  • Why should I add Water Pump Lube With Anti-Rust to my radiator?

    Because antifreeze alone is not enough to keep the 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 all brands of antifreeze including conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) coolant.

    One 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.

  • “IMHO every single car should have this installed in their cooling system. I mean it. I work at a car dealership, and in hot and cold extreme weather, we see cooling system issues all the time, and often it's the water pump that goes bad. That's an expensive part to replace, but like a mechanic co-worker said, simple problems can usually be prevented by simple solutions. He told me to buy this Bar's Leaks water pump lube, and I did for my mid-80s SVO Mustang. Cheap insurance, worth a few bucks. Good SIMPLE thing to aid in prevention.”

  • “I had good luck with rust inhibitor and water pump lube. It does not lube the water pump per se but it makes the o-ring seal stay flexible. (When the o-ring is not flexible it will let coolant get by and that will ruin the water pump bearings.) I am 75 and I never had to replace a water pump. I have a 1953 tractor that leaked coolant then I added water pump lube and it stopped leaking. I have a 2010 Chevy Cobalt that leaked at 60,000 miles I added two bottles and now have 145,000 miles on the car without a leak.”
