How To Spot An A/C Leak In Your Porsche

Finding a leak in your Porsche A/C system can be difficult. It will depend on how big the leak is. If you happen to notice that the leak falls quickly, it will be easier to spot the leak just as you would when you feel like there is a hole in your Porsche tires. It can be a result of a blown hose rubbing through the bracket inside the engine. Wonder how you can find a leak in the A/C system? Here are tips to help you with.

Start with the Spray Bottle Method

Using a water spray bottle that has a heavy soap solution, you can spray the mixture around the A/C system components like Porsche A/C compressors. Do this only after you have fully charged the A/C. Bubbles are indications that there is a leak on that part. You have to take note though that you cannot use this method when you want to spot a leak in the evaporator or in the compression front seal.

Using a Leak Detector

You can always purchase a leak detector if you want to spot a leak yet you cannot spot oil residue or hear sounds of leak on the system. The leak detector has a main body where the batteries, on and off switch, sensitivity controls, and sensing device can be found. On the detector's end is a sniffer that is used to pull a certain amount of air. This will be used to analyze any traces of refrigerant that has been leaking in the system.

Leak Testing

Leak testing can be started only if the A/C system has been filled with Freon because if the system is flat, chances are, the detector's sniffer will not be able to detect anything. Turn off the car engine and make sure the car is parked in an area where there is no breeze or wind because wind can make it hard for you to detect the leak and even when you do detect a leak it can be a false reading resulting from the air movement pushing the Freon away.

Take Note of False Readings

Aside from air movement which can produce false reading, dust and dirt are also noted to affect the reading on the detector making you think there is a leak even though there is not or vice versa. Make sure the sniffer does not come in contact with dirt to prevent this from happening.

Start Detecting For Leaks

When operating a leak detector, you have to make it a point that you adjust its sensitivity to the lowest setting possible. From here, you can start testing on the receiver's O ring seal because this is a spot popular to leaks. The tester signals there is a leak when one or more red lights show on it. This is accompanied by a beeping sound. Adjust the sensitivity setting and run the necessary test until you have reached the highest setting and leak has been detected. You may want to further the search on the pressure sensor of the system. Check probability of leaks at the electrical connector and the base.
