Before we begin, set the refrigerant oil so there isn't too much pressure on the compressor and remember to install new O-ring seals as soon as the A/C line is removed to stop leaks. Untape or unplug the fittings and condenser ports, first and then grease new rubber O-rings with clean oil before pressing them into the fittings, always selecting the right O-rings and recommended type of oil. Bring the front A/C liquid line (5) into the engine compartment, support the vehicle in a raised position and join it to the middle section (4) by fastening the bolt to 8 Nm (70 in. lbs.). Secure the line on the left frame rail with two nuts, hand-tighten them to 4 Nm (35 in. lbs.) and when needed, install the underbody A/C lines and heat shield. Next, remove the air chamber by lowering the car on its secure digging points, then press down the A/C liquid and discharge lines onto the condenser and ensure they remain fixed by tightening each 6 Nm (53 in. lbs.) Once more, link the negative
Battery Cable, expel the refrigerant, fine-tune the oil in the system, charge it and put the air cleaner housing in place. For step two, take off more tape or plugs, put in O-ring seals, lube the area, install section 3, attach it to section 2 and complete everything with a bolt tightened to 8 Nm (70 in. lbs.). Fix the middle section to the front section; add two nuts to the left frame rail, but only tighten them to 4 Nm (35 in. lbs.). If you have rear A/C, put in your underbody lines and heat shield, lower the car, put back your negative battery cable, evacuate the refrigerant system, lower the refrigerant oil to the correct level, charge the system and place in the air cleaner housing. First, remove any tape or plugs; then, lubricate, insert the O-ring seals, put on the rear valves of the liquid (3) and suction (2) lines, hoist the vehicle, align and connect the rear lines to the middle sections (11 & 4), finish by tightening the bolt to 8 Nm (70 in. lbs.). When needed, fit the underbody A/C lines and shield, lower the car, tighten the rear section of the suction line to the center with a bolt at 8 Nm (70 in. lbs.), join the rear section of the liquid line to the
A/C Expansion Valve (1) with a bolt tightened to 6 Nm (53 in. lbs.) and secure both lines to dash panel with nuts at 4 Nm (35 in. lbs.). For diesel engines, put the wires in their harness and bracket onto the cleaner housing bracket and firmly install two retaining nuts. Now, join the negative battery cable, clear out the refrigerant, check the refrigerant oil, charge the system and put in the air cleaner housing.
