A/C Hoses and Fittings for Nissan Frontier

If the air conditioning system in a Nissan Frontier pickup truck is malfunctioning, it may be caused by a damaged or dislodged hose. Because the hoses connect all of the major parts of a Nissans AC system, when they become damaged, it has a big impact on functionality. Nissan Frontier drivers dealing with faulty AC hoses may need to purchase and install replacement parts.

The major components in a Nissan Frontiers AC system include the compressor, the condenser, the evaporator, the expansion valve, and the accumulator. Together, these parts remove the heat from air in a multi-step process. This process also requires refrigerant, a fluid that is designed to absorb heat. The hoses are primarily responsible for carrying the refrigerant from one part to the next. If they start to leak, the air conditioning parts may not receive enough of this cooling liquid to function appropriately.

There are several types of hoses that carry refrigerating liquid throughout the AC system. They include:

• Low-pressure AC hose: The low pressure hoses carry refrigerant while it is in a gaseous state. They usually connect the evaporator and the compressor. These hoses have to pass through the engine compartment, so theyre constructed out of durable materials like rubber. Theyre often subjected to extremely high temperatures in the engine compartment, however, which can cause abrasions or holes. This is a common reason for hose malfunction.
• High-pressure AC hose: These hoses carry refrigerant while it is in a liquid form, and they connect the condenser and dryer. When theyre in use, these hoses contain high pressure substances, which can cause damage over time.

In the Nissan Frontier, the AC hoses are secured to the major AC parts with metal fittings. When drivers are looking for new mounting fittings for their replacement parts, they should make sure the inner hose diameter, outer hose diameter, and connection size are all compatible.

When the hoses on a Nissan Frontier start to go bad, drivers may experience the following:

• Leaking: When AC hoses spring a leak, due to wear and tear or engine heat, drivers may not notice a puddle of liquid under their car. If they take a look at their air conditioning system, however, they will likely see drips and leaks along the hoses and fittings.
• No cold air: If Nissan drivers turn on the AC system and the air doesnt cool, it may be due to faulty hoses. If the other parts of the system arent getting enough refrigerating liquid, they wont be able to successfully remove heat from air.
