Frequently Asked Questions
Cooling System Water Pump Lube with Anti-Rust (p/n 1311)Download PDF
- 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.
- Can I use in my race car?
Yes, it is a must if running only water in the cooling system, especially racing applications.
- 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.
