I've used it in many different vehicles as a stop leak and preventive measure over a 20 year span great product great value highly recommend

walmart.com

haven't had a leaking problem since my husband put it in a few months ago.

not leaking now must work

I had a small coolant leak. I'd see a drip or two after I'd drive my car. I used this stuff making sure to follow the instructions and it actually worked! No more drip! Couldn't believe it I've tried other stop leak stuff with other vehicles that I've owned and nothing has ever worked this is the first one!

It worked!!!

I replaced my water pump, and much to my dismay found another leak somewhere behind and below the pump. I was afraid that the head gasket might be leaking, and used Bar's liquid copper to try and abate the leak. I also removed the thermostat so that this product did not clog it up.
This stuff worked great! I have put many miles on the truck without incident....I would recommend using this product should you not want to invest in having head gaskets replaced.

Great stuff for small leak

Follow directions closely, It can gunk up radiator if you use too much.

I put it in my coolant reservoir like stated because my radiator isn't one that has a cap and it didn't go through the system just stayed in my reservoir

My leak may be in a hose or some other component that the leak seal doesn’t work on but after using a full bottle on my 2011 Nissan Juke the issue is not resolved.
