Compatible with all vehicle types, it stops leaks within minutes of engine warming and continues to protect your cooling system, trusted by professionals and backed by over 12,000 positive reviews. ## Description POUR & GO, K-Seal’s advanced formula uses ceramic microfibres together with copper powder of varying size to ensure a fast and permanent seal holes up to 0.025in and cracks up to 0.01in wide by 0.5in long.The special chemical formulation can flow into cracks so fine that they cannot even be seen with the naked eye to form a super- strength seal. The crack or hole is actually filled from top to bottom with the K-Seal formula resulting in a complete ‘weld’ and permanent repair. The copper in the K-Seal formulation not only contributes to the strength of the repair but it also helps to conduct heat across the crack or hole. This eliminates hot spots that would normally form with a non-metallic repair.K-Seal can be left in the cooling system and will continue to repair leaks as they happen. You won’t even notice that there was a problem. Review: Good product, worked like a charm - I had observed oil leak signs in the coolant, Probably faulty oil cooler gasket or Engine head gasket. I poured this liquid to the radiator and drove my Thar crde for almost 30minutes. Next day had gone for 400kms drive as well. No further oil leakage. Coolant looks clean now. Its been almost 3 weeks now. Oil mixing with coolant has stopped perfectly. Review: Coolant leak fix - Works best for coolant leakage. I personally checked my car coolant levels for 1 week and are still the same no lekage. ## Features - Permanent Seal for, Holes and Cracks in Radiator - Head Gasket Repair,Block/Head Sealer,also for water pump casing heater core hard plastic,freeze plug,and Aluiminium - No draining/No Flushing, simply pore into coolant tank - Add K-Seal to coolant tank when engine is cold,leak will stop in 1-3 minutes after engine reaches operating temparature - Scientifically tested, Trusted by professional,MADE IN USA ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001QT9KO6 | | Best Sellers Rank | #8,592 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #9 in Fillers, Adhesives & Sealants | | Brand | K-Seal | | Brand Name | K-Seal | | Colour | Orange | | Compatible Material | Ceramic | | Country of Publication | USA | | Customer Reviews | 4.2 out of 5 stars 12,759 Reviews | | Global Trade Identification Number | 05060002968017 | | Importer Contact Information | SUPER TYRE TEC-No.35, 24&25, MJR Arcade, Rajaram MohanRoy Road, S R Nagar, Bangalore-560027. | | Included Components | A specially developed blend of chemical ingredients including | | Item Dimensions | 8.9 x 3.8 x 11.4 Centimeters | | Item Form | Liquid, Powder | | Item Type Name | Radiator Sealant Liquid | | Item Weight | 0.26 Kilograms | | Item dimensions L x W x H | 8.9 x 3.8 x 11.4 Centimeters | | Manufacturer | K-SEAL INTERNATIONAL LIMITED, K-SEAL INTERNATIONAL LIMITED-G B Unit 1, Plumpton Green Studios, Lewes BN73DQ.WWW.KSEAL.COM | | Manufacturer Contact Information | K-SEAL INTERNATIONAL LIMITED-G B Unit 1, Plumpton Green Studios, Lewes BN73DQ.WWW.KSEAL.COM | | Manufacturer Part Number | ST5501 | | Material | Plastic | | Material Type | Plastic | | Model | ST5501 | | Number of Items | 1 | | Packer Contact Information | SUPER TYRE TEC-No.35, 24&25, MJR Arcade, Rajaram MohanRoy Road, S R Nagar, Bangalore-560027. | | Style | Radiator | | Style Name | Radiator | | UPC | 367157659506 812646010004 | | Unit Count | 1 Count | | Warranty Description | NO WARRANTY | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** K-Seal - **Item Weight:** 0.26 Kilograms - **Item dimensions L x W x H:** 8.9 x 3.8 x 11.4 Centimeters - **Material:** Plastic - **Style:** Radiator ## Images ![K-Seal Plastic Permanent COOLANT Leak Repair Liquid 236Ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses, 1 Can - Image 1](https://m.media-amazon.com/images/I/71fLFvkh6wL.jpg) ![K-Seal Plastic Permanent COOLANT Leak Repair Liquid 236Ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses, 1 Can - Image 2](https://m.media-amazon.com/images/I/71lPrD2uF-L.jpg) ![K-Seal Plastic Permanent COOLANT Leak Repair Liquid 236Ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses, 1 Can - Image 3](https://m.media-amazon.com/images/I/81m2ndis4SL.jpg) ![K-Seal Plastic Permanent COOLANT Leak Repair Liquid 236Ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses, 1 Can - Image 4](https://m.media-amazon.com/images/I/81W878iqjGL.jpg) ![K-Seal Plastic Permanent COOLANT Leak Repair Liquid 236Ml - Stop Radiator Leak, Head Gasket Repair,Block/Head Sealer-No Draining/No Flushing,for All Cars, Light Trucks, Heavy Trucks & Buses, 1 Can - Image 5](https://m.media-amazon.com/images/I/71fGXotSj7L.jpg) ## Questions & Answers **Q: will this work for leakey gaskets?** A: It is designed to work on leaky gaskets. If you have a small leak this product might be an easy and cheap fix. It did not work for me. Perhaps my leak was too large. It is hard to tell. **Q: Does it discolor the antifreeze? Thanks** A: Unfortunately I can't say. I have a GM vehicle that uses the orangish color engine coolant and it and this product are so close in color it's hard to say if it would discolor the usual green-colored coolant found in non-GM vehicles. The other challenge is that I can only look at the coolant through an overflow reservoir and it's so dark when I look inside (I have to use an LED flashlight to see it adequately) that it would be hard to tell if there was any discoloration. **Q: Can you use this in a 2013 escape?** A: You can use it anywhere. It's kept my 1998 Chevy Lumina going over 2 years with almost 178,000 miles on it! **Q: can you mix this with barstop if you all ready put that in the radiator?** A: I did mix this with Irontite All Weather Seal. Did the K-seal first. Irontite a week later. Just to be sure. Since they both said it can remain in the system. Two weeks, still good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product, worked like a charm *by V***N on 7 November 2024* I had observed oil leak signs in the coolant, Probably faulty oil cooler gasket or Engine head gasket.
