A/C Tube

The first step when replacing the discharge hose requires refrigerant recovery. You must first remove the mounting bolt from the A/C Compressor toward the discharge hose and then detach the discharge hose from the same location on the A/C Compressor. Begin by removing the upper radiator baffle and proceed with taking off the discharge hose nut from the condenser before you can detach the discharge hose from the condenser. The discharge hose removal process begins with electrical connector removal from the a/c recirculation switch followed by hose removal from the vehicle. All discarded sealing washers should be replaced. The procedure for installation starts with attaching the discharge hose to the vehicle before connecting the electrical connector to the a/c recirculation switch. The discharge hose needs new sealing washers before attachment to the condenser followed by tightening the condenser hose nut to 16 n.m (12 lb ft). Follow by putting in the upper air baffle before you can mount the discharge hose onto the A/C Compressor with fresh sealing washers while securing it with the discharge hose mounting bolt that requires tightening to 16 n.m (12 lb ft). The final step includes evacuating and recharging the a/c system while conducting a leak inspection of the component fittings through the halogen leak detector (J 39400-A).

Recruiting refrigerant from the a/c system must happen before adjusting the compressor hose assembly. Detach the compressor hose assembly bolt accompanied by its washer which allows you to remove the compressor hose assembly from the compressor unit. The compressor hose assembly should be removed from the accumulator before discarding its o-ring seal. Detach the lower Radiator Hose before removing the compressor hose assembly from the condenser along with discarding the o-ring seal. Begin by putting a new o-ring with 525 viscosity refrigerant oil coating then secure the compressor hose assembly to the condenser by applying 28 n.m (21 lb ft) of torque. Reinstall the lower Radiator Hose but apply another new o-ring seal after coating it with 525 viscosity refrigerant oil before attaching the compressor hose assembly to the accumulator while tightening it to 48 n.m (35 lb ft). Fasten the compressor hose assembly to the compressor while installing sealing washers first and tighten the bolt to 33 n.m (24 lb ft). The process ends with evacuating and recharging the a/c system and conducting a leak test of fittings through the halogen leak detector (J 39400-A).

The first step to replace the compressor hose assembly is recovering the refrigerant from the a/c system. First remove the compressor hose assembly bolt together with its washer before separating the compressor hose assembly from the compressor along with its sealing washers. You should remove the compressor hose assembly from the accumulator before discarding its o-ring seal. Take off the lower Radiator Hose before you remove the compressor hose assembly from the condenser by discarding the o-ring seal. The installation process starts with putting a new o-ring seal onto which you should apply 525 viscosity refrigerant oil. The compressor hose assembly requires tightening to 28 n.m (21 lb ft) when installed to the condenser. After reinstalling the lower Radiator Hose users must place a new o-ring seal with 525 viscosity refrigerant oil on it. The compressor hose assembly then connects to the accumulator before finishing with a 48 n.m (35 lb ft) torque. Install sealing washers before you attach the compressor hose assembly to the compressor unit including the washer and bolt placement and tighten the bolt to 33 n.m (24 lb ft). The a/c system needs evacuating and recharging followed by a leak test on the fittings through the use of halogen leak detector (J 39400-A).

Reinstall the battery, evacuate and recharge the refrigerant system, and perform a leak test on the fittings using the Halogen Leak Detector (J 39400-A).

Install a new O-ring seal coated with 525 viscosity refrigerant oil.

Remove the compressor suction/discharge hose bolt and the washer, then detach the compressor suction/discharge hose from the compressor and remove the sealing washers.
