My Reivew

I liked this product. We tested it on 4 cylinder Nissan Altima that my neighbor have purchased. He was able to buy it for only $1,500 because the coolant was leaking and needed to be added every other day. After replacing water pump, thermostat, and all hoses, it was still leaking. I suggested that he should try Bar’s Leaks Head Gasket & Cooling Sealant before replacing anything else. Since this product got a lot of positive reviews, I wanted to see if it really works. We poured it into the radiator, ran the car for 15 min and the leak was gone. He has been driving for over 3 months now without adding more coolant. This product was pretty easy to use and I think it was worth the money.

Consumer Reviews

Being new to the market this product has very impressive reviews. Consumers gave this product 4.7 out of 5 stars. The buyers liked the product and were very happy with the results. It was easy to use and only took 15 min to repair the damage. The product didn’t get any negative reviews, which is unusual (probably just needs more time) but a few people noted that the fix was not permanent. Also, it is kind of on the higher end comparing to other sealers.

Consumer Quotes

“This is the best product on the market it has fixed a 1998 Northstar head gasket leak, it has fixed a 2001 Grand am 3400 head gasket leak.”

“I have a Chevy Monte Carlo 1997 that had a serious blown head gasket. This product stopped the leak in about 10 minutes and it has not returned. AMAZING! This product is expensive but it works great!”

“OMG, I had a major head gasket leak with fluid leaking into my oil, oil leaking into my radiator fluid, white smoke coming out of the exhaust. Once I put this sealer in it was like a brand new engine! It was really like magic in a bottle!”
