{"product_id":"engine-coolant-reservoir-107","title":"Engine Coolant Reservoir","description":"The Genuine BMW Engine Coolant Reservoir, also known as an overflow bottle, plays a vital role in your vehicle's cooling system. As engine coolant heats up and expands, this reservoir provides a safe space for the excess volume. It then feeds coolant back into the system as it cools and contracts, maintaining optimal engine operating temperatures.\n\nIt is crucial for preventing issues like coolant leaks, cracking due to heat cycles, and fogging of the plastic which can obscure the coolant level. A failing reservoir can lead to reduced cooling system pressure and potential engine overheating.\n\nThis expansion tank is designed for BMW models with 4.4L V8 engines, including various years of the X5, X6, X7, 750i, 750i xDrive, M550i xDrive, M850i xDrive, and M850i xDrive Gran Coupe, spanning from 2016 to 2026. Ensure proper fitment by verifying your specific vehicle's year, model, and engine configuration.","brand":"Genuine","offers":[{"title":"Default Title","offer_id":52688545808696,"sku":"17138610658","price":128.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662663740.webp?v=1784890780","url":"https:\/\/store.motormia.co\/products\/engine-coolant-reservoir-107","provider":"MOTORMIA","version":"1.0","type":"link"}
