Also fits 1998-2001 Audi A4 1.8T with AEB / ATW / AWM engine code. Parcel Includes: 1 x Cooling Hose Flange + 2 x Oring as photo shows Material Type: Top Quality of Aluminum Review: Works for Me - Installed this in my European automobile with engine code AWM. Be extra careful to seat the hard plastic connector and clip from the cooling hose in this aluminum flange before pressurizing the system. There's one o-ring that this product doesn't supply, but it was in the best shape out of the three, seemed to be the least critical considering the mating surfaces and design of the connectors, and the original o-ring was able to be reused without issue. This product seems to have stopped the mysterious slow coolant leak I had been searching for. Good enough quality, definitely a fair price considering tooling costs and all that. Thank you for supplying enthusiasts like me and whoever reads this. Review: Worked and fit great!

Much better than the plastic ones! *by T***B on September 8, 2022* Fit great, worked great, much better than the plastic ones. ### ⭐⭐⭐⭐ Make sure to buy 3rd o-ring for metal connecting pipe!!! Rough machined inside edges *by S***? on January 30, 2023* Not a bad idea to eventually replace yours from plastic to aluminum. These are expensive here on Amazon and just resold from AliExpress at 5x the price. All the kits are missing the metal supply line o-ring gasket but include the engine head to metal flange and coolant temperature sensor. Replacement is tricky due to space issues but easily done if you remove and flip the coolant reservoir out of the way and come in from the catalytic converter side with each arm. Good luck. Will update long term for how it held up. --- ## 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.us/products/97522410-upgraded-cooling-hose-coolant-flange-connector-in-cast-aluminum-vw](https://www.desertcart.us/products/97522410-upgraded-cooling-hose-coolant-flange-connector-in-cast-aluminum-vw) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-24*
