What Sets Us Apart: Complete Kit

The Problem: The OE expansion tank systems for BMWs can fail over time. When they do, coolant may leak, which increases the risk of overheating. Compounding matters, it’s easy to damage the thermostat on the oil cooler when removing the expansion tank.

Our Response: TechSmart’s Expansion Tank Service Kits come complete with everything you need to restore function to the vehicle's cooling system:

  • Expansion tank
  • Coolant-level sensor
  • Oil cooler thermostat
