I would highly recommend this product. 2 of 2 people found the following review helpful K-Seal, Amazon Verified Purchase This review is from: K-Seal ST5516 HD Multi Purpose One Step Permanent Coolant Leak Repair (Automotive) Fixed the leak within 3 minutes of application. Great stuff.I did not know exactly why I was leaking radiator fluid out of the back of the engine, but what ever it was this stuff sealed it within 3 minutes of application. Very happy. Stopped head gasket leak while on vacation in our PowerStroke Diesel truck, This review is from: K-Seal ST5516 HD Multi Purpose One Step Permanent Coolant Leak Repair (Automotive) While far away from home passing thru a tiny Utah town, our one ton diesel truck blew a head gasket...the dealer quoted a $4800 repair and a several day repair assessment. A short, panicked trip to the CarQuest store and an employee offered FREE small sample of K-Seal, which we accepted in disbelief and great anticipation, was our only hope, both financially and within our closing time frame, of returning back home quickly, with our vehicle, which had just expired it's dealership warrantee. We followed the directions and silently watched the muffler. Within a few minutes the white vapor smoke dwindled and after a few passes up and down the short, main street thru town, there was NO SMOKE and the muffler was no longer blowing moisture. In disbelief we continued driving back and forth thru the town (passing each time, the car dealership which had quoted us the repair expense). We stayed over night at one of their motels, just in case, however NO SMOKE and NO MOISTURE are being... Read more |

| 13 of 13 people found the following review helpful Fixed my heater core leak, This review is from: Bar's Leaks 1186 Liquid Aluminum Stop Leak - 16.9 oz. (Automotive) This is probably the best stop leak out there. I had noxious coolant steam coming in the cab of my truck. This means a leak in the heater core - very expensive fix, around $800 as the whole dash has to come out. Fixed it right away. NOTE - negative reviews and damage are most likely caused by misuse. If you do not regularly flush your cooling system, you will have problems. If you already have lots of gunk, this will pile on it and cause problems. 1) Get your system flushed first!, 2) Run the engine for at least 45 min(they say 20) and not just at idle, drive it. You can buy a kit to flush it yourself for $20 + $10 for anti-freeze. Make sure to leave the heat on HOT as some cars have a valve that bypasses the heater core until you call for heat. 9 of 9 people found the following review helpful Works Great!, Amazon Verified Purchase This review is from: Bar's Leaks 1186 Liquid Aluminum Stop Leak - 16.9 oz. (Automotive) Had a 2 different leaks in 2 different cars and it fixed both.1998 Volvo S70 - Fixed a leak in the heater-core; no longer smell antifreeze when the heat is on. 2006 Ford Explorer - Fixed a Larger leak in the radiator, and its been going with no antifreeze drips for 3-4 Months now. $500 Save! Anyways, I did read that someone fouled up their Radiator with this stuff. THE TRICK is in the dosage. 1 bottle per 4 gallon cooling system. Ford Explorer - 4 Gallon Cooling system = One Entire Bottle Volvo S70 - 2 Gallon Cooling System = 1/2 Bottle (It would gum up too if I added the entire thing probably) 1 of 4 people found the following review helpful  Don't Use This!!, By This review is from: Bar's Leaks 1186 Liquid Aluminum Stop Leak - 16.9 oz. (Automotive) I have a 2003 Honda Civic EX 1.7L. My car was running hot occasionally as well as low on coolant. I would top it off about every two weeks just to keep up with it. Every once in a while I would smell coolant so I knew I had a leak somewhere. At the rate of about 8oz every two weeks, I knew it had to be a small pin hole somewhere.I bought the liquid aluminum, read the instructions and followed them to the letter. It is a 4 cylinder car so I only used half a bottle, when the car was cool and while I was topping it off. I let it run 10 to 20 minutes after putting it in. At about the usual two week point, the car started running hot and was still losing coolant. The stop leak did not work. Only now I have the hose to my overflow tank popped off. I changed the thermostat and clamped down the hose. A little while longer the car is running hot and I see the same hose at another point has popped off. I flushed the entire system and clamped all points of the hose. I notice my overflow... Read more |
