{"product_id":"coolant-expansion-tank-16","title":"Coolant Expansion Tank","description":"The Rein expansion tank is a direct replacement coolant reservoir for your BMW, engineered to be identical to the original BMW part #17111712835. This component plays a critical role in managing coolant expansion and contraction within the cooling system.\n\nIt is common for the plastic coolant expansion tank to degrade over time due to constant thermal cycling and system pressure. This degradation can lead to brittleness, cracking, and subsequent coolant leaks, potentially causing engine overheating and roadside stranding. Replacing this tank is often recommended as a preventative measure when servicing other cooling system components.\n\nManufactured by Rein Automotive (CRP), this expansion tank meets all of BMW's original design, fitment, and performance requirements and is TUV approved. Rein Automotive is an original supplier to BMW and offers OE-quality parts that are virtually identical to OEM parts but at a more competitive price point. This part comes with a two-year warranty.\n\nThis expansion tank is compatible with the following BMW models: 3 Series E30 (84-91) 318i\/318is, 3 Series E36 (92-99) 318i\/318is\/318ti (M42\/M44 engines), 5 Series E34 (89-95) 525i (M50 engine), and Z Series E36\/7 \/ E36\/8 Z3 (96-02) Z3 1.9. Please note that this product does not include the expansion tank cap or level sensor, which should be purchased separately if needed.","brand":"BMW Genuine Parts","offers":[{"title":"Default Title","offer_id":52872365343032,"sku":"17111712835","price":17.61,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/coolant-expansion-tank-16","provider":"MOTORMIA","version":"1.0","type":"link"}
