Coolant Hoses

Coolant hoses are the veins of your BMW cooling system. Often overlooked, these parts require a simple visual inspection for cracking, splitting, bulging or signs of wear. If there are signs of potential problems, the BMW hoses should be replaced preventatively with the correct part number for your BMW, either with one of our BMW OEM-style rubber or high-performance, long-lasting silicone replacement hoses or complete hose kits. Use our SEARCH BY MODEL feature to filter these items for your BMW.
