Well my time had come last winter Winter of 2024 and I was deciding whether to put new engine in it though I did not have the money and I called a repair shop in town called engine and transmission exchange and told him I dilemma. Well to my surprise The gentleman behind a counter felt my problem and told me try this he had a guy who delivered parts who had a old Chevy van that had the same head gasket issue. He gave it a shot because one of his mechanics told me to try it what's the worst that could happen. By God it worked that man has been driving that same vehicle for 5 years now so I gave it a shot. It's a year later I've had no head gasket issues whatsoever no overheating no loss of fluids since that time I put it in. Heck of a lot cheaper than the engine. A $23 bill is a heck of a lot cheaper than a 5 to $6,000 engine replacement. Review: Brought back life to 170k engine - Added this to our Pacifica with the dreaded head gasket issue on the pentastar. There was a slight leak on cylinder 6 causing coolant to fill the cylinder over night. Ran this through one cycle and came out next morning to a smooth running engine no check engine light and no puff of coolant vapor on startup. I had nothing to lose as with the car having 170k miles in it didn't feel like a 5000 repair was worth it. If this didn't work it would have went to the junkyard anyhow. I ran this with the cap off and no heat on as I did not have any issues with a heater core leak left cap off during cooldown over night to allow the pressure to possibly vent out of the expansion tank rather than pushing the sealant out. Time will tell how long it lasts but just gained myself a new fishing vehicle! As I said this was a very slight leak that wasn't noticeable really only at startup so your results may vary. ## Features - FIX IT FAST: Our advanced formula with 33% more sealing power than regular K-Seal, ensures a long-lasting, seal for challenging leaks.

It says to idle for 20 minutes** A: The system should be sealed as the product circulates though it for the 20 minutes. **Q: Does it use Sodium Silicate?** A: Nowhere on the bottle does it say sodium silicate. **Q: I have a 1999 ford ranger. running fine now but it is getting older. can i use this as a preventative? or do i need to wait for a problem to show up?** A: The way K seal works is by seeking out leaks in a pressurized system. I feel you or best bet would be to wait until you know your leaking coolant. I use this in a truck about 7 months ago and I still have no problems with the truck. Work very well **Q: can i make a 100 make a 100 mile trip 10 minuets after i put the k-seal in...** A: Yes! It does it's magic within 10 minutes. Just don't drive it too hard for about 20 minutes. Drive smooth. Highway driving or a good road with a consistent speed is best. After 20 minutes, you are all good! ## Customer Reviews ### ⭐⭐⭐⭐⭐ It actually works very well *by S***N on January 2, 2026* I have a 2012 Toyota Prius type v they're generation known to have head gasket issues over time.

Not just steam but coolant as well. Used K Seal and it did not work. So pulled heads sent to machine shop that checked them and said no faults found. Heads milled, inspected cylinders, nothing found. In fact old cylinder head gaskets and intake gaskets were okay. Re-assembly did not touch the exhaust. Just as bad. I again used K Seal. Forget the 3-5 minute idle, did not work. So allowed it to cold soak overnight. Next day ran it on the road with it blowing steam all the way. Let it cold soak overnight. Next day leak was gone. Went for drive and no smoke. Mind you this was just day one, but given the severity of the leak, this looks promising. Still not sure why it worked on the second can and not the first. I lost a lot of coolant when I pulled the heads, but it is possible enough residue of the first can of K Seal remained. My current thinking is that the problem may be a crack in the intake manifold and not the block. This is because the engine did not blow coolant before I changed the intake manifold gaskets a few weeks prior just as routine maintenance. The manifold EGR passage was totally clogged with carbon which I removed. It is possible this carbon may have sealed the crack in the manifold. Chevy manifolds have massive exhaust and coolant passages that run parallel to each other and a defective EGR system could generate excessive heat that cracks the manifold internally. This would allow coolant to get into the exhaust. ## Frequently Bought Together - K-Seal ST3501 Pour and Go Head Gasket Sealer, 16oz, Permanent Repair for Blown Head Gaskets, Cracked Heads and Blocks - K-Seal ST5501 Multi-Purpose One Step Permanent Coolant Leak Repair, 8oz, Pour and Go, Mixes with All Antifreeze, No Flushing Required - K-Seal ST5516 Heavy-Duty Multi-Purpose One Step Permanent Coolant Leak Repair, 16 oz, Pour and Go, Mixes with All Antifreeze, No Flushing Required --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/82132425-k-seal-st3501-pour-and-go-head-gasket-sealer-16](https://www.desertcart.kg/products/82132425-k-seal-st3501-pour-and-go-head-gasket-sealer-16) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-31*
