The refrigerant carries heat from within the motor vehicle to the condenser. The condenser improvements the refrigerant from a gas to a liquid, which expels the warmth. Primarily, air is blown throughout a very chilly liquid.

Verify for Leaks

Leaks are typically effortless to detect, but they are incredibly challenging to fix. Most automobile offer merchants have a shiny dye that can be injected into the a/c process, which will reveal leaks. The can will have instructions for use.

There is also a valve that will reveal the PSI (kilos for every sq. inch) inside the system. If the leak is quite lousy, the method will have pretty minimal force or no force at all. However, do not examine for stress by inserting anything at all into the valve nozzle. This is termed "venting," and it is illegal.
