If you’re not familiar with the location of this important part, you can find it on your vehicle’s 4.2L engine. It’s a small, hidden port above the fuel rail on the passenger side. It’s angled toward the drivers side and is surrounded by a plastic cover. For a better view of the low pressure port on your vehicle, check out the Haynes manual.
Most vehicles have a low pressure port in their HVAC system. It connects a can of refrigerant to the low pressure port, and the compressor will add the freon once the vehicle is at the correct pressure. HVAC leaks are common problems on most vehicles. To fix this problem, make sure the vehicle has a proper pressure gauge and is fully charged. It will also be helpful to check the refrigerant level by utilizing a gauge.

How Do You Put Freon in a 1999 Ford F150?
Adding refrigerant to a car’s air conditioner is a common home repair project. If your 1999 Ford F-150 is experiencing bad cooling, you can re-charge the system to restore the cooling capacity. Most refrigerants come with a leak sealer to prevent further damage. Make sure you have the correct amount of refrigerant for your car by reading your air conditioning gauges.
The hoses come with a red and blue fitting. Attach the red hose fitting to the high pressure port and the blue hose fitting to the low pressure port. Using the correct hose is essential to avoid damaging the needle or releasing freon into the air. If you don’t understand how to do this, don’t try it. You might end up releasing freon into the air and may even damage your car.
Where is the Low Pressure Service Port?
The Low Pressure Service Port on a 1999 Ford is on the engine compartment firewall, close to the accumulator. The port is the larger of the two hoses that lead to the compressor. Once connected, the compressor will add the required amount of freon and restore your vehicle’s air conditioning system to normal operating pressure. However, adding freon won’t repair the problem with the compressor or evaporator.
The low side service port is on the passenger side, near the fuel canister. It’s hidden and somewhat angled to the drivers side. A Haynes manual can show you exactly where to find this part. Once you find it, you’ll be ready to hook up gauges. Ensure that you disconnect the air-conditioning hose first, then reconnect the fuel line.

You will find it on the passenger side, a little to the left of center on the firewall.
Where Do You Put Freon in a 2001 Ford F150?
To replace your air conditioner’s refrigerant, follow these steps. To start, locate the low-side service valve on the compressor. Push the recharge hose onto the valve, and then connect it to the lower-side fitting. Hold the r134a can upright to ensure maximum flow. Press the valve to release the refrigerant. The compressor will add the required amount of freon and then turn off the engine.
To replace the AC, drain the oil from the accumulator and then measure the liquid ounces. To replace the oem lubricant, Ford uses a synthetic polyalkylene glycol lubricant, and most vehicles require about 25 to 35 lbs. R134 is around 80 percent of its original capacity. Remember not to over-charge the compressor; excessive recharging can damage the compressor.
How Do You Put Freon in a Ford F150?
If you want to learn how to put Freon in a 1999 Ford truck, you will need to know how to disconnect the air conditioning system and then reconnect it. First, find the service port on the engine bay. It should be covered by a black plastic cap. Then, you will need to find the R-134a recharge system. Open the service port and attach the R-134a can to the lower side of the valve. Start the engine. Then, follow the rest of the instructions for the rest of the process.
Next, locate the accumulator, also known as the receiver/dryer. This black cylinder is located against the firewall on the passenger side of the truck. Locate the low pressure port. Unscrew it three to four turns to make sure the freon travels from the can to the suction side. The vapor management valve is located on the side of the accumulator. It is part of the emission controls and refrigerant recovery system.
Do You Charge AC on High Or Low Side?
Whether your AC is charging on the high or low side depends on what your car’s brand and model is. If your AC is charging on the high side, it may have issues. The compressor in your car could be malfunctioning. When you see the high side gauge, you can immediately diagnose the problem and fix it. If your AC is charging on the low side, there are several things to do before the system breaks down.
Ensure that the refrigerant can is properly charged. While the low-pressure port is often preferred, there are times when charging on the high-side can be hazardous. The best time to do this is when the temperature is between 75 degrees. Using this method can result in valves breaking and oil leaking from the sump. When you do it yourself, follow the directions carefully to avoid damage.
Which Line is Low Side on AC?
If you’ve recently serviced your AC system and are wondering Which Line is Low Side on a 1997 Ford F150, you need to know which side the compressor port is on.

The low side service port is located on the side of the accumulator can, which is near the firewall slightly to the passenger side.
When replacing the air conditioning system in your 1999 Ford F150, first check that you’re using the proper refrigerant. The air conditioning system is made up of a belt-driven compressor and an evaporator. Adding more freon will not fix problems with the compressor or evaporator. It’s better to replace the entire system with new, fully charged refrigerant than to try to fix a leaky compressor.
