Do Head Gasket Sealers Actually Work (FULL 2yr TEST with Engine Teardown)

Replacing a Head Gasket can be difficult and expensive. Sometimes your car is not worth fixing and this is where a head gasket sealer in a bottle comes in handy. Do these head gasket sealers actually work? How long do they last? How do they work? What does a bad head gasket look like? Do head gasket sealers clog radiators?

In this video I show you how to use a head gasket sealer to repair the head gasket and test it for 2yrs and 10,000 miles. I then tear down the engine and show you how the headgasket failed, how the sealer worked, and if the radiator got clogged up with sealer.

  1. So it was brought to my attention that my house phone number is on the oil analysis sheet. I am waiting for YouTube to blur it so in the meantime, please dont call it…

  2. I have used the bars leak head gasket fix but what I have done is every so often I add more gasket fix to keep it working my 91 Subaru legacy has been this way for almost 4 years now and still going just a thought

  3. what in the world, who did they plan on having install that head gasket at the garage, Hellen Keller? 60 hours at 100 an hour to replace a head gasket good god. I think Ray Charles could do it faster

  4. Hola, que tal vas después de echar el sellador? Llegaste a hacer prueba de co2, el liquido azul que se vuelve verde? Tu coche hacia presion y te llegaba a tirar refrigerante? Aceite en el refrigerante o viceversa? Muchas gracias de antemano

  5. People are always so quick to change or repair a bad head gasket. Gaskets dont just blow there is always an underlying cause that needs to be fixed first

  6. Amazing video! As everyone has said! Question though… what do you do if your car doesn't have a temp gauge.. to know when it's at opt temp.. astra cdtdi 1.3 full tank of water being used every 10 min drive. No leaks from underneath. No white in oil.. YET! Help a gal out.. the car isn't worth a new head gasket just until I find soemthong else…

  7. Hey everyone, I used the Bar's Leaks H1 Head Sealer on a 2003 Honda CRV with 145k miles my daughter let overheat, over a loose lower radiator hose clamp leak. After following the instructions, it worked for me and stopped the white smoke from exiting the tailpipe as well as loss of coolant. The only downside was the loss of cabin heat do to it clogging the heater core. I flushed the system but the overheating, loss of coolant and white smoke returned so I again introduced the Bar's Leaks and all symptoms once again stopped. I actually had to install an electric heater to help keep her warm. She was able to use the vehicle for an additional 3yrs before another unrelated mechanical, situation arose, and we made the decision to donate the vehicle.
