Question 1

How to remove the A/C Condenser from the HVAC system on Scion tC?

Accepted Answer

The procedure to remove the HVAC system condenser includes battery terminal cable disconnect and waiting at least 90 seconds to avoid activating Air Bags and seat belt pretensioners. The refrigeration system requires refrigerant discharge as the next step in the process. Disconnect the No. 1 cooler refrigerant discharge hose by removing the bolt attached to the hose and picking off the O-ring before covering the openings with vinyl tape. Sealing the disconnected part openings requires vinyl tape to stop both moisture and foreign matter from entering. Disconnect the cooler refrigerant liquid pipe through removal of its two bolts and the pipe before removing its O-ring and sealing the openings with tape. The process requires users to remove two bolts with accompanying brackets from the radiator support upper bracket. Unscrewing the 3 bolts together with the hood lock enables hood lock assembly removal. After that sequence remove the low pitched horn assembly and the high pitched horn assembly. The radiator support upper bracket requires removal by removing its 2 nuts and 5 bolts. To complete the procedure you must eliminate the cooler condenser assembly.

Question 2

How to disassemble and reassemble an A/C Condenser on Scion xB?

Accepted Answer

You must start condenser disassembly by removing two bolts together with the condenser bracket collars. Start by removing the cap from the modulator through its 14 mm socket hexagon wrench connection while taking out the existing O-ring from the cap. The removal of the cooler dryer requires pliers as an instrument. Install the cooler dryer using pliers then put a proper amount of compressor oil (ND-OIL 8 or equivalent) on both new and existing O-ring surfaces of the cap before O-ring placement. Apply 2.9 N.m (29 kgf.cm, 25 in.lbf) of torque to the modulator cap while installing it through use of the 14 mm socket hexagon wrench. Fasten the 2 condenser bracket collars with the 2 bolts while keeping torque at 3.9 N.m (40 kgf.cm, 35 in.lbf).

Question 3

How to properly remove and install an A/C Condenser on Scion xA?

Accepted Answer

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.
