Genuine Mercury Mariner A/C Orifice Tube

The A/C Orifice Tube on the Mercury Mariner controls the flow of refrigerant to cool the passenger compartment without overloading the A/C system. In contrast with the expansion valve, which has movable parts always adjusting flow due to temperature and pressure, the A/C Orifice Tube in most Mercury Mariner models is a fixed straw-like insert with a calibrated bore and fine mesh screen to trap shavings, moisture, and road grit. Thus, the A/C Orifice Tube forces the compressor to either pump harder or to temporarily shut off to maintain correct pressure. If this little piece gets clogged or wears out, you will experience limited cooling while idling versus cruising, musty smells in the cabin, erratic gauge readings, the A/C compressor cycling more than usual, and the evaporator frosting up to a block of ice, a pretty clear sign heat exchange has stopped. The updated Mercury Mariner hybrids feature an adjustable expansion valve rather than the conventional A/C Orifice Tube, which continues to be the preferred design for its low cost, lightweight, and simplicity of service. Depending on your setup, whether you need to keep or replace the A/C Orifice Tube on your Mercury Mariner, it is important for system efficiency, compressor protection, and consistent airflow on hot days.
