Ease Of Application

Instruction Clarity

Provides reliable heat during cold weather.

When I did this repair on my radiator, unfortunately there weren't any instructions on the package... I learned from mechanic that I didn't need to use ALL 5 TABLETS, but a Half of ONE would have been sufficient lol.  A $3 repair turned into a few hundred dollars to have the radiator flushed out.  STILL sealed up, though!

ONLY NEED ONE!

I admit it. I was skeptical. But I decided for the price I might as well try it. I followed the instructions exactly and after idling for 15 minutes, there was no longer a radiator leak! Unbelievable! My leak was in the reservoir so I could see it every day. I would also get constant reminders from my vehicle telling me to add coolant. That all stopped once I added this product. Almost 30 days have gone by and still no problem. Highly recommend.

IT WORKS!

I literally shook it up cranked my truck poured out in the radiator and within five minutes my leak was gone!

I have been using this product since the 1980's and it has always seemed to be my go-to in times of trouble. Bars-Leak has a proven track record!

Great product

I had a small antifreeze leak.   Couldn't see it or find it but could smell antifreeze in the car cabin but not the exhaust.  Put 2/3 of a bottle of this and it fixed the leak with no adverse impact on car radiator performance or car heat.

I had a radiator leak but no time to replace the radiator. The stop leak did a good job sealing the leak until I had time to replace the radiator.

Stopped the radiator leak

My fan isnt working so if my car doesnt benefit like its supposed to   It wasnt a fail trial

Could begood

Didn't work at all. Don't waste your time or money.

DIDN'T WORK! Don't waste your money!
