Failure Symptoms

Inconsistent or insufficient cabin cooling is a primary indicator of a failing expansion valve. If the problem persists, the AC system may cease to function altogether, leading to discomfort for the operator and potential distraction. This can impact driver performance and safety during long hauls.

Installation Tip

Ensure the AC system is properly evacuated and recharged by a certified technician to prevent refrigerant loss and contamination. Avoid bending or damaging the sensing bulb of the expansion valve during installation.

Service Note

It is recommended to replace the receiver-drier and flush the AC system when replacing the expansion valve to ensure system cleanliness.
