Year: 2000
Make: Chrysler
Model: Voyager
Engine Size: 3.3L
Refrigerant Type: R-134
Country of Origin: United States

How much pag oil is required for the ac system of a 2000 Grand Voyager SE, with front and rear air. The compressor is to be replaced and a complete flush of the system will be performed.


Any tips or tricks would also be appreciated.

Thanks

Jim

I show 13oz of Pag 46 on a fresh system. What else is being replaced along with the compressor and what is being flushed?

I am replacing the drier and flushing the hoses, both evaporators and the main and aux condensers. (compressor is frozen. will replace other components if needed once they are examined)

Thanks

The compressor and drier are only the start of it. You will need to replace the orifice tube since it is probably full of debris, the rear expansion valve because it cannot be flushed through and there is only 1 condenser. You will need to replace that as well unless the shop performing the repairs has the proper machine to do it. Which the vast majority of shops don't. You will then need to isolate the individual components and flush them seperately. There is no real way to examine a condenser, when a compressor goes out, the condenser is the first thing that fills with debris and because of the design, is very difficult to flush. The orifice tube should be replaced if there is any debris on it, which during a compressor failure there will be plenty. The expansion valve has to be removed to flush the rear evaporator and may have debris in it as well so replacement is recommended.

This is a really great forum, I am very impressed.

Where is the orifice tube located? I am a bit confused with the condenser. I am showing that there is a primary and smaller auxiliary condenser for the Grand Voyager with rear air.

It sounds like I need a few more parts, not a problem although it would be nice not to have to spend so much.

Is there any special instructions for adding the PAG oil? It sounds like a add a bit to the compressor and some to the drier.

Thank You

This system uses an expansion block not an OT.
