447500-4700 DENSO Cool Gear Expansion Valve For ACV40 88515-06070

Description:

To determine whether the expansion valve of a car needs to be replaced, the following methods can be used:

1. Check the pressure value: If the high pressure is below 1.3-1.7MPa or the low pressure is above 0.1-0.25MPa, it indicates that there is a problem with the expansion valve.

2. Observe abnormal phenomena: When the expansion valve of a car air conditioner is broken, it usually manifests as the low-pressure pipeline not freezing, the dry bottle frosting, the condenser frosting, the expansion valve or condenser not making a whistling sound, high-pressure and low-pressure abnormalities, high-pressure pipe temperature abnormalities, etc.

3. Check the condition of the refrigerant: If the low-pressure pipe is not frozen, it may be due to insufficient refrigerant. It is necessary to check and replenish the refrigerant, and perform vacuum treatment at the same time.

4. Check for blockages and leaks: Frosting on the drying bottle may be due to clogged or damaged pipeline filters, while frosting on the condenser may be due to refrigerant leakage caused by damaged condenser joints or conduits, requiring corresponding replacement or repair.

5. Pressure range judgment: At a temperature of 30 degrees Celsius, if the low-pressure side pressure is not around 40 PS and the high-pressure side pressure is not around 1.5 MPA within ten minutes after turning on the air conditioner, it may indicate that there is a problem with the expansion valve.
