Where is the expansion valve on a car?

Average rating from 5 customers who received a Check Heating AC. An expansion valve is an AC component that is commonly found on many road going vehicles. It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the vehicle’s AC system.

How to tell if an expansion valve is bad?

Symptoms of a Bad or Failing Expansion Valve (Orifice Tube) 1 AC system performing worse than usual and blowing warm air. 2 Frost on AC evaporator or coming from the vents. 3 AC compressor constantly running.

Where is the EXP valve on a Chevy 1500?

That’s what made wonder which piece you were talking about, because you said you were looking in the evap area under the dash, & that’s where the exp valve is, rather than the o tube. Me and O’Reilly’s guys were specifically taking about and saying “orifice tube” and not “expansion valve” so don’t know why they would have thought I meant the later.

Where is the expansion valve on an evaporator coil?

Look for a plastic (usually) tab just inside the tubing leading into the evaporator coil housing. You can grip this with a pair of needle nosed pliers to pull the expansion valve (again, also called the orifice tube) from the tube.

Do you need to change the expansion valve on an AC unit?

Also, when changing the compressor, replacement of the expansion valve is usually a requirement for warranty coverage of the new compressor. Remove or discharge any remaining refrigerant from the AC system.

How much does it cost to replace an expansion valve?

At this point, you will need to replace your A/C expansion valve to fix the problem. The replacement cost of an A/C expansion valve is anywhere from $200 to $450. The parts cost itself will be between $100 and $200 while the labor costs will be between $100 and $300.

What happens when your a / C expansion valve goes bad?

You will notice when the A/C expansion valve goes bad because your air conditioning system will ultimately stop functioning properly. It will either produce less cool air or it won’t produce any cool air at all. At this point, you will need to replace your A/C expansion valve to fix the problem.

Where to look for a leak in a Chevy Tahoe?

You would have to pull the panel and look in there with a black light/UV light. Could be rear evaporator leaking which is inside the passenger side rear panel by the tailgate. You would have to pull the panel and look in there with a black light/UV light.

Can a bad expansion valve cause an AC compressor to run?

AC compressor constantly running. A constantly running compressor is another symptom of a possible problem with the AC expansion valve. If the AC expansion valve fails or sticks open, it will cause the compressor to pump refrigerant through the vehicle’s AC system, even when it may be undesirable for it to do so.

Where is the transmission on a Jaguar XJ6?

Transmissions are a four-speed automatic equipped with a lock-up torque converter. The transmission is mounted to the back of the engine, and power is transmitted to the fully independent rear axle through a two-piece propshaft.

What kind of engine does a Jaguar XJ6 have?

Models covered Jaguar XJ6 models with 3.2 litre (3239 cc), 3.6 litre (3590 cc) & 4.0 litre (3980 cc) six-cylinder in-line dohc petrol engines and automatic transmission

What kind of suspension does a Jaguar XJ6 have?

The rear suspension is an independent type suspension which also have coil spring/shock absorber assemblies and a lower control arm. The rear driveshaft acts as the upper control arm. Power-assisted Anti-lock Brake Systems (ABS) with four-wheel disc brakes are standard equipment on all Jaguar XJ6 models covered in this manual.

How does an expansion valve in an air conditioner work?

The expansion valve is designed to meter the flow of refrigerant based on the heat load it senses coming from the evaporator. It also changes the refrigerant from a liquid to a gas. A little more physics: when a liquid changes to a gas, it absorbs heat – lots of it.

Why does my Jaguar air conditioner need to be removed?

Any moisture in the system will freeze up at the expansion valve and will clog the system, so it has to be removed. Then, it’s back to the compressor, and the cycle starts over. Remember, anyone can perform mechanical work on an A/C system without a license, but no one is allowed to vent any refrigerant into the atmosphere.

Can a bad or failing expansion valve cause unmetered refrigerant?

Frost on AC evaporator or coming from the vents. Another symptom of a potential problem with the vehicle’s AC expansion valve or orifice tube is frost coming from the vehicle’s vents. If the AC evaporator or orifice tube malfunctions, it can cause refrigerant to flow unmetered through the vehicle’s AC system.

What to do if your expansion valve is failing?

If you suspect that your expansion valve or orifice tube may be having an issue, have the vehicle’s air conditioning inspected by a professional technician, such as one from YourMechanic, to determine if the car will need an AC expansion valve replacement or another repair.

Why does my air conditioner have an expansion valve?

When you set the air conditioner to a higher temperature, this causes more refrigerant to flow through the passageway. That is how the air is able to get colder. When the flow of refrigerant is regulated, it is basically metered by the A/C expansion valve.

What happens when an AC expansion valve fails?

AC compressor constantly running. If the AC expansion valve fails or sticks open, it will cause the compressor to pump refrigerant through the vehicle’s AC system, even when it may be undesirable for it to do so. This will put an additional strain on the compressor and associated AC components, making them more susceptible to premature failure.

How many lines does an expansion valve have?

The expansion valve will have at least two refrigerant lines going to it and may have a fine capillary tube as well. Some models have four lines that are held on by fastening plates.

What happens when an expansion valve goes bad?

When the expansion valve fails or has any issues, it can cause problems with the functionality and performance of the AC system. Usually a bad or failing AC expansion valve or orifice tube will produce a few symptoms that can alert the driver of a potential issue.
