How to repair a cracked engine block or head gasket with K&W FIBERLOCK


[intro music] Stop leaks, start driving! This car’s engine has overheated, repeatedly. Overheating can sometimes be caused by the cracked engine block, leaks from the cooling system, or coolant leaking past the head gaskets. A crack in the engine block could be an expensive repair, but with K&W FiberLock® Head Gasket and Block Repair you can be back on the road in 20 minutes. K&W FiberLock® is the most advanced product for repairing cracked head gaskets and engine blocks. When there is a crack or hole in your block or cooling system, the pressure in the system causes heat to build up around the crack. Fiberlock® seeks out the hot spots and seals them permanently with 3 levels of protection. Military strength fibers create an interlocking web over the breach. Nanoparticles fill-in and create a solid bond to the metal. Cool-X™ Conditioner keeps your engine running cooler long after the repair is made and FiberLock® is compatible with all types of antifreeze. Now let me show you how you can do this yourself in just a few minutes. No tools are needed. Before starting, read all the directions and have your owner’s manual ready to look-up system details. You will also need to know the capacity of your point system. This can be found in your owner’s manual. Let’s get started! First, make sure the engine is cool enough to safely remove the radiator cap. Next, always wear eye protection and gloves when doing any type of maintenance or repair on your vehicle. Now, locate and unscrew the radiator cap. Be careful not to add FiberLock® to the oil. Shake the bottle well for 30 seconds and start your car. This is necessary to circulate FiberLock® in your cooling system. Very slowly, add the required amount of FiberLock®. Replace the radiator cap. Turn the heater on to high. Let your car in idle for 15 minutes and you’re done. After the engine cools down, it’s always a good idea to check the fluid level of the radiator and add some coolant and if it’s low. If the leak persists for more than a week, you can repeat the treatment with FiberLock®. But, if you’re losing more than a half-gallon of coolant in 30 minutes no cooling system additive will be able to fix your leak and you’ll need a professional repair. K&W products have been stopping vehicle leaks for nearly 80 years. We offer a wide range of products for common leaks. See our other problem solvers at K&W.com [music] Stop leaks, start driving.

  1. I have a 2001 f-150, i noticed a slight coolant leak between one of the heads & the block & i noticed some oil in the coolant reservoir , will this product work for this?

  2. what if i dont have a radiator cap? can i just pull the top hose off, pour k&w fiberlock down the hose, connect the hose back up, then start the vehicle?

  3. I have a cracked head gasket no mixer in the cooling system but mixer in the oil what kind should I use

  4. I SEALED MY FORD V-6 '96…..DON'T LISTEN TO THIS BULLSHIT THAT YOU DON'T HAVE TO REMOVE YOUR ANTI-FREEZE….YOU NEED TO DRIVE YOUR CAR OUT ON THE HIGHWAY 500 PLUS MILES… MY CAR WAS PUTTING MOISTURE IN THE EXHAUST. IT MAY HAVE TAKEN MORE THAN THAT, EVEN TO GET IT POUNDED IN. IT WAS NOT TREMENDOUS LEAK LIKE MASSIVE VAPOUR YOU CAN SEE IN THE REAR-VIEW MIRROR. BUT A MODERATE AMOUNT.

  5. THE LAST TIME I ADDED A BIT MORE, IT DID BLOCK MY HEATER FROM WORKING. I HAVEN'T DRAINED THE SOLUTION, AND RE-ANTI-FREEZED YET, BUT I THINK IT WILL HAVE TO HAVE SOME WATER FORCED THROUGH THE HEATER CORE, TO OPEN IT BACK UP.

  6. I got my 2004 Saturn ion to start after replacing nasty, burnt plugs, sealing with blue devil head gasket sealer adding water and oil. The blue smoke died alot after driving home. Sat in driveway for about 2 hours before I attempted to start again. Car cranks over like b4 but won't start. What's my next step?

  7. Don't believe this mickey mouse garbage. If your engine block is cracked. Your engine is fucked. Head gasket no. But if you don't know what your doing it will cost you. Hopefully your headers are on top of the engine. That will be an easy repair.

  8. Ok people if you dont trust this product use bars brand they have some good products as well but k&w worked for my 04 v6 mustang without having to drain and flush radiator and engine

  9. DO NOT USE THIS CRAP.

    This crap gonna clog your cooling system and cause overheating eventually.

    That will cost you more than $1000 since you have to replace not only radiator but also waterpump, thermostat, heatercore.

    Some people may try flushing first, but you won’t be able to take this shit out completely.

  10.
