Good fix for less
I have a 2001 suburban with a small radiator leak. After using this product I was an immediate decline in how often I needed to top off the coolant. I think this is a good fix if you have a minor leak. It is easy to use and the directions are clear and easy to follow.

    Great to seal radiator leak
    I have had a slow radiator leak in my PT Cruiser for about 6 months now. I have had to replace the antifreeze/coolant a lot more often and had also taken it to a mechanic to see what they could find. They said it was a minor leak but would require I keep replacing the fluids or have them repair the crack in the radiator. I did not have the money for the repair at the time so I kept adding antifreeze/coolant until I used K Seal Permanent Coolant Leak Repair. I have now been driving my car for one week and have not seen the antifreeze/ coolant levels go down at all. I haven't had to add any more antifreeze/coolant to my radiator now for a week so I am certain that this product has sealed off the crack. I now don't have to pay the mechanic to repair my radiator and am certain that this product has stopped the leak area.

    Fixed water pump leak!
    My mom has had a small water pump leak for a few months now so I decided to try this out on her car. All we did was shake the bottle so everything was mixed well, pour it in and run the car for a few minutes. No more leaks! Worked like magic.

    Good effective Product
    I was somewhat skeptical, but this product performed decently. My car had been slowly leaking coolant for a bit, and I was refilling the coolant like every so often. I received this K-Seal Coolant repair for free through the Spark Reviewer program. I added the k-seal to my car, let the car sit on for around 10-15 minutes then took it for a light drive afterwards. I checked on it again, and noticed there was a little sealant loss but nothing serious, way better than before, it worked decently well to me. I like it, and I would recommend this product to others.

    Keeping it sealed
    It works!! I added this pre- mixed k seal fluid to my radiator and it has completely sealed the leak. You have to shake the contents of the bottle well before using, add to the cooling system and run the engine until it reaches operating temperature so that the k seal fluid can flow freely around the cooling system and there you have it. No draining and it works with all types of coolant (antifreeze). It does state on the directions that if you add this directly to the radiator, to ensure there is enough coolant to cover the core. So very easy to use, even for me.

    K-Seal Perm Leak Repair
    I received this product free from Walmart Spark Review website to test on a vehicle at my home.. My Son's car had a leak in his radiator and to save him the cost of buying another radiator i told him about K-Seal Permanent Coolant Leak repair, he wasn't sure it would work as his car is older and well, after he read the info on the container, he decided to give it a try. K-Seal Coolant Leak Repair was poured into the radiator cap per the instructions on the container & we waited the appropriate amount of time to let it circulate thru the radiator to seal off the leak and see if it the radiator would hold anti-freeze again. After about 20 minutes, the dripping stopped and by looking at the area of the drip .. it was sealed.. You won my son's heart over to keep his car running.. Thanks to K-Seal .. its worth buying and using.. Won me over as i was skeptical.

    Saved my Radiator
    Saved me a lot of money after fixing a leak in the radiator of my GMC Canyon. It was hard for me to believe that a small container of K-Seal would plug up and stop a fast leak in my truck's radiator. I followed the really simple directions to install K-Seal You just shake the small container really well. Pour it in to the cooling system and start the engine! That's it! When the engine was warming up, a few drops of coolant was dripping from my radiatore. and then NOTHING!!! It stopped the leak completely. After a number of start ups and cool downs over two days, I can say that I have a permanent repair. I plan to tell everyone that I know about K-Seal Just unbelievable.

    So far so good!
    This product seems to have really stopped the small leak that I have been dealing with in my radiator. The day after I dumped it in, I put a large piece of cardboard on the ground under my radiator before going to bed and while I shopped in the grocery store. Neither time was there any fluid left on the cardboard. I am not going to miss lifting my hood to add anti-freeze. That was a pain in my side all winter. Had I known about this easy fix, I never woukd have let this go the way I did. I am happy that it's extending the life of my radiator, regardless if hiw long it may last because ir's one less expense I have to put into my aging car. I'd like to give a big thanks to K Seal!

    Works well
    This products worked as intended for me, it came with simple instructions that were easy to follow. It did not have a very chemical strong odor and was an off clear color so it was easy to clean up. It worked well for repairing the leak in my coolant system and I did not have to drain it as it mixes well with coolant or even water. You only need either half the bottle or the full bottle so its well worth the price as compared to expensive auto repairs. Overall I really liked this product and have no complaints
