Where to Find the Expansion Valve on a Volvo VNL – A Step by Step Guide

The expansion valve for a Volvo VNL is located on the top of the evaporator.

Volvo Vnl Expansion Valve Location

The Volvo VNL Expansion Valve is located beneath the compressor inlet tube. It is used to regulate the rate at which refrigerant flows from the condenser to the evaporator. This valve helps maintain optimum temperatures in the cab and cargo area, allowing for a comfortable driving experience. To access it, you must first remove the air intake manifold, located near the front of the truck. Once this has been completed, it should be easy to locate and inspect the valve. If needing to replace or adjust the valve, special tools are required to ensure it is properly secured in place without damaging any components or seals. Proper maintenance of this valve will ensure that your Volvo VNL runs at optimal performance levels for years to come!

Volvo Vnl Expansion Valve Location

Volvo VNL expansion valves are located in the engine compartment and are designed to help maintain the correct pressure for the air conditioning system. The expansion valve is a critical component of the air conditioning system, as it helps maintain the proper pressure and temperature of the refrigerant so that it can be used effectively throughout the system. The expansion valve is responsible for controlling the flow of refrigerant as it enters and exits the evaporator core, which is responsible for cooling down and condensing the refrigerant.

Volvo VNL trucks with an expansion valve include models such as:

• VNL 300 Series This model features a 7-liter engine and an 8-speed transmission.
• VNL 630 Series This model has a 13-liter engine option, along with an automated manual transmission.
• VNL 730 Series This model has a 16-liter engine option and can be fitted with either a manual or automated manual transmission.
• VNL 780 Series This model has an 18-liter engine option, along with either manual or automated manual transmission.

An overview of expansion valves shows that they are used in various applications. They are used in automotive air conditioning systems to control the flow of refrigerant by regulating its pressure and temperature. Expansion valves come in different types such as fixed orifice, adjustable orifice, diaphragm type, solenoid type, etc. They also come in different sizes and are made from various materials such as copper, brass, plastic, etc., depending on their application.

The main components of an expansion valve include its valve housing, valve body and seals. The valve housing is responsible for protecting all parts from corrosion while also helping direct airflow into and out of the evaporator core. The valve body helps regulate pressure within the system by controlling how much refrigerant is allowed to enter or exit at any given time. Finally, seals help maintain a tight seal between all parts to prevent any leaks from occurring.

Signs of malfunctioning expansion valves include: reduced airflow from vents; uneven cooling distribution; strange noises coming from under hood; unusual odors coming from under hood; reduced fuel economy; lack of cool air coming out when A/C is turned on; fluid leaking under vehicle; higher than normal temperatures inside cabin; increased compressor cycling time; and decreased cooling performance overall. If any of these symptoms occur it is important to have your vehicle inspected by a certified mechanic as soon as possible to determine what repairs may be necessary. Depending on the severity of any damage that may have occurred due to malfunctioning parts, solutions may range from simple repairs all the way up to complete replacement of faulty components.
