I agree. You might get lucky but you could also end up chasing your tail, with freeze up problems, and stuck Tx valve from moisture in the system.

If it doesn't have a core, there is going to be no way to take your hose off and change the fitting or install a core. There are tools that let you swap...

[Cornbinder89]

All I'm saying is if you don't get to the source of the problem it will continue to cause problems in the system. It is your eyes on the system, you have...

[Cornbinder89]

It seams like you have contaminates though out the system. Tx valves don't "open or close" they are always a restriction, sometime a larger...

[Cornbinder89]

Yeah, that one threw me until I was able to read the manual. I think it was a Nissan, and it was most defiantly a Tx valve system, so shouldn't have "cycled"...

A coupla years ago I found out that some mfg have a high pressure cut-out that varies depending on if the car is stationary or moving! Yep, different...

[Cornbinder89]

Done that more than once, Put the hoses under the windshield wiper to hold it in place. It will answer some of your questions about what is shutting the...

[Cornbinder89]

Most cars, esp those with small engines, have a throttle cut-off switch that kill the compressor when high throttle setting (WOT) is called for....

Forget that chart, it shows what someone thinks it should read.

If it were mine, I'd pull the compressor, pull the clutch, and if nothing seamed out of place, disassemble the compressor to find the source of the failure,...

[Cornbinder89]

From what I see, the compressor isn't doing anything. However, the condenser will need to be changed if the compressor has shed metal into the system....

[Cornbinder89]

At very least, you need to separate the liquid line at the orifice tube and inspect the screen on the tube. Failure to remove any debris in the system...

[Cornbinder89]

Is the compressor clutch cycling? If not you could have a bad (leaking) valve in the compressor or a slipping clutch. From you description I don't see...

[Cornbinder89]

There are several types of valve cores, The std one like a tire uses is common, but there are several "high flow" types, so you will need to...

[Cornbinder89]

Let us know how it turns out please!

[Cornbinder89]

I'd say 1st thing is to see if you can find a spec for the clutch gap, barring that I'd try and get it down to .015". Leave the charge amount alone...

[Cornbinder89]

We all learn by making mistakes. I have always said, I can do it wrong, learn and do it over for less than paying for someone else to do it. But you have...

[Cornbinder89]

No oil is why the old compressor packed it in. For an overcharge to damage the compressor it would have to be so much over that liquid refrigerant was...

[Cornbinder89]

So, re reading this, you drained all the oil out of the compressor, put some back in the condenser, and than ran it? What the heck was the compressor...

[Cornbinder89]

Tx valves don't "open or close" they are a variable restriction. If the pressures were equal with the compressor turning then the compressor...
