Followed directions and now my head gasket doesn't leak but my radiator is totally clogged. Rad was new.** A: It’s a 32 ounce bottle. If you’re putting it in a car you should only use 10 ounces. I wonder if you didn’t use a whole bottle, perhaps? I added a whole bottle to my Kenworth and my problem was solved. I had a Radiator seam leak in a plastic/aluminum radiator **Q: is there a limit to size of leak?** A: I had a small leak on the head gasket it sealed it fine I believe it would seal a larger leak, be sure to take your thermostat out and flush the cooling system at least four times follow the directions on the bottle. **Q: how clean it** A: I wish to know that. I suggest all headache should go to the manufacturer because she did make function test except it does 'block the leaking'. I believe she does not know how to prevent the block of the coolant level sensor; how to prevent the trigger of high temperature warning from the temperature sensor of the engine...etc. **Q: My 01 Civic only took 1/2 of the mixture (1qt sealant + 3qt water), even after burping - it took no more. Is this OK?** A: run it ## Frequently Bought Together - K&W 401224 FiberLock Head Gasket & Block Repair - 32 Fl Oz - K&W 401232 Permanent Head Gasket & Block Repair with Nanotechnology - 32 Fl Oz - CRC K&W 401016 Block Seal Permanent Metallic™ Block & Radiator Seal - 16 Oz --- ## 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.sn/products/6911365-k-and-w-401224-fiberlock-head-gasket-and-block-repair](https://www.desertcart.sn/products/6911365-k-and-w-401224-fiberlock-head-gasket-and-block-repair) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-02*
