• Q: How to Replace an A/C Hose in the HVAC System on 2001 GMC Jimmy?

  A: The replacement of the evaporator tube starts with battery removal and the recovery of refrigerant gases from the system. After finishing the installation process you must use the halogen leak detector (J 39400-A) to check for leakage in the fittings. Disassemble the installation by removing the evaporator tube retaining screw before you detach the evaporator tube from the accumulator and the evaporator. Unscrew the o-ring seal and detach both the lower Radiator Hose and the evaporator tube from the condenser as well as its o-ring seal. You must begin installation by using a 525-viscosity refrigerant oil-coated new o-ring seal before connecting the evaporator tube to the condenser with 28 n.m (21 lb ft) of torque. Attach the lower Radiator Hose, which uses another new o-ring sealed with 525 viscosity refrigerant oil before securing the evaporator tube to the evaporator (torque to 28 N.m / 21 lb ft). The evaporator tube clip should be mounted on the accumulator while securing the retaining screw at 1.9 n.m (17 lb in). Rephrase the steps by replacing the battery then empty the system before recharging it.
