Model: G20- Sportvan
Engine Size: 5.7
Refrigerant Type: r1341a
I have a new expansion valve that I will be installing on my rear ac in my Chevy van. It has been a few weeks since I removed the original and cannot remember how to reinstall the new valve. Here is a picture of the old one - I know where it physically goes on the unit, I just cannot remember if the small coil at the end was clamped to the inlet or the outlet. Which one does it get clamped to? (I have a little stainless steel spring clamp that holds it in place). Thanks in advance!
Coil clamps to the outlet, the pipe that gets cold while it is running- that is how it monitors the system......
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
Thanks - that's what I figured... but my "figuring" is not always correct!
Make sure the coil end is wrapped completely with prestite tape or similar material. You have to have a correct reading for the valve to operate correctly.
