      1995 Pink Cadillac Back In Action

      I have a 1995 Pink Cadillac Seville that was billowing smoke and idling and running rough. I was directed to get another engine in August last year. Just yesterday I ran into a mechanic that mentioned KW Fiber Lock at Auto Zone for $35.00. I bought the last bottle on the shelf and took it to the mechanic. After the fifteen minute application of fiber lock, I drove the car for 30 minutes and by the time I returned home it was no longer smoking. Today it is running smoother, idling smoothly and it has not overheated as it used to do. Great product with immediate results. Wish someone would have told me about this last summer!!!!!

      Pros: Affordable, Simple Instructions for use

      Cons: Not advertised to the public

      Stay away from K&W Fiberlock

      0 of 1 people found this helpful

      I had a small coolant leak and used this product as directed. It clogged up my heating system and I ended up paying $$$ to replace the heater core on my 2002 Jeep Grand Cherokee. Also they have not made good on their money back guarantee either. I will never use this product nor any other from this company.

      Pros: None

      Cons: Will clog your heating system

      Adding great life to and old classic

      I have a 1981 Pontiac Grand Prix 350 Diesel. I just bought a used engine from a wrecking yard and installed it in my car. I discovered the head gaskets blown and I couldn't keep coolant in the cooling system. I decided to not take the engine apart because I'm disabled and it would take me forever to fix this problem. The cost of having some body repair it for me was out of the question. I first used another brand of stop leak and head gasket repair and it never fixed the problem. I decided to buy your K&W Fiberlock 32 oz. After I used a radiator and cooling system flush. I flushed fresh water through the cooling system. Poured fiberlock in the cooling system and ran the engine about 1/2 hour with heater on high and no thermostat. This engine gets great fuel mileage, that's the main reason I still have this car, besides it's a classic. I believe this car will still run for years. I've had it on the freeway at 75 mph and this car just rolls gently down the road. On the road my wife and I got about 40 mpg. Thanks for allowing me to add life to a great car. No cons!! Great product.

      Pros: Worked as advertised with very little effort. At the first sign of a cooling system problem I would use this.

      Cons: I'm only sorry that I didn't find this product first.

      Do not waste your money!! Product is garbage.

      Bought this product expecting it to work wonders on my leaking head gasket. Absolutely did not work at all. In fact after following the manufaturers instructions exactly now my minivan does not even start. It started fine to run it as per the instructions. I turned it off to top up the antifreeze and when I tried to restart the van it does not even start now. Then tried to check the fluid level and all the antifreeze is no longer inside the radiator filled again and just keeps bubbling away. Then after calling customer service I was told 10-12 weeks for a refund. Do not waste your time or money on this product. Should have zero stars not even one.

      Pros: None

      Cons: This product does not work at all.
