You are unlikely to just take the old plastic flange off and swap it out with this one. Chances are that you'll have to drill out the holes like I had to as the original holes don't let you screw it in and seat it properly. Also as you can see the O ring supplied with this is larger (wall thickness of the rubber) than the OEM original (the pic has the supplied on the left). I ordered an OEM one instead to use on my N52 engine. ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United Arab Emirates 16 November 2025* Very good option to stop the keak ### ⭐⭐⭐⭐⭐ Great car part *by on Reviewed in Canada 3 December 2024* Great item worked well for my engine highly recommended 👍 ## Frequently Bought Together - VASTAUTO Aluminum Water Hose Fitting Upgrade Fit for BMW 1 3 5 6 7 Z4 (Engine N52 N53 N54 and N51 3.0-litre),Replaces# 11537541992 11537544638 Engine Coolant Hose Flange - VASTAUTO Engine Upper Radiator Coolant Water Hose Pipe Compatible with BMW E82 E88 E92 E91 E90 Z4 128i 323i 325i 328i 330i Replace 17127531579 - Jaronx for BMW Water Coolant Hose Pipe Thermostat to Front of Engine 11 53 7 545 890,Engine Coolant Hose for BMW 1 Series E87/E88/E82,3 Series E90/E91/E92/E93,5 Series E60,X1 E84,Z4 E85/E86 --- ## 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.tn/products/554862353-aluminum-water-hose-fitting-upgrade-for-bmw-1-3-5](https://www.desertcart.tn/products/554862353-aluminum-water-hose-fitting-upgrade-for-bmw-1-3-5) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-15*
