Car Air Conditioning

To locate even the very smallest leak in a vehicle’s air conditioning system Precision Motorcare use a “tracer gas” which contains a small amount of highly detectable hydro-carbon, using a device which can easily pick up this “tracer gas”. Using this method even the tiniest leaks can be identified.

This process is usually completed in under an hour unless your particular car or van has difficult-to-access air conditioning components.

Firstly, and most importantly, this method of finding leaks in your car or van’s air conditioning system must NEVER be carried out using compressed air. If it is, moisture will be introduced into the air conditioning system which can be extremely dangerous, and possibly incendiary.

For larger air conditioning system leads, normally, pressure testing (with nitrogen) is all that is required. Precision Motorcare will pressurise the air conditioning system using an inert gas (OFN -oxygen-free nitrogen) and then listen for the sound of escaping air, or use a bubble spray, to locate the leak. This method is fast and inexpensive but can only be used to find larger leaks.

Ultra-violet (UV) dye testing is an alternative method for finding small air conditioning leaks. During this method, UV dye is injected into the air conditioning system along with the refrigerant. The refrigerant transports the dye around the system which is visible using a UV light wherever there is a leak.

But we must always bear in mind this method can only be used in an air conditioning system which hasn’t already leaked refrigerant; it is against the law to put refrigerant into an air conditioning system where there is a known leak.

When Precision Motorcare regas a vehicle’s air conditioning system we will always put UV dye in with the refrigerant as standard so that leaks can be found easily at any time in the future.
