Air chuck replacement

Definitely a compression fitting - designed to be unserviceable. Your first option is boring - get an assortment of O rings and see if any of them fit the need. You could get a barbed air chuck in ...

My AC compressors won't run, and the systems won't take a recharge. What should I check next?

Unless you're completely familiar with vehicle ac systems using all the equipment for diagnosing, troubleshooting and knowledgeable about repairs, your first mistake is using sealer; a no-no as you ...

Air chuck replacement

The joint at the end you're working with is a compression fitting and you'll not be able to remove it there. You might be able to remove it at the body of the air chuck, but I'd bet it'll break the ...

Sad, whiny, stressed out, constipated noise when AC is on. Is it dangerous?

I have actually seen an AC compressor on a 5.4 lock up so badly that the engine would no longer start. However, this was after the clutch had gone bad for a long time and the AC was not working at all ...

How to add compressor oil to an AC system that's already charged?

With AC compressor's lubrication there's no such thing as educated guessing. Even more if your compressor is of the vane or scroll type. Lack of lubrication, or, on the other extreme, hydrolocking, ...

How to add compressor oil to an AC system that's already charged?

You can use an oil injector on the low-side port while the car is running, fully-charged. That's the "suction" side of the system. Assuming you only changed a seal or hose, you don't need more than a ...

AC Compressor issues

A working AC is not a requirement for any time of the year, so you don't have to get it fixed at all. A working AC can be extremely useful for defogging your windshield as it dries the air in your car,...

Honda Civic 2006 AC clutch disengaging when warm

Possibly a weak clutch coil, whose windings have a high resistance that increases with temperature. You might also verify the clutch gap is correct, and the engagement surfaces are free of rust. You ...

What does tire size have to do with the capabilities of an air compressor?

Checking the spec sheet on line it appears the duty cycle of the Viair 84/85P Model is only 20 minutes. This is the reason for the tire size limitations. Basically they are trading off a low ...

Compressor Oil and Does It Need After Refrigereant Recover

Unless there is a new miracle machine, that answer is flat wrong. How does the machine "detect" the amount of oil charge shipped with the compressor? How does it know if the compressor is new, or ...

Using parts pullers for the installation

This is opinion-based: I'd go with a used part from a local wrecker. It is cheaper, and original quality is often better than aftermarket (rebuilt or new). For non-critical parts, which this is, it is ...

93-96 Honda Civic a/c problems

Looks like you have a high low-side and a low high-side pressure. This can be caused by too much refrigerant flowing into the evaporator, so it doesn't have room to expand (which is how the cooling ...

Is the AC compressor drawing a large load to the engine causing it to idle poorly?

A dirty throttle body can cause these symptoms. It is best to have it removed for cleaning. It is not possible to do a sufficient job without doing so. You can remove the throttle body and remove the ...

Is it time to replace the compressor clutch on my 2008 Mazda3?

IF the gauge is in the red when this happens, it's no the clutch. The high pressure switch is preventing the compressor from engaging. Fix the high pressure problem first.
