000 miles or anytime cooling system is serviced.
