EV 940178C UAC A/C Evaporator Core

It absorbs heat from the air passing through the HVAC case so the system can deliver cold air to the cab. As an A/C evaporator core, it also helps remove moisture from the air for improved comfort and defogging. It’s one of the primary air conditioning and heating evaporators responsible for consistent cooling performance.

Match the EV-940178C evaporator part number to the tag or markings on the unit being replaced whenever possible. If the old part number isn’t readable, confirm fitment by vehicle year/make/model or by VIN-based lookup through your preferred parts reference. Verifying that it’s the right truck air conditioning evaporator helps avoid issues with HVAC case fit and line connections.

Internal restrictions or debris on the fins can reduce heat transfer and airflow, which raises vent temperatures even when pressures look close to normal. A leaking UAC evaporator core can also slowly lower refrigerant charge and cause intermittent cooling. When replacing an A/C evaporator core, it’s wise to inspect the expansion device and ensure the condensate drain is clear to prevent repeat problems.
