- Cooling system service on 2007-2009 Honda CR-V models
Installation Notes
Compatible With 2007-2009 Honda CR-V, N/A. The fitment notes specify Japan-built vehicles and use of a Micro, 16 psi cap. Verify inlet and outlet orientation, core dimensions, and oil cooler configuration before installation. The cap is not included, so reuse or source the correct cap separately if required by the vehicle setup.
