    Q:
    How to Properly Handle an A/C Orifice Tube Replacement on Buick LeSabre? Posted by Customer
    A:
    The replacement process for the A/C Orifice Tube requires the usage of A/C Refrigerant Recovery, Recycling and Recharging (ACR4) System (J 39500-B) to extract refrigerant from the A/C system. First remove the A/C evaporator hose from retaining clips and cut it at the A/C Orifice Tube position to take out the A/C Orifice Tube from the line. Apply mineral base 525 viscosity refrigerant oil to the A/C Orifice Tube O-ring before its installation into the evaporator hose while properly orienting the short screen toward the evaporator and its arrow mark. You should assemble the A/C evaporator tube then tighten its O-ring joint connections to 27 N.m (20 lb ft). Proceed by reattaching the A/C evaporator hose to retaining clips then charge the system and complete the process with the Electronic Halogen Leak Detector (J 39400-A).

    Q:
    How to replace the A/C Orifice Tube in an A/C system on Buick LeSabre? Posted by Customer
    A:
    The first step in replacing the A/C Orifice Tube requires refrigerant recovery and disconnecting the a/c Evaporator hose from its retaining clips. The a/c Evaporator hose needs separation at its A/C Orifice Tube location before removing the A/C Orifice Tube from the hose line. The new A/C Orifice Tube installation demands mineral base 525 viscosity refrigerant oil lubrication for the new o-ring prior to its insertion into the Evaporator hose while you also must ensure that the short screen with arrow points toward the Evaporator. Fit the a/c Evaporator tube while tightening its o-ring joints to 27 n.m (20 lb ft), followed by installation of the a/c Evaporator hose in the retaining clips. Before completion the technician will do a system recharge while also using the halogen leak detector (J 39400-A) for component fitting leak testing.
