No car owner ever wants to hear the word ‘leak’. It doesn’t matter what you could be referring to. So when you suspect your car’s A/C system has a leak, you have all the reasons to worry. Of course you can fix the problem, like it is often the case with other leaking problems. What often causes a stir is how the leaking can happen without your knowledge. In other words, it is good to identify the tale tell signs of a leaking A/C system. This should be easy even for a first time car owner. If the system is flat or you have to continuously recharge it, then there is a high likelihood that the system has a leak. Here’s what it takes to know if there’s an A/C leak in your Volvo.
The Bubble Method
It is the most effective alternative method to using a leak detector. Charge the A/C system fully. Then fill a water spray bottle with a soap solution. Make sure the soap solution is heavy enough to create bubbles with ease. Spray around different components of the A/C. Bubbles will form around a leaking area, so you will know the exact spot that’s problematic. Note that this method works well except for evaporator leak detection and the compressor front seal.
Slow leaks can be stubborn and hard to find. If you’re keen enough though, you can visually see small leaks mostly because of the peg oil inside the A/C system which often leaks together with the refrigerant. The oil seepage is the exact spot where the leak is located. Remember to examine all the refrigerant lines as well as the condenser and the compressor to note any signs of leakage.
They come in handy when you cannot find any oil residue or you simply cannot hear the leak. It gets better with the fact that most detectors sell for less than $40. The detector, which made up of a main body designed to hold a sensing device powered by a battery is always accurate. It has a ‘sniffer’ at the end which is where it pulls a small amount of air for analysis and traces of leaking refrigerant. This saves time and money. That explains why it is a highly recommended method. Remember that the leak detector is durable so you can use it for a long time.
Point To Note
The detector will not show anything if the system is low or completely flat, so charge it before running the detector. The car must also be off and parked in a place with minimum breeze or wind. That’s because too much air movement can easily push the detectors Freon away from where the leak is. This will make detection hard for you. Another point worth noting is that the refrigerant is heavier than air. With that in mind, do the leak test from the bottom. Be sure to also read the instruction manual that comes along with the detector.
