  • Water pump and thermostat Every version Replace every 100,000 miles

    Ask the seller: Ask when the water pump was last replaced.

    If it was skipped: BMW Tuning says to replace it about every 100,000 miles, that some fail as early as 60,000, often with little warning, and to replace the thermostat at the same time.
