Year: 2002
Make: Chevrolet
Model: Tahoe
Engine Size: 5.3 Flex
Refrigerant Type: R-134a
Ambient Temp: 100
Country of Origin: United States

I recently bought a new compressor for my Tahoe. It is manufactured by "Tough One".

I am confused about adding oil to the compressor. The documentation gives instructions on how to fill the compressor with oil, but the following note appears at the end of the paragraph. "This A/C Compressor has been pre-filled with PAG Oil. Do not drain. Add the correct type and amount per your system specifications."

If the compressor has been pre-filled, do I need to add oil? If so, how much? The documentation does not specificy the amount of oil already in the compressor.

Thanks for any help that you can provide.

Thanks,

Justin

Best to call your vendor and ask them to clarify the procedure.

Thanks for the reply. I may regret buying this compressor, as I have tried to reach the manufaturer to no avail. I will probably end up draining the oil in the compressor so that I can add a known amount back to it.


Thanks

Probably a good plan.

It is always best to 'drain and refill' than to trust someone working on an assembly line. One never knows how much is in the compressor...nor the type...nor the quality (which will be the least expensive lubricant available).
Drain and refill.
However, this is the first of many questions concerning this repair. A simple compressor only repair may not be the best approach to insure cold air from the vents for an extended period of time.
Post a bit more about your OE failure and your path to a successful repair. Let us offer some, possible cash and labor saving advice.
Not sure who supplies 'Tough One' compressors.....they are not a known manufacturer....more than likely a 're boxer'.

Tough One compressors are supplied by Advance Auto Parts. They are using 4 Seasons part numbers supplemented by the 'T' prefix. It is quite possible that these are indeed 4 Season compressors...or they could be a simple line item purchase made by Advance. If this is so, there is a very good possibility that these are low price off shore units. Insure that the units are warranted by your supplier. Have seen some good stuff and some bad stuff coming from across the seas. The vast majority of the 'off shore' units are truly acceptable units...after all most OE compressors are made 'over there'. However, there are 'good'...'better'...and....'best' that arrive here. If a company such as Advance is offering a 'second' line to their major supplier, 4 Season, it stands to reason they are 'price buying' to offer a 'price' driven product. Personally...would be a bit concerned. This unit is a Denso 'take off....and have seen some serious issues with some of these units. Incorrect bearing tolerances....results in a noisy unit...is the foremost problem.
Hope your product is not one of these.
Good luck!!!
