TOYOTA FORTUNER aircon not cold?
Diagnosis: AC System leak
When your vehicle's AC system develops a refrigerant leak it can be challenging to detect due to the fact that refrigerant fluid instantly evaporates when it comes in contact with air. A professional mechanic uses specialized tools to determine if there is a leak by introducing nitrogen pressure or ultraviolet fluid to show signs of low refrigerant pressure in the AC system.
Signs of an AC system refrigerant leak:
* Audible click when the AC is turned on.
* AC cycles on and off frequently.
* Hissing sounds from the AC system
* Oil residue around AC pipe fittings and hoses.
A refrigerant leak repair may include repairing or replacing the specific failing component. If a large amount of fluid has been lost, your AC system will need to be flushed and the refrigerant fluid will need to be replaced to function properly and get the cool air flowing.
Solution: Correction of system leaks.
General AC cleaning with leak detection. Replaced Denso rear evaporator, expansion valve and drier. Flushed AC system. Top up compressor oil. Recharged freon on this ‘12 Toyota Fortuner.
