Steel Seal Head Gasket Repair: Effective Solution for Blown Gaskets Steel Seal is a simple pour-in solution designed to fix blown head gaskets. It's compatible with all types of antifreeze and any vehicle with a water cooling system, making it a versatile repair solution for cars, bikes, vans, pickups, 4x4s, tractors, lorries, and boats. Compatible with Blue Antifreeze Steel Seal is fully compatible with blue antifreeze and can be added directly without draining the system. It can also be used with other types of antifreeze (such as red, pink, or OAT-based), but these may require additional steps—such as flushing and refilling with water Step by Step Instructions Step 1: Add to Radiator Ensure the engine is cold. Remove the radiator cap and add Steel Seal directly into the radiator. Refit the cap securely. Step 2: Circulate Turn the heater and fan to maximum. Start the engine and let it idle for 30 minutes. Step 3: Cool & Top Up Switch off and allow the engine to cool completely. Top up with antifreeze and water as required. Step 4: Drive as Normal Leave the product in the cooling system and operate the vehicle as normal. Lifetime Repair Repairs all types of side leaks in the engine. Classic symptoms: loss of cooling water, white smoke on the exhaust, oil in the cooling water, water in the oil, exhaust gas/pressure in the cooling system Review: Every time I've used it it's worked. - This stuff actually works really good. I will say follow the instructions carefully and it does say only works with blue antifreeze. When I use it I spend a bit of time flushing the system before pouring it in and I've not had any problems with radiator/heater getting blocked. So far used it in renault clio, SCv8 range rover, VW golf, Mitsubishi 3000. It worked on them all. The range rover was the biggest challenge as it was bad, emptying the coolant in about 30min of driving. Seems to last as a permanent fix golf and Mitsubishi have been running for a good few years and still good. Range rover ran 2 years before succumbing to other issues but gasket was still good. I was dubious about using it on forced induction engines due to higher pressures but it works no problem. Dont know how well it would work on a diesel engine but for the price of it it's worth a try. Review: Miracle product!!!! - I used this in my Audi A4 B6 1.8T 190 Quattro after it had developed a slight blow in the head gasket. After a week of white smoky start-ups I decided to try this before opting to shell out the thousands of pounds to replace the head gasket and to my amazement it has solved the problem!!!!! The car was perfect again and I sold it 3 weeks later for 50% more than what I paid for it in April 2020! 👍 No way that would of happened if I had not use this miracle product! ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful if swallowed. - May cause damage to organs through prolonged or repeated exposure. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Steel Seal | | Brand | Steel Seal | | Package Dimensions | 20.3 x 10.2 x 4.6 cm; 498.95 g | | Item model number | SS | | Manufacturer part number | SS | | Item Weight | 499 g | ## Images ![Steel Seal Blown Cylinder Head Gasket Fix Repair Sealer (Lifetime Guarantee) Award Winning - Image 1](https://m.media-amazon.com/images/I/61-DfdcNwmL.jpg) ## Questions & Answers **Q: Can you use on Diesel engines** A: Yes **Q: Got a leak at the back of thge engine (in garage now), will this work for all leaks?
