Bar's Leaks Block Seal, Intake and Radiator Stop Leak is rated 3.3 out of 5 by 4.
Rated 5 out of 5 by from Bar's Leak Block Seal works This sealed a crack in a head on a 2000 Expedition 5.4L that was mixing coolant and oil into oil pan and coolant overflow bottle. Also used on a 2003 F-150 4.6L that was losing coolant into exhaust. Both repairs were in July 2015 and are running perfect, F-150 just back from Laughlin. Thanks!

Rated 5 out of 5 by from Saved the day Had a Jeep with a leaking freeze plug. Plug was in the worst place to reach and was going to require some major effort to change. Decided to try this product and leak stopped in minutes. Great product for emergencies or when changing leaking part is not an immediate option. Still holding strong.

Rated 1 out of 5 by from Clogged my entire cooling system! This is my first bad review of a product in 32 years. Had a small leak in my truck. Was in a pinch because of the holiday season. Figure use this product and I can then fix the small leak later. One use and one week later my entire cooling system was clogged up. Spent an additional $817 to flush the truck out and replace the radiator. Please do not buy this product.
