Refrigerant Type: R134a

I am new to AC repair . On an 04 Impala, I am replacing the condenser, because of a hole and want to replace the accumulator. How do I remove the black covers over the accumulator line connections?

Actually, the part is not an accumulator, it is a receiver/dehydrator- you have a TXV system- so receiver is on the high side, not like an accumulator system, where it is on the low side. Perhaps you can be more specific, a photo even of what you are having trouble with.

As I recall the receiver has hoses permanently attached to it and receiver and hose assembly is replaced as one assembly. Look it up on any parts website, and you'll see what the replacement looks like. Lots of times it is easier to see how to do a job once you see the replacement part.

I looked again- you need to insert a flat bladed screwdriver in the tab slots to release the clam shell connector

-------------------------
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......
