Couldn't be easier to install. Very affordable. The guy at AutoZone told me this is the company that invented stop leaks, so I chose this brand. Worked immediately, product lives up to its word. Very impressive to find a product like this in a sea of stuff that doesn't work. I'd recommend it. - Jack R. - Brooklyn, N.Y.
- Can Bar’s Leaks be installed in existing antifreeze?
This product is specifically designed to be directly added to the cooling system without having to flush out the antifreeze.
- Will Bar’s Leaks work in the new extended life antifreeze?
Yes, Bar’s Leaks works with all types of coolant including yellow, orange, pink, red, blue and green silicate –based and non-silicate based (OAT/HOAT) antifreeze and/or water.
- How does Bar’s Leaks work?
Bar’s Leaks will seal external, internal and coolant to oil leaks. Once installed, the Bar’s Leaks particles shrink up to 15 percent. The tiny particles flow to the point of the leak. They then collect at the outside of the seepage and build inward.
- How long does it take for the Bar’s Leaks to work?
We recommend you drive/idle vehicle for 15 minutes. In most cases the leak will be sealed with in this amount of time. If the leak is not sealed, a second application maybe required.
- Will Bar’s Leaks plug my heater core?
No, the tiny particles will pass through a 24-gauge mesh screen which is the spec for the BIG 3 car/truck manufacturers. They say that any product installed in the cooling system must pass through this screen. Bar’s Leaks is the only stop leak to pass this test and to be approved by the vehicle manufacturers. Note: If using Bar’s Leaks to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core.
- What are the dosage recommendations?
One tube treats systems up to 3 gallons.

“Used this at least 3 times in the past, and keep some in my glovebox in my Jeep for when I go wheeling (coolant and radiator damage is something I'm good at LOL). Always works, super easy to use even trailside. Everyone should have this in their car for emergencies. Easy on the ol' wallet too.”
