305-0400 A C Evaporator — Cat 4M40 314D

This is an A/C evaporator core, the component responsible for absorbing heat from the cabin air to provide cooling. It is manufactured to meet stringent OEM quality standards, ensuring efficient heat exchange and durability compared to worn or damaged units. Failure typically manifests as a lack of cold air from the vents, a musty odor, or visible signs of refrigerant leaks around the unit.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The primary symptom of a failing evaporator is a significant reduction in cooling performance, with air from the vents feeling warm or ambient. If left unaddressed, the system may lose refrigerant, leading to complete loss of cooling and potential damage to the compressor. Continued operation with a compromised evaporator can lead to increased strain on other A/C system components.

Installation Tip

Ensure the A/C system is properly evacuated before removing the old evaporator to prevent refrigerant release. Avoid over-tightening mounting bolts, which can distort the evaporator casing and lead to leaks.

Service Note

Inspect the cabin air filter and the A/C system's expansion valve or orifice tube when replacing the evaporator.
