ST5516 HD Multi Purpose One Step Permanent Coolant Leak Repair

There was a crack in head gasket of my car and coolant was leaking from there. Results in engine overheating. I added Kseal HD in in coolant and I had driven 5000 KM after that and crack is healed hence no overheating. Authorised service centre had asked to change the head gasket , that could have costed me around Rs. 75000. Local mechanic suggested to weld the crack. That too have costed around Rs. 20000. But Kseal costed me only Rs. 3500. And it really worked for me.

It s not sealing coolant pump mild leaks.. I can only seal radiator leaks, not in other places- saying by my own experience.. if coolant pump leaks, u better repair it instead of wasting on it..

It fixed the problem only for 2 months or 1000kms on drive,i use s300 2004 model

So I have a 2005 Chrysler Pacifica, with about 206,000 miles. For the last 2 years I've been fighting this leak through the intake manifold gasket, where I would have to put in about of quart of coolant every 3 days. I've been working on cars all my life so I know how hard it is to change a head gasket or even a intake manifold gasket. Throughout the two years I've been using J-B weld aluminum extreme heat which were only suppressed the leak for about 2 months at a time. After doing a little bit of research I came across this product. Started watching videos and reading testimonials. I was like what the heck let me try it. The leak would occur usually about three to five minutes after I start my car. I added a little bit more coolant, and started my car. I followed the instructions shaking the bottle for 30 seconds vigorously and proceeded to pour the whole bottle into the reservoir tank. My car was really low on coolant so when I added the k seal it went directly from the reservoir into the block. I added a little more coolant to top the reservoir tank off and and place the cap back on the reservoir. At this point my car had already been running for about 5 minutes and what do you know not a trace of coolant was leaking. Like I said before this been happening for 2 years so I know that the coolant should have been leaking by now. So I let the car run for 30 minutes. I turned on the heat full blast just so it wouldn't get clogged into the coils of the heater core. Usually about 30 minutes of running my car the coolant would have been pouring out of the gasket in between the intake manifold and the head. There was no leak at all. After close inspection the area was bone dry. I have never witnessed a product that can fit fix a gasket leak like this one. It literally save me about $1,500 in costly repairs, actually would have been less because I would have been fixing it myself ,but still save me about 5 to 8 hours of labor. So my review for this product is definitely 5 stars and it definitely worked in my situation. I will update this in about 30 days. See the video for yourself. UPDATE: As of today, (May 19th). the leak is still sealed. It's been about 45 days and the seal is still going strong!

My neighbour swears by it. Says it fixed the leak on his truck perfectly and that was a year ago and the fix is still holding up! He only used half the bottle too so he still has the other half left. We however did not have as much luck but that was our own fault! We had a small leak at first, if we had known about this product and used it then, I feel like it would have definingly solved our problem! But we unfortunately ran the truck to the point where all the anti-freeze leaked out because we had bad head gaskets and it over-heated the engine and then unfortunately this couldn't fix the major problem we created. I would definitely recommend this if you have a coolant leak, use it early it will definitely help!

I had an unsatisfactory result with one of my cars I earlier reviewed. However, I had a visible gakset leak between the plastic intake manifold and cylinder head in 2007 Town Car, and was about to remove it for servicing until I thought, let me give K-Seal another shot since I had a small quantity left. The result was magic! The leak is gone, and been running dry and clean for a month now.

Funciona y es fácil de usar

Works great. Stopped the leak immediately. Small package, big results. Would buy again.
