    I have a1998 ford f150 with 432,000km the left cyl bank started leaking trucks a farm truck not worth replacing or rebuilding engine. So i gave this a try. Prior to this product coolant would bubble and drip from head gasket the coolant temp would fluctuate and it would need coolant added every 2nd gas tank. Now temp is stable drip is gone and coolant level is stable. I dont know how long this truck will last but its fixed for now. Im sure it wont fix all issues but cured this truck. I added coolant directly to top heater hose not in the rad or overflow tank.

    Yes, I recommend this product.

    I tried K&G fiberblock part#75224 about a week ago in my Ford F-150 3.5 Ltr in hopes of buying some time before doing the head gasket, instead this product has plugged the radiator thermostat and even a portion of the water jacket in the engine . So instead of buying time I have bought a world of hurt !

    No, I do not recommend this product.

    Q: Is this product comparable to "Blue Devil Pour-N-Go Head Gasket sealer?

    • A: The FiberLock product is designed for the same use but there are two main differences. Firstly, the FiberLock is a Pour and Go product, no need to flush out the cooling system before use, just pour and go! Secondly, the main ingredient in the FiberLock is the Military grade fibers. These fibers permanently seal the leak and will last a lifetime. Just be sure to follow the instructions exactly as they are written on the bottle, do not over pour or add the product in too fast. Directions on the label are very clear.
