Therefore, before installing the air duct, be sure to replace the O-rings on the refrigerant line when breaking it free and make sure the front face of the instrument panel is safe from damage. Mount the defroster and instrument panel ducts in the instrument panel and fit and secure them with the HVAC housing. Put screws through the ducts into the instrument panel, tighten to 2 Nm (17 in. lbs.), then fit the two covers over the instrument panel and install it. After opening the refrigerant line fittings and expansion valve and
Heater Core ports, remove any tape or plugs from them. Just like the old seals, make sure that you grease the new rubber O-ring seals with clean refrigerant oil and mount them on the A/C system's fittings using only compatible R-134a system O-rings and refrigerant oil. Put the tube ends in the right position with the
A/C Expansion Valve and then tighten the line nut so you don't injure the sealing rings in the ends. Push the A/C liquid line and the A/C suction line onto the A/C expansion valve and tighten the nut with a torque of 6 Nm (53 in. lbs.). Screw the heater hoses into the heater core and secure them with the clamps. Set the air cleaner housing into place, connect the
Battery Cable, top up the engine coolant, drain off the old refrigerant and replace it with the right amount.
