We received the following testimonial about our Bar’s Leaks Head Gasket Fix from Curtis Ding, who used it on his 2002 BMW 530i with 127K miles:

I would normally not contact a company to comment about a product, but much to my surprise, I am pleased to say that I have had a successful outcome after using the Bar’s Leaks Head Gasket Fix.

I have a 2002 BMW 530i with 127K miles, which I have just completed a head overhaul, and head gasket replacement after suffering a bad top end leak between the cooling system and combustion chambers. Despite performing a proper and complete repair, immediately after completing the repair, my car was still blowing steam, although not huge amounts, but my cooling system was also pressurizing to the point of multiple connection points developing small coolant leaks as well.

Despite all the time and money spent on the repair in the first place, it became apparent to me that perhaps I have a block or head crack that was not previously detected. Perhaps the machine shop never actually pressure tested the head, despite telling me they did. Regardless, I sill had a problem.

Despite being tremendously skeptical, I did some research and decided to try the Bar’s Leaks Head Gasket Fix, despite the steep price compared to other products. However, as this product contains sodium silicate, which is also known as “Liquid Glass”, I do know from a scientific standpoint that this is probably the only chemical that would have a chance of fixing a combustion leak, and as this product could be added to the antifreeze without the necessity to flush and run with only water, it was quite convenient and simple to use.

It has now been about 4 days, and about 250 miles or so. As of this morning, I have no steam that I can detect, even when cold. I do not have ANY coolant loss, and the cooling system over-pressurizing seems to be gone, although I have not yet performed an actual pressure test. I am absolutely astonished as this product has exceeded my expectations. I also still have FULL heat, so apparently my heater core is also working fine, and as I’ve been monitoring the car’s temperature with an external scanner for the past few days, the car’s temperature has also been functioning in the correct range as well. Bravo to Bar’s Leaks. This product saved me from having to replace my car.

Thanks Curtis!
