• Q: How to replace the A/C Orifice Tube on 2001 Chevrolet Malibu?

  A: The replacement of the A/C Orifice Tube starts by recovering the refrigerant and then raising the vehicle. First remove the bolt securing the Evaporator hose assembly to the condenser then take out the assembly while capping or taping the open condenser line. The A/C Orifice Tube removal tool j 26549-e should be used to extract the tube while simultaneously discarding the o-ring. Secure the A/C Orifice Tube edge with needle nose pliers while keeping away from the filter screen then gently remove it by pulling cap the Evaporator tube with tape to prevent contamination. Examine the tube for all signs of damage particularly broken plastic frames and torn or obstructed filter screens or damaged brass a/c orifice tubes (1,2) then replace it when needed. When reinstalling a previously used tube you must replace its o-ring with a brand-new one that received a thin layer of mineral base 525 viscosity refrigerant oil coating. Both Evaporator and condenser lines get their end caps removed before users install the A/C Orifice Tube using the j 26549-e. The line fittings need cleanliness with a lint-free cloth and new o-ring seals go on the condenser tube with 525 viscosity refrigerant oil applied to the area. Secure the Evaporator hose assembly onto the condenser while fastening the bolt with 25 n.m torque (18 lb ft). The service process requires first lowering the vehicle before evacuating and recharging the a/c system. Conduct a leak test on the component fittings through the usage of the j 39400-a halogen leak detector.
