  • FIT 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 Mazda CX-9. Specifically engineered for the 3.5L and 3.7L V6 gas engine platforms. Verify your vehicle's engine displacement and original tank geometry before purchase.
  • This Coolant Expansion Tank integrates a calibrated pressure relief cap and precision-molded inlet/outlet ports. The hardware is constructed from heat-stabilized polymer to maintain a closed-loop sealing interface within the pressurized cooling system.
  • Designed to address structural integrity loss and erratic fluid level feedback caused by reservoir brittle-fracture. This hardware restores factory-specified pressure retention characteristics and maintains proper coolant geometry to prevent signal lag in the thermal monitoring loop.
  • Each unit undergoes burst-pressure validation and thermal cycles tested endurance (-40°C to 125°C). The tank walls are precision-engineered for consistent thickness to meet OE specifications for mechanical load balance and prevent expansion deformation under high-RPM heat loads.
  • Professional installation is required; ensure the cooling system is fully bled of air to maintain signal integrity. Includes pre-installed pressure cap for a direct-fit solution. Replaces OE# CY01-15-350A, CY0115350A, CY01-15-350H, CY01-15-350.
