Honestly if your not sure were it is i wouldn't recommend trying to tackle it however if you follow the lines from your ac compressor you will find two fittings one will be the low side it is small and the other is the high side it is large the system is under large amounts of pressure from the Freon in the ac lines so the system will need to be drained by a shop with an ac recovery machine otherwise when you try and remove the fitting if it can be changed it will rip the threads out and shoot up in the air, if you have ever turned a wrench the rest is self explanatory.
