How To Use K&W FiberLock From CRC To Fix A Coolant Leak




What do you think about this video?

John Norvaisas: Can i use fiber lock in my 1997 BMW 740il? 

Lei Yan: Don't use it. Its just crap. Clogged my cooling system. My car get overheated. Can't even drive it.

Viet Hoang-Tran: Something doesn't make sense about this video explaining fiberlock. This fiberlock gets mixed into the coolant and flows through the system until it goes into a "leak". The video states that "air in the cooling system passes over the patch" but why would there be air in the cooling system? Aren't cooling system bled of air? How does the fiberlock know to "seal" a leak versus "seal" a thermostat or radiator or coolant jacket?

Edwin Potts: JUNK...now to fight to get my money back and take my radiator out to unclog it

Ahmed Marouf: I used K&W Fiberlock for my 2006 Kia Spectra, and the result is unbelievable. It stopped the air bubbling COMPELETLY within two days. I highly recommend this product. Thank you K&W to make me safe hundreds of dollars in replacing the gasket.

arabiantxn: Read all the reviews read all the review. unfortunately i am not happy , 

arabiantxn: Good luck this product didn't work for me. Part of the coolant was drained , this product was directly added along with coolant directly to radiator. K&W FiberLock didn't work for me cost (autozone ) $35.99 2003 infiniti G35 v6 3.5

Jeremy Crane: Blocked all my coolant ports so my car runs hot in record time... matter of fact about 1 mile down the road is all it took to blow off ny top coolant hose, if you decide to use this product be sure to flush your system out soon after you do it and change oil IMMEDIATELY!!! I wish I had just changed my headgasket in the first place, oh yeah I almost forgot... my heater core is blocked beyond belief so when the winter comes ill be pissed beyond belief... my car is a 1989 ltd crown vic with the 5.0

marco33717: can I use this on my turbo car??

Snc: Is it better to add it when the car is cold and then warm it up after it's poured in? Or get the car to full operating temperate and then add it?

fcrespomt82: How use in a cadillac deville with problems head gasket

Kelvin Smith: Would this work for my northstar v8 engine?

Sergio Sierra: I just got your product today, Do this work for an Chrysler 300c 5.7 hemi v8???

Tom Taylor: My coolant is not leaking after adding fiberlock, but the car is overheating. It had a new thermostat and water pump before adding the fiberlock. Any ideas on what to do next?

Azhr M: This K&w will clog you radiator, resivoier and every small coolant passage then you're looking at more things to fix. I tried K&w few times never worked but added to the problem. I had better luck with blue devil. If you have northstar engine or mercedes or any engine has open cylinder wall nothing will fix it other then making new bolts (time-sert) and new head gasket. But if you have steal block and straight no double cylinder then the blue divl will most likely fix it.

david thomas: check you cooling fans could be a fan relay

CRCAuto: Hi Kelvin - the short answer is yes, however it depends on the type of problems you're experiencing. We recommend you call our Tech Line at 1-800-521-3168 to discuss your specific issues and we'll steer you in the right direction. Thanks!

lampson1986: I used FiberLock to stop a coolant leak. So far after running the car for 15 minutes, it looked good at idle, until I revved the engine, then the leak game back. I'm going to wait a little while to see if it helps, and try and rev the car again. So far not impressed, however its doing a better job than Bar's stop leak.

CRCAuto: Sorry it took a while to respond. If you haven't tried the product already, here's the best way to install: The vehicle should be cold to start. Remove radiator cap, then start the vehicle. With engine idling, shake FiberLock vigorously and pour 1/3 of the bottle very slowly into your cooling system. If the leak persists for more than a day, slowly add a second dose per the treatment ratio for your vehicle. Call 1-800-521-3168 if you have specific questions. Thanks!

Chef de NYC: Thanks! I'm more info ultrasound type of work. I learn most of the stuff myself online. Just only recently start looking for a school to make things "official". Hehe
