It is a critical plastic housing mounted directly to the engine block or cylinder head that serves as the primary junction for the cooling hoses. Manufactured from high-temperature reinforced polymer, it is designed to withstand the intense thermal cycles and vibrations characteristic of BMW’s high-torque N57 diesel engines.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eOn the N57 straight-six diesel platform, this flange is a notorious \"preventative maintenance\" item. Because it is made of plastic and bolted directly to the hot engine, the material eventually becomes brittle (crystallized) over time. The most common failure point is the \u003cb data-path-to-node=\"2\" data-index-in-node=\"273\"\u003einternal mounting ear\u003c\/b\u003e or the thin plastic \"neck\" where the radiator hose attaches. When it fails, it typically results in a rapid coolant leak that can lead to engine overheating. Since the N57 is an all-aluminum engine, maintaining a sealed cooling system is vital to preventing warped cylinder heads.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003e\u003cb data-path-to-node=\"3\" data-index-in-node=\"0\"\u003eVehicle Compatibility:\u003c\/b\u003e This flange is designed for the \u003cb data-path-to-node=\"3\" data-index-in-node=\"55\"\u003eN57 3.0L Straight-6 Diesel\u003c\/b\u003e engine:\u003c\/p\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003e3 Series (F30):\u003c\/b\u003e 2008–2019 (325d, 330d, 335d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003e5 Series (F10):\u003c\/b\u003e 2010–2020 (525d, 530d, 535d, M550d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003e7 Series (G11 \/ G12):\u003c\/b\u003e 2008–2020 (730d, 740d, 750d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,4,0\"\u003e\u003cb data-path-to-node=\"4,4,0\" data-index-in-node=\"0\"\u003eX3 (F25) \/ X4 (F26) \/ X5 (F15) \/ X6 (F16):\u003c\/b\u003e 2010–2018 (30d, 35d, 40d, M50d)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eEngine Application:\u003c\/b\u003e N57 \/ N57S \/ N57Z 3.0L Diesel\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eMaterial:\u003c\/b\u003e Reinforced Polyamide (PA66-GF30)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eConnection:\u003c\/b\u003e Quick-release hose fitting\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MYTY Auto Parts","offers":[{"title":"Default Title","offer_id":48200930066671,"sku":"11117803751","price":350.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0769\/7183\/5631\/files\/2015-F30-328d-Diesel-Coolant-Flange.png?v=1774568395","url":"https:\/\/myty.co.za\/products\/engine-block-coolant-fitting-flange-bmw-n47-n57-diesel-engines","provider":"MYTY Auto Parts","version":"1.0","type":"link"}
