Where is the low-pressure AC port located on the older model Mondeo?

The low-pressure AC port is located under the front hood of the Ford Mondeo, inside the engine compartment, between the coolant reservoir and the transmission. The high-pressure line is the AC pipe running from the compressor to the condenser, while the low-pressure line is the AC pipe connecting the evaporator to the compressor. Here is additional information: 1. The automotive air conditioning system is designed to cool, heat, ventilate, and purify the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. 2. For cars parked overnight or for an extended period, where the interior and exterior temperatures differ significantly, it is recommended to first open all doors, windows, and the sunroof. Turn the blower to its highest setting, activate the external circulation mode to expel stale air from the cabin, then close the windows and start the cooling/heating system while switching to internal circulation. This method allows for rapid adjustment of the cabin temperature, achieving quick cooling or heating effects. 3. Additionally, it is advisable to ventilate the cabin before driving a car that has been parked overnight. Due to volatile emissions from interior trim or other components, the air quality inside the cabin may be poor. Even if the temperature is comfortable, it is recommended to open the windows, turn on the AC blower and external circulation to exchange stale cabin air with fresh outside air before driving.
I've been driving an older Mondeo for years and have repaired the air conditioning several times myself. The low-pressure service port is located in the engine compartment, specifically at the front right corner near the firewall and battery. It's easy to find: after opening the hood, follow the thicker pipe until you see a valve with a blue cap marked 'L' or 'Low Pressure'. Last time my AC wasn't cooling, I solved it by adding refrigerant at this port. Remember to keep the engine running during inspection, otherwise the pressure reading won't be accurate. The location is somewhat hidden, but you can reach it with gloves on. Older cars often have seal leakage issues - don't force the cap open to avoid damage. I recommend keeping a pressure gauge handy for regular checks - it saves both money and hassle. If problems persist, don't push your luck; visit a professional shop for proper handling. After all, driving safety comes first.
