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 first sign of a failing evaporator is a noticeable decrease in cooling efficiency. If left unaddressed, the system may stop producing cold air altogether, leading to an uncomfortable operating environment. Continued operation with a compromised evaporator can potentially lead to compressor damage due to moisture ingress.

Installation Tip

Ensure the AC system is properly evacuated before removing the old evaporator to prevent refrigerant loss and environmental contamination. Avoid overtightening mounting bolts, which can distort the evaporator core and cause leaks.

Service Note

Inspect the cabin air filter and blower motor for proper operation when replacing the evaporator.
