Ford Explorer A/C Hoses and Fittings

Regular maintenance can extend the life of your Ford Explorer vehicle. Replacing and repairing the A/C hoses and fittings can keep your vehicle cool during the hot summer months. Understanding how to locate and replace your A/C hoses and fittings is critical for optimum performance.

Are there different types of hydraulic hoses and fittings?

In any automobile engine, the air conditioning system is a highly specialized unit with a number of different hydraulic hoses and fittings. Some of the most common include:

  • The suction/discharge manifold hose, which is attached to the compressor. It has an aluminum manifold core reinforced by rubber hoses.
  • A discharge hose that connects the compressor to the condenser.
  • A liquid line, which moves liquid freon from the condenser to a receiver dryer, fixed orifice tube, or expansion valve, depending on what type of air conditioning system is used in the vehicle.
How do you measure the fittings on a hydraulic hose?

Using a special tool called a thread pitch gauge, you place the gauge on the threaded part of the fitting to measure the threads. The gauge will allow you to measure the threads per inch on the fitting for domestic cars; for foreign cars using metric measurements, you will measure the distance between threads for fitting. Also, you will need to check the fittings themselves for what type of connection the fitting has. Common automotive hydraulic fittings include:

  • Male or female fittings.
  • North American, German, Japanese, British, and ISO.
  • Tapered, straight, JIC, or SAE flare.
How do you crimp the Ford Explorer’s hydraulic hose?

Crimping a hydraulic hose for fitting onto your Ford Explorers air conditioning system requires the use of a specialized machine and a die and collar. To crimp a hydraulic hose, wear protective safety gear, such as goggles and gloves, and follow these steps:

  • Measure and cut the length of hose you need.
  • Using a fitting lubricant, push the fitting onto the hose as far as possible, then mark the location with chalk.
  • Choose a die that matches the diameter of your hose.
  • Set the machine to the correct micrometer setting for your hose.
  • Put the hose in the machine, add the compression ring on top of the die, and turn on the machine to crimp the hose.
How do you know if your A/C hoses need replacing?

The first reason you may need to check your Ford Explorer A/C hoses is a simple as the air conditioning in your car failing to work. If no cold air is blowing through the vents, check the hoses for signs of wear and tear or any leaks or holes. You should also check the fittings for cracking. Signs of leaks in the hoses include seeing traces of or drips of refrigerant on the hose lines.
