Water Flange Head (Arrowhead) (316i 318i M43) is an auto part designed for BMW 316i and 318i models with the M43 engine. Check compatibility before purchase

Water Flange Head (Arrowhead) (316i 318i M43) is a vital cooling system component for BMW vehicles equipped with the M43 engine, including 316i and 318i models. This part helps direct coolant flow between the engine block and the radiator hoses, maintaining proper engine temperature and preventing overheating. Buyers should verify compatibility by comparing the old flange’s design and mounting points to ensure it matches the arrowhead shape and part specifics.

The water flange head typically mounts on the engine’s cooling circuit interface, serving as a junction for coolant passage. When inspecting your vehicle, note the flange’s condition for cracks or leaks, which can cause coolant loss and overheating. Replacing a faulty flange restores secure coolant flow and prevents engine damage.

For accurate replacement, confirm that the part numbers or BMW references, if available, correspond to the 316i, 318i, or M43 engine applications. This listing, SKU BB-252093, is specifically for the arrowhead-style water flange head used in those models. If unsure about fitment or matching your existing part, consult the Sales Desk or submit a Request a Part for guidance.
