Let’s Talk About Chemical Additive Myths

Stop us if you’ve heard this one before: a chemical additive (stop leak) doesn’t work, it clogs up your cooling system, and it actually makes your problem worse. It’s a waste of money.

Sound familiar?

Every day, we talk to customers who are reluctant to use another chemical fix because they’ve been burned in the past. They have every reason to doubt: many chemical fix products are more marketing than engineering. Too often, they don’t work as promised.

Testimonial: Bar’s Leaks Head Gasket Repair Saves a $2,000 Hard Repair

Paul F. from Pacifica, CA writes:

I have a comment about the instructions. Most mechanics say they don’t like it (probably because it does not make them a cent) because it tends to plug the small passageways in the radiator and cause overheating and engine failure.
