While driving on a hot sunny day, nothing can be more bothersome than a cooling system which does not do its job. When your car’s air-conditioning system fails to regulate the temperature, it’s probably because of a low refrigerant level.
Why Do You Need To Recharge Your Air-Conditioning?
AC is a closed system and coolant can’t reduce in volume. Neither can refrigerant escape unless there is a leak in your AC system. Leakage of refrigerant isn’t just an inconvenience for you; it’s also harmful to the environment.
So, you must be able to analyse whether your car’s refrigerant is leaking and decide when to head over for an Air Conditioning Recharge Wolverhampton. Below are a few ways you can diagnose your AC on your own.
Diagnose Faults With Your Car’s Air-Conditioning
Understand All The Parts Of Your Car’s Ac
Firstly, you should have a clear understanding of all the different components of your air conditioning system. The components of your car’s AC include a compressor, condenser, evaporator, and an expansion valve. Connecting all these components is a system of hoses, made of metal or rubber lines.
1. Prepare Yourself For Safety
You must take appropriate safety measures, viz. –
AC contains refrigerant in a state of high pressure, around 200 PSI.
Some parts of an AC system reaches over 65°C, so be cautious while touching any part of the system.
While diagnosing your AC’s components, you may need to access multiple components inside your car’s hood. If need be, you will also have to deal with these components while the engine runs. So be cautious!
2. Gather All The Right Materials:
Materials you will need are – Gloves, Wheel chocks, safety glass, and pressure gauge.
3. Set Up For The Check
Park your car on a flat plain area, and fix the wheel chocks on the driver’s side rear tyre.
Uncover the hood and locate the AC compressor. To identify the compressor, look for a large pulley near the front of your engine. This pulley will be driven by the engine drive belt. Also, a separate clutch will be present in the front of the compressor.
Turn on your AC and check if that compressor clutch, which was stationary before, is now engaged. After testing this, go inside your vehicle and turn your AC fan to medium. Check, whether the air coming from the dash vents is cold.
4. Pay Attention To These Outcomes.
The dash vents don’t eject any air. Airflow problem can be a result of blower motor issues or an electrical module failure.
Non-engagement of the compressor clutch
If there is low refrigerant in your AC system, the compressor clutch may not engage. Hence, you will need to determine the refrigerant level in the system.
5. Perform The Check
Turn your engine off and install the pressure gauge set. To do this, first, you’ll need to locate the high pressure and the low-pressure side of your AC system. Generally, you can find this low-pressure side on your passenger side and high-pressure side around the front section of your engine compartment. After locating the two ends, connect your pressure gauge’s terminals to these valves. Now notice the pressure reading on the dial. A reading below 50 PSI indicates a low refrigerant level.
Once you are sure that your AC is low on refrigerant, take it for an inspection. A car service in Wolverhampton is also an opportunity for you to get an AC inspection. Reputed garages such as Auto Surefit provide AC repair services. They also offer other car-related assistance such as oil change, clutch repair and MOT.
