About this part

This thermal expansion valve controls refrigerant entering the front evaporator. Four Seasons says each valve is calibrated to the tonnage, superheat and maximum operating pressure of its system, since a wrong or poorly made valve can cause AC complaints. It is aluminum with precision machined ports. O-rings, gaskets and seals come with it. Four Seasons says it meets or exceeds OEM fit, form and function.

Fitment notes
