A-Premium AC Evaporator Core for Chevrolet GMC Cadillac Hummer — 2003–2014 Fit, OEM-Style Direct-Fit Replacement

A-Premium AC Evaporator Core is a direct-fit replacement evaporator designed to restore factory-style cooling performance in compatible Chevrolet, GMC, Cadillac and Hummer models.

When an evaporator core leaks, clogs, or fails, cabin cooling drops and the air conditioning system can struggle to reach comfortable temperatures. This A-Premium unit is engineered to match original equipment dimensions and mounting points so it installs without modification and helps return efficient heat transfer to the HVAC system. Built to meet OEM fit and quality expectations, it comes with a one-year unlimited-mileage guarantee for added confidence.

Which vehicles will this evaporator core fit?

This evaporator core fits a broad range of full-size trucks and SUVs from General Motors produced in the 2003–2014 era.
