How do I know if I have a bad expansion valve?
Symptoms of a Bad or Failing Expansion Valve (Orifice Tube)
- AC system performing worse than usual and blowing warm air. One of the first symptoms of a problem with the AC expansion valve or orifice tube is an underperforming AC system.
- Frost on AC evaporator or coming from the vents.
- AC compressor constantly running.
Can you replace expansion valve?
The good news is that, as you’ll find out here in a few seconds, replacing a bad AC expansion valve is a whole lot less expensive than replacing many of the other components found in your car’s AC system.
What happens when expansion valve sticks open?
If the expansion valve is stuck open or clogged, the AC system will not cool properly. A clogged valve will lead to too little refrigerant, increasing the pressure in the system and causing the AC compressor to overheat.
How do you remove an expansion valve from a car?
The one thing I would add is that you can remove the evaporator core/expansion valve assembly entirely from inside the car (internally there are 10 mm bolts connected to the aluminum coupler that sits in the firewall. Remove these bolts to pull the “cooling lines” away from the firewall and remove the evaporator assembly).
