Designed for easy DIY use, this pack of four offers an affordable, reliable fix for common engine coolant leaks—just remember to flush antifreeze before application. ## Description Suddenly noticing your temperature gauge spring towards the high end is not the best way to start your day. School, work, errands — your daily routine should not be compromised due to head gasket problems. When you experience this problem, you probably think about the time and money that will be spent in search of a block seal solution. But there’s good news: a cracked head sealant doesn’t have to be expensive or time-consuming. Our Bar’s Leaks Head Gasket Repair is scientifically formulated to permanently seal coolant leaks that are the cause of most overheating problems. It’s easy to apply, and it’s available at only a fraction of the cost of getting the same block seal fix from a mechanic. How does the need for cracked head sealant come up in the first place? Usually by overheating, which can be caused by a blown head gasket, cracked head or a leaking block. Bar’s Leaks Head Gasket Repair eliminates this problem — . This product contains a blend of aramid and refractory fibers, which provide the strength of a bulletproof vest and the heat resistance of fireproof clothing. As these particles penetrate a crack or the blown head gasket area, they lock together and bond, forming a hard, permanent ceramic-type seal. At Bar’s Leaks, we employ a team of top-flight chemical engineers who specialize in solutions such as these. Each product, our cracked head sealant included, is custom-designed to be effective, affordable and easy to install. You don’t need any special automotive expertise — you just need to be able to pop and lift your hood. The rest is about as simple as any car maintenance can be. Forget that repair bill. Simply use this product and get back on the road and back to your daily routine in no time — with several hundred extra dollars in your pocket. Review: dont buy - useless product, and some residue stays on the reservoir Review: It does what it says - I given three of this product to mechanics with details as how to use it. The product sealed the leak into the engines crank case. The only problem with it is that it is a long and time consuming treatment process (up to 24hrs.). But considering the money saving it is worth the trial. May I remind you that water in the crank case is a very corrosive substance and when you gets blown gasket, you should fix that right away. ## Features - Stops block leaks - Seals cracked cylinder heads and blocks - Repairs blown head gaskets - Dual Action 2 Part Formula — LIQUID CERAMIC: Liquid penetrates large and small leaks to form a seal actually harder than the original head gasket — REINFORCED FIBERS: Fiber additives lock together with liquid to increase strength and promote a permanent seal - Head Gasket Sealant is NOT COMPATIBLE with antifreeze and must only be added to the cooling system after ALL ANTIFREEZE has been flushed and removed. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BYS6SV2 | | Best Sellers Rank | #29,926 in Automotive ( See Top 100 in Automotive ) #123 in Automotive Fillers, Adhesives & Sealants | | Brand | Bar's Leaks | | Customer Reviews | 3.9 3.9 out of 5 stars (24) | | Date First Available | 22 May 2019 | | Item Weight | 635 g | | Item model number | 1100-4PK | | Manufacturer | Bar's Leaks | | Manufacturer Part Number | 1100-4PK | | Model | 1100-4PK | | Package Dimensions | 21.11 x 19 x 10.79 cm; 635.03 g | ## Images ![Bar's Leaks Block Seal Head Gasket Sealant (Pack of 4),1100-4PK - Image 1](https://m.media-amazon.com/images/I/61S2FMKwngL.jpg) ![Bar's Leaks Block Seal Head Gasket Sealant (Pack of 4),1100-4PK - Image 2](https://m.media-amazon.com/images/I/61Ao8rIpHYL.jpg) ![Bar's Leaks Block Seal Head Gasket Sealant (Pack of 4),1100-4PK - Image 3](https://m.media-amazon.com/images/I/51SFF6fN3zL.jpg) ## Customer Reviews ### ⭐ dont buy *by A***N on 25 August 2026* useless product, and some residue stays on the reservoir ### ⭐⭐⭐⭐ It does what it says *by K***I on 25 March 2014* I given three of this product to mechanics with details as how to use it.
