Review: Works well, stopped a minor leak in 2002 vortec v6 - I've used this stuff twice in 20 years and both time it worked great. The first was in a 1998 grand cherokee that was driven across town with low coolant resulting in a blown head gasket or cracked cylinder head. The second a 2002 S10 v6 that ran great but consumed a half gallon of coolant every few days. In both cases I added the full bottle and drove the car. In the case of the S10 it took a couple days driving to work but it's been a month now and no leaks. Saved me a ton of work replacing the head gasket and/or cylinder head(s). Review: great product - No more minor leaks . Water pump no more noise. ## Features - manufacturer: Bar's Leaks - Item Trademark: BAR'S PRODUCTS - Item Weight: pounds, pounds, 1.30, 1.30 - Item Category: Sealant ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002PX91OG | | Best Sellers Rank | #50,503 in Automotive ( See Top 100 in Automotive ) #193 in Automotive Fillers, Adhesives & Sealants | | Brand | Bar's Leaks | | Brand Name | Bar's Leaks | | Compatible Material | Copper | | Customer Reviews | 4.3 out of 5 stars 1,369 Reviews | | Global Trade Identification Number | 00046087011096 | | Item Dimensions | 19.1 x 6.6 x 6.6 centimeters | | Item Form | Liquid | | Item Weight | 18 Ounces | | Item dimensions L x W x H | 19.1 x 6.6 x 6.6 centimeters | | Item weight | 18 Ounces | | Manufacturer | Bar's Leaks | | Material | Sodium Silicate | | Material Type | Sodium Silicate | | Model | 1109 | | Number of Items | 1 | | Part Number | 1109 | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Copper | | UPC | 046087011096 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Brand:** Bar's Leaks - **Item dimensions L x W x H:** 19.1 x 6.6 x 6.6 centimeters - **Item weight:** 18 Ounces - **Material:** Sodium Silicate - **Style:** Compact ## Images ![Bar's Leaks 1109 Block Seal Liquid Copper Intake and Radiato - Image 1](https://m.media-amazon.com/images/I/618jCtXmpHL.jpg) ## Questions & Answers **Q: Will this help to stop a block leak where the water pump connects to the cooling system?** A: No. This will only help with small leaks. As temp fix. **Q: Can it be used on 1968 327cid for leaking freeze plug?** A: Yes, Our formula permanently repairs larger leaks in radiators, intake manifolds and gaskets, heater cores, blocks, heads and freeze plugs. It contains an antifreeze-compatible sodium silicate liquid glass formula, so no draining of the cooling system is required. Not to mention, it will not harm the cooling system when used properly. The intake gasket seal you’ve been looking for is far more effective, easy to use, and less expensive than you’ve ever imagined. This is why Bar’s Leaks exists: to offer usable, low-cost intake gasket seal and other products to auto owners who have no special experience or expertise. We’ve been doing this for over 70 years, so we know a thing or two about chemical repairs. One bottle treats cooling systems from 12 quarts (3 gallons) to 24 quarts (6 gallons). Use 1/2 bottle for cooling systems from 8 quarts (2 gallon) to 11.9 quarts (2.99 gallons). For larger systems use one bottle for every 6 gallons of cooling system capacity. Small engines or other small systems use approximately 3 fluid ounces per gallon of fluid capacity. If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website. **Q: heater core leak fixed?** A: The label on the lower right does show Heater Core. So this could work since coolant is being pumped through the heater core to heat the cabin of a vehicle. **Q: Can this help with a 5.3l gm engine with the bad cylinder head castings? i'm saving for a replacement engine, just need this one to last a while** A: Thanks for your question, and for considering Bar's Leaks to help with your vehicle's needs. The product you are asking about - Bar's Leaks Block Seal Intake & Radiator Stop Leak is a great product for repairing larger leaks in radiators, intake manifolds & gaskets, heater cores, blocks, heads and freeze plugs. However, if your vehicle is showing signs of head gasket failure due to the bad castings you refer to, we would suggest one of our head gasket products, such as Head Gasket Fix (part number 1111), which is very successful in sealing leaks as long as your vehicle can run 20 minutes or longer without overheating or needing to add coolant. If your vehicle is unable to run for 20 minutes without overheating, but can run for at least 15 minutes, we recommend our strongest head gasket stop leak - Head Seal Blown Head Gasket Repair (part number HG-1). For best results, these products should be installed into a clean cooling system, following the installation instructions and proper dosage. If you are unsure how clean your cooling system is, or you haven't had it chemically flushed in the last three to four years, we recommend doing so before installing any stop leak products. If you have any other questions, or we can be of further assistance, please feel free to call our Tech Support team at 1-800-345-6572. We are here to assist you Monday through Friday, from 8 am to 5 pm, Eastern time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, stopped a minor leak in 2002 vortec v6 *by M***E on 1 March 2026* I've used this stuff twice in 20 years and both time it worked great.

Water pump no more noise. ### ⭐⭐⭐⭐⭐ Thank you Bar’s Leak Sealant!! Something that actually works! *by G***N on 11 January 2026* OMG thank you for this wonderful product!! I used it in my old skid steer which was leaking a lot and overheating. Replacing the radiator does not seem to be an option- it’s above my ability and can’t find a mechanic to work on it. I had tried other radiator seal products with unsustainable results. As a last ditch effort I ordered this Bar’s copper block seal and it WORKS!!!! It has been several months and is still working, I am so very happy. The cost is a bit higher than the other products that did not work. For any future problems I won’t waste my money on cheaper products, this product is totally worth the extra few dollars. In the end it has literally saved me hundreds of dollars. ## Frequently Bought Together - Bar's Leaks 1109 Liquid Copper Block Seal, Intake and Radiator Stop Leak, 18 oz. | One Step, Safe for All Cooling Systems - PEAK 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems - ACDelco GM Original Equipment 10-108 (12378255) Cooling System Sealing Tabs - 4 g --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/259337869-bars-leaks-1109-block-seal-liquid-copper-intake-and-radiato](https://www.desertcart.tn/products/259337869-bars-leaks-1109-block-seal-liquid-copper-intake-and-radiato) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
