It is all import parts anyway, and the 2004 Nissan was the end of the V belt compressor. So by now any new compressor is an import from a 3rd party supplier - and WHO you buy it from is more important than where it was made. If you buy from a reputable supplier that will be there tomorrow, they are ...

The good news: the AC idler pulley is fine, the AC clutch is fine, the Gates AC belt is fine.

The bad news is that the compressor is locked up tighter than a drum. This Frontier uses a DKV14C Compressor; and since the condenser is parallel path type, that will need to be replaced too, as any ...

The 2004 Frontier AC stopped working today while driving on the freeway, first symptom was a bad squeal which disappeared when I shut off the AC button. But the belt doesn't feel loose, and no sound when AC is "off", so not sure it's the idler either. Because the AC wasn't cooling after that, the ...

Maybe 2 years ago I replaced the compressor in our 2005 Yukon with 6.0 liter (did not have an A6) and that went smoothly; that's my only experience with a GM in recent years.

I added oil containing UV dye, pulled good vacuum, checked for leakdown, purged service gauge lines, let refrigerant enter ...

Also, what are you accomplishing when you break in the compressor by turning the input shaft several revolutions before you install it ?

Rotating the compressor center distributes the oil somewhat, gets it out of the compressor (important)- which cannot compress liquids, just gases. So add the ...

Thanks. This is only when I tighten the nut. It sits flush by hand. Single oring in the groove

Hmmm- your O-ring channel is shallower than the one pictured on my Frontier in my earlier post. The Frontier O-ring stays in its channel ...

Measure the depth of the fitting, and measure the depth inside the accumulator hole, to make sure that it CAN fit flush. Even try without the O-ring to see if it sits flush.

Last year I bought a replacement high pressure AC line for my 1998 Frontier, the cylindrical fitting on the aftermarket ...

Post pressures at 1500 - 2000 rpm.

Also check to make sure no heated air or outside air is getting mixed in.

I think that some people rent those pumps from AutoZone, use them improperly (causing oil to spill) and then they run them while low or out of oil. This obviously causes irreparable damage to the pump.


Last year, I was 100 miles from my own vacuum pump. I got the free loaner vacuum pump from ...
