Designed for vehicles that can idle without overheating, it creates a heat-resistant, ultra-strong ceramic seal compatible with cast iron and aluminum engines. This product offers a cost-effective, easy-to-follow solution to extend engine life and avoid costly repairs. ## Description For most vehicles, this is the last chance before going to a junk yard or paying an expensive repair bill. This product contains a blend of aramid and refractory fibers giving the strength of a bullet proof vest and the heat resistance of fire-proof 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. Your vehicle is a good candidate for this product if it can idle for 20 minutes without overheating or having to add coolant. Works effectively on cast iron or aluminum blocks & heads. Detailed instructions on back booklet label take you through each step of using the product. Review: Leak into the Cylinder - Had a small leak into one of my cylinders causing a misfire, after using this the misfire was gone. I’m not sure how long it’ll last but it gives me time to figure out the real problem. The directions were perfect and following them to a T will make it easy. As opposed to finding the leak this was a cheap fix. It does say it’s permanent but we will see how long it lasts while I save money for a mechanic. Everybody told me it would gunk up the heater but by following the instructions my heat works fine and no longer bubbles on the passenger side when i turn. 5 stars for a quick fix Review: Good quality - For a small leak this worked well ## Features - Stops block leaks - Seals cracked cylinder heads and blocks - Repairs blown head gaskets - Dual Action 2 Part Formula β€” LIQUID CERAMIC: Liquid penetrates large and small leaks to form a seal actually harder than the original head gasket β€” 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. - Included components: Unit, Instruction Guide ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #19,417 in Automotive ( See Top 100 in Automotive ) #25 in Gasket Sealers #946 in Oils & Fluids | | Customer Reviews | 4.3 out of 5 stars 771 Reviews | ## Product Details - **Material:** Aramid and Refractory Fibers - **Brand:** Bar's Leaks - **Style:** Custom - **Item Weight:** 1.41 Pounds - **Item dimensions L x W x H:** 1.8 x 3.4 x 8.3 inches ## Images ![1100 Head Gasket Repair Sealant, 20 oz - Image 1](https://m.media-amazon.com/images/I/81b4K9EXCBL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How do I get it into my radiator that does not have a cap but only a reserve for the overflow** A: This is a minor, although messy problem. Simply disconnect the upper radiator hose to get access to the radiator fluids. You'll probably need a funnel and maybe a little duct tape. My neighbor used a gallon milk jug as the funnel and his hand to make sure the fluid got where it was supposed to be. Also, if you drain it at any time, just take off the lower radiator hose. **Q: should I remove the old coolant before using this product?** A: Read the directions **Q: this product can fix a crack in the engine block of a car?** A: Although it is impossible to guarantee that it will work in every situation, it does quite often seal up block leaks...... It's most always worth a try, before you resort to rebuilding an engine. Thank you eric **Q: Its actualy 2 question. Does this work with V8** A: In my case it wont work ## Customer Reviews ### ⭐⭐⭐⭐⭐ Leak into the Cylinder *by J***N on July 5, 2026* Had a small leak into one of my cylinders causing a misfire, after using this the misfire was gone.

This caused over pressure and would blow all the coolant out of the radiator in just a few minutes. Since I've taken off diesel heads before and found them to be cracked or a crack in the block, I didn't want to go that route as a first effort. I want to use the tractor before winter comes darn it. I ordered this from Amazon, and followed the directions to the letter. Since I didn't have a spark plug to remove (remember, it's a diesel), I opened the compression release for each cylinder until I found out which one was giving me trouble and left that one open during the first part of the process. Net, this stuff worked. While the tractor was running I held the end of the overflow hose in a jar of water and watched the bubbles come out. In a few minutes there were less bubbles, a few minutes more, even less. I ran the tractor for a little longer than the instructions and then drained and refilled it. There were a few bubbles at first, as compared to a blast of compressed exhaust gasses when I started, and those went away after driving the tractor around the lot a little. It's only been a few weeks since I did this, so I don't know how long the fix will last. However, I got a bottle of the other Bar's product Block Seal 1109 and put half a bottle in the radiator to take care of any residual problem. Haven't had to add water at all and there are no bubbles in the overflow bottle. If you can't fix it right by replacing the proper parts, get this stuff; it actually does what it says it will. ## Frequently Bought Together - Bar's Leaks 1100 Head Gasket Repair - 20 oz. - Bar's Leaks OS-1 Oil Seal Engine Oil Burning and Leak Repair, 16.9 oz. - Bar's Leaks HG-1 HEAD SEAL Blown Head Gasket Repair --- ## 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.co.za/products/6912311-1100-head-gasket-repair-sealant-20-oz](https://www.desertcart.co.za/products/6912311-1100-head-gasket-repair-sealant-20-oz) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-30*
