What is the purpose and how to replace a plugged fixed orifice tube in an air conditioning system on Ford Crown Victoria?

Restriction of the flow of liquid refrigerant into the evaporator core is done by the fixed orifice tube assembly. The evaporator temperature is controlled by a pressure-operated electric switch. In cases where high pressure is extremely high and the low pressure is nearly a vacuum, then the fixed orifice tube is blocked and it needs to be replaced. To take it out, disconnect the liquid line connection, lubricate the O-rings, use a special tool to extract the tube, and cap an open line.

Ford Crown Victoria A/C Orifice Tube

The Ford A/C Orifice Tube of Crown Victoria vehicles functions as a restriction point to control refrigerant liquid movement between the low and high parts of the A/C system. The dual function difference between the expansion valve and orifice tube emerges from their transfer method because the expansion valve operates with moving parts but the A/C Orifice Tube functions as a stationary metering component which controls compressor activity. Due to accumulated debris the Ford A/C Orifice Tube gradually deteriorates causing problems with inconsistent cooling or evaporator smoothing in Ford Crown Victoria vehicles. The proper functioning of the A/C system demands regular maintenance because neglected orifice tubes produce severe performance deterioration. A Y-junction structure connects the condenser and evaporator system where the Crown Victoria A/C Orifice Tube works. Experts agree that clearing the tube requires its complete removal for A/C maintenance operations. The A/C system requires new tubes if the existing ones show damage or extreme dirt because it ensures proper system functionality.

We provide a wide range of Ford Crown Victoria A/C Orifice Tube at the best prices possible. If you need Ford Crown Victoria A/C Orifice Tube, you can shop with confidence on our website.
