Where is the low pressure side of ac on a 2005 ford focus?

On a 2005 Ford Focus, the low-pressure side of the AC system is typically located at the smaller of the two AC lines near the compressor. It's usually a thinner diameter line and will be connected to the evaporator. Look for a service port (a valve with a cap) on that smaller line. This port is where you'd connect gauges to check refrigerant pressure.

Important Note: While this is a general location, the exact placement can vary slightly depending on the specific trim level and configuration of your vehicle. It's always best to consult a repair manual specific to your 2005 Ford Focus for precise identification. Working with refrigerant requires specialized knowledge and equipment. If you're not comfortable working on automotive AC systems, it's best to take your vehicle to a qualified mechanic.
