Entirely true - in fact this is what my shop did a few days ago with my brand new CVC comp. Flushed system, 5 oz of oil straight into the drain hole, nose down for a minute, clutch hub turned 10 times by hand, then charged it up and fired it up. Purring like a kitten at idle now (noisy when revved o...

My advice is to take the car to a shop equipped with the appropriate equipment. Cans are shadow tree-ish and inaccurate and the proper refrigerant charge amount being there right as the compressor shaft starts turning is crucial to minimize wear during a compressor run-in procedure (=anytime you add...

Yes, OP should expect to find very little oil inside it too. Running the A/C with way low refrigerant (the typical "something's hissing under the dash when AC/defroster is on" condition) is what sends most of the oil to the evaporator. Having a TXV means that the compressor is able to run ...

Do yourself a favor, flush the system, get a new dryer fitted and start with a system oil charge inside the compressor. Any commercial double end capped PAG 46 oil will be more than enough, no need for ZXL100PG or Ford's stuff. The risk of getting too much oil inside and suffering warmer vent temps ...

As long as you're using an evaporative flush solvent, chasing it with a lot of dry compressed air (or even better OFN) and then doing a good vacuum you should be fine. Ideally speaking, a flush solvent has to be evaporative so that it's easily removed from the system. If you flush the condenser too ...

The expansion device is an orifice tube. These tubes have two screens which can clog up. This is the only way one of them can can go bad. Expansion valves tend to interfere with pressure based evaporator temperature control systems (such as cycling switches) unless they're carefully tailored to the ...

It has only been checked by gauges. How do the check refrigerant weight? Would they evacuate the system then put in specified weight? Then they didn't check the refrigerant charge weight AT ALL. Refrigerant charge weight is checked by recovering whatever's left in a system and weighing it. My advic...

Hello all, I had the R134 checked twice and it is full and pressures are fine. Before dismissing it with "It's normal since it's a cycling clutch orifice tube system", which sounds like what a shop would say when giving the runaround, are you sure that the actual refrigerant charge weight...

The first thing to do when you have most AC problems is to verify the correct charge.. and thus eliminate that as a problem. Gospel truth. Unfortunately enough, too many owners feel too cheap (or lack the money needed for proper car maintenance in general) to either get the equipment needed (and th...

Maybe the evap is freezing up once compressor capacity climbs up enough? Does the air flow suddenly and eventually reduce?
