●COLD LOOP COMPONENTS
–Compressor: This is located at the bottom on the left-hand side, next to the radiator in the engine compartment.
–Condenser: This is located between the radiator and the cooling fan assembly.
–Dehydrator reservoir: This is located on the left-hand side of the condenser outlet.
–Heating and air conditioning unit: This is located under the dashboard.
–Thermostatic expansion valve: This is located to the left of the heating and air conditioning unit on the
bulkhead.
–Evaporator: This is located to the right of the thermostatic expansion valve in the heating and air conditioning
unit.
–High pressure pipe: This pipe connects the compressor, condenser, dehydrator reservoir, and expansion valve
inlet in series (it is located in the engine compartment on the left-hand side).
–Low pressure pipe: This pipe connects the expansion valve, buffering capacity, evaporator, and compressor
inlet in series (it is located in the engine compartment on the left-hand side).
