Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Air Conditioning: Notes
There are five main components in the climate control system:
- evaporator
- receiver
- compressor
- condenser
- throttle valve.
The system is filled with a suitable quantity of refrigerant and oil. The role of the oil is to lubricate and seal the compressor (piston and cylinder). A fluorescent leak-tracing agent is added to the refrigerant. This makes it possible to trace leaks using UV light.
In vehicles with the B418S11 engine the compressor is located on the rear edge of the engine. In vehicles with other engine variants the compressor is located on the front edge of the engine.
