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 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

Did exactly what it said it would do and it worked. It sealed up a cracked head gasket and it is no longer leaking fluids. Car is no longer getting hot and it runs fine. Definitely worked and it was cheap. Do research before you use this as I've heard it CAN lock up certain engines, but for my Chevy 2002 Malibu it worked fine. Great purchase.

Worked for 2002 Chevy Malibu

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

[This review was collected as part of a promotion.] When I purchased my car I noticed the coolant had an oily sludge building up in the cooling system. I ran the car to operating temp after putting it in my coolant. Let it sit, after 2 more cycles I drained the coolant and replaced it with clean. The oil didn’t return

Had oil mixing with coolant

Rislone

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.
