It exceeded my expectations. **Q: why it is temp fix? crack due to vibration? how long it can last?** A: It will usually last a year as long as the car does not overheat which can cause too much pressure on the patched area **Q: Does j-b weld 2120 really work on radiatots?** A: It does if you work fast with it. **Q: I have a leak on a small stem (i think is aluminum) at the seam that holds a small rubber hose that antifreeze runs though, the small stem gets hot.** A: My honest opinion is this isn't going to work for your issue.... I used this on my plastic radiator at the top in small crack. It worked for couple weeks and had to buy new radiator... don't waste your money ## Frequently Bought Together - J-B Weld 2120 Radiator Repair Kit - J-B Weld High Heat Epoxy Syringe, Dark Grey - J-B Weld 8297 HighHeat 500 Degree Epoxy Putty Stick - 2 oz. , Grey --- ## 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.hr/products/750685170-j-b-weld-2120-radiator-and-plastic-repair-kit](https://www.desertcart.hr/products/750685170-j-b-weld-2120-radiator-and-plastic-repair-kit) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-12*
