Re: Driving car with VDC and no refrigerant

b] The dealer's service writer said there would be no problem driving the car while we wait for parts, as long as we didn't turn the AC on. Okay, it's not summer anymore, but doesn't the compressor want to be on in DEFROST setting? Supposedly the system won't try and turn on the compressor if it's ...

But it sounds like it's not a problem, Thank You guys!
Not unless the clutch is engaged.

Re: Driving car with VDC and no refrigerant

It's all irrelevant, if your charge is gone, low pressure switch won't allow compressor to even start so it's not going come ON no matter what.

Re: Pressure testing a compressor

I held the top case section with a strap wrench to remove the mounting flange only. The put a seal protector over the shaft trying to save/reuse the seal. I forgot that there is hole which the shaft passes through behind the seal a short distance. Using a gear puller on the end of the seal protector...

Re: Pressure testing a compressor

More confusion! Another short YouTube video of the compressor with 200psi of nitrogen on it showing dye leaks which showed up when submerged in water. Compared to my other video above, leaks show under one condition but not under others! :roll:

Re: Pressure testing a compressor

Here's some highlight excerpts from a unlisted YouTube video I did on testing my HR6. It was charged with refrigerant and heated with a tank heating blanket which is supposed to go to 125F but unsure it did get that high as it cycled frequently. Leaks came/went as it heated up and cooled down. https...

Re: Pressure testing a compressor

Before installing the compressor would hold 150psi over night but would lose a few psi at 200psi but I thought, how long or how often with it be 200psi while in use?? I installed it. It held 100psi but lost a little at 150psi of nitrogen. Using a liquid leak detector, I couldn't find any leaks. I of...

Re: 2006 Jeep Wrangler Recharge problem

Just like mk378 stated, your low side Schrader valve isn't being open by your coupler. The 72psi is just what flowed from the refrigerant tank up to the low side Schrader valve. My gauge set couplers have a built in on/off valve so I won't run into that problem. Are you sure your's aren't adjustable...

mk378 wrote:Whenever someone reports they see the high side a lower pressure than the low side, that almost always means that the couplers on their manifold aren't engaging the ports on the car properly.
That's only 7psi difference and all analog gauges are more accurate in the middle third of their scale.
