Condenser

A correct removal of the condenser HVAC starts with battery terminal cable uncoupling followed by a minimum 90-second wait period for Air Bag safety. Start by evacuating the refrigeration system of refrigerant before you remove three bolts on the radiator grille, low pitched horn assembly, high pitched horn assembly and hood lock assembly. You must take off the hood lock support sub-assembly by detaching its clip and unfastening the two bolts. Thoroughly isolate the No. 1 cooler refrigerant discharge hose by unthreading its bolt then unhook its O-ring followed by wrapping the hose ends in vinyl tape to stop moisture and foreign materials from getting inside. The liquid tube sub-assembly requires removal of its bolt and O-ring before sealing both ends with vinyl tape. Disassemble the condenser with receiver assembly by uninstalling its two bolts. To install the condenser with receiver assembly use 2 bolts that require 9.8 N.m torque (100 kgf.cm, 7 ft.lbf). The liquid tube sub-assembly installation begins by removing vinyl tape before applying compressor oil (ND-OIL 8 or equivalent) to a new O-ring and its installation followed by securing the liquid tube using a bolt that reaches 5.4 N.m (55 kgf.cm, 48 in.lbf) torque. The No. 1 cooler refrigerant discharge hose installation includes removing the vinyl tape followed by compressive oil application to a new O-ring while installing the O-ring before securing the hose with the bolt at 5.4 N.m (55 kgf.cm, 48 in.lbf) torque specification. First install the hood lock support sub-assembly by bolting it two times to 5.0 N.m (51 kgf.cm, 44 in.lbf) torque and clip in before adding the hood lock assembly using three bolts. Reinstall the high pitched horn assembly together with the low pitched horn assembly and radiator grille. First normalize the hood sub-assembly before repairing the negative battery cable then initialize all systems that need it after reconnecting the cable to the terminal. The technician conducts refrigerant charging while heating up the engine while inspecting for refrigerant escapes.

The HVAC condenser service and repair procedure starts with removing 2 bolts and 2 condenser bracket collars from the No. 1 condenser bracket collar. The first task requires a 14 mm socket hexagon wrench to detach the modulator cap and extract its O-ring seal from the cap. Pliers should be used to extract the cooler dryer. Installation of the cooler dryer requires pliers and proper application of ND-OIL 8 or equivalent compressor oil on a fresh O-ring before placing it to the cap. A 14 mm socket hexagon wrench is used to reinstall the modulator cap after it reaches a torque of 2.9 N.m (29 kgf.cm, 25 in.lbf). The installation process requires final attachment of the 2 condenser bracket collars with 2 bolts which need a torque force of 3.9 N.m (40 kgf.cm, 35 in.lbf).

Install it with 2 bolts, torqued to 3.9 Nm (40 kgf.cm, 35 in.lbf).

Use pliers to remove the cooler dryer.

Disconnect the liquid tube sub-assembly by removing the bolt and O-ring, also sealing the openings with vinyl tape.
