Installation Notes and Tips

Verify the hose routing against the vehicle’s existing cooling layout before installation. Confirm the cylinder head to auxiliary thermostat position on the vehicle and compare the hose length and connection points to the removed part. Inspect adjoining clamps, thermostat housing connections, and nearby cooling components for wear or residue before reassembly. For BMW 320i, 325i, 325is, and M3 cooling system service, matching the routing exactly is important for proper fitment.
