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 stepsβ€”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: Works - This stuff does work, how long for I don't know time will tell. Bought for my partners car as she was losing water somewhere, I put this in following the ideal procedure water out, engine flush, and adding back into the system, allowing to circulate round the engine. She's not lost any coolant upto now and its been over a week. Was very sceptical being a 40 quid bottle over what could be an expensive repair job but upto now it seems to have done what it needs to. Review: Almost worked - I wasn't sure if this would work as I was losing about 170ml of coolant a day and had water in the oil. I used this product as directed, took it for a few miles drive, let the engine cool and topped up with water to the fill line. I checked the coolant level after a few days and it was ever so slightly below the fill line. I can still smell exhaust fumes inside the cabin when idling which suggests that exhaust gases are seeping into the heater matrix so it hasn't fixed it fully but I think it may have bought me a little time. I'm scrapping the car soon anyway I just need it to survive another few months until I can afford another car. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful if swallowed. - May cause damage to organs through prolonged or repeated exposure (if swallowed). - Suspected of damaging fertility or the unborn child. - NOW WITH IMPROVED SHAPE - Even more durable effect: repairs all types of side leaks in the engine.

In case of high pressure in the cooling system: leave the cooling lid open during application. - PROTECTS COOLING SYSTEM: Unlike other "coolants", Steel Seal is 100% free of filling materials (fibres, granules, etc.). This prevents unwanted deposits and blockages in the cooling system. Due to its unique action (thermochemical bonding process), the repair remains permanent after successful application on the cylinder head gasket. - Preparation: The key is done: rinse the cooling system with clear water before application, if other Extended or Longlife mediums, additives or coolant have been used, or if the coolant has visible impurities. After applying Steel Seal, rinse the cooling system again with water and fill it with fresh coolant. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BU44H0 | | Best Sellers Rank | 16,688 in Automotive ( See Top 100 in Automotive ) 182 in Fillers, Adhesives & Sealants | | Brand | Steel Seal | | Customer Reviews | 4.1 out of 5 stars 528 Reviews | | Item Shape | Round | | Manufacturer | STEELSEAL | | Manufacturer Part Number | SSAT | | Material | Alloy Steel | | Model Number | 5052665000005 | | Number of items | 1 | | Shape | Round | ## Product Details - **Brand:** Steel Seal - **Manufacturer:** STEELSEAL - **Material:** Alloy Steel - **Number of items:** 1 - **Shape:** Round ## Images ![The Award Winning Steel Seal - Image 1](https://m.media-amazon.com/images/I/81QIk6jY9YL.jpg) ![The Award Winning Steel Seal - Image 2](https://m.media-amazon.com/images/I/51Rt58nhqwL.jpg) ![The Award Winning Steel Seal - Image 3](https://m.media-amazon.com/images/I/51K0gR5xDSL.jpg) ![The Award Winning Steel Seal - Image 4](https://m.media-amazon.com/images/I/41TILLdR4rL.jpg) ## Questions & Answers **Q: Can you use it on steering pump systems** A: Hi, No I would not suggest using this on steering Pump Systems Opie Oils **Q: I have a jeep cherokee 3.7 petrol engine with a blown cylinder head gasket.
