Get an Evo
I don't knew any airpressure clutch systems by cars. Only hydraulic coupling and maybe electric or electromagnetic ones by cars & trucks.(including electronic programming system-eps-by mb-trucks-that includes all kind of that stuff).
The system is likely a bit lor on refrigerant, BUT,
R134a systems in vehicles are charged up by the WEIGHT of the refrigerant, gauges are used to check compressor function. Also, ambient temperature plays a huge roll in pressure readings. At 65 degrees F, a typical gauge reading in a fully charged system might be 30/140, but if it were 95 degrees F, 45/260 would be about 'normal', and this is also @ 1,300-1,500 rpm, not idle.
The compressor is designed to compress gas into liquid, and overcharging the system, the refrigerant will be returning still liquid and slug the compressor, likely damaging it.
If the compressor for your car does not have an over-pressure relief valve, so an overcharged system can also rupture a line, condenser, or the evaporator core.
Unless all the refrigerant in the system is evacuated, and then added back by weight, you risk damage to the system.
Somewhere under the hood, is a sticker showing how many ounces of refrigerant the system holds.
If you're going to charge a low system without the right equipment or knowledge anyhow, get the engine up to 1,300 rpm, add a bit of R134a, and feel the aluminium low line by the dryer. When it gets moderately cold, stop.
This ain't the right way at all, but it's kinda accurate, where a gauge is not.
No
Get a manifold gauge and check pressure on both sides. Could be a bad TXV or the refrigerant charge is low or high.
Usually when an AC compressor keeps switching on and off the 134a charge is still too low. You should be getting 42 degrees Fahrenheit cold air out of the center vents.
Hi your problem is related to the age of the car and wear.
So?
You need a mechanic.
- Karcher Honda Pressure Washer 2400psi Low Pressure? Hello every one I have a Karcher Honda Pressure washer 2400psi, when every I pull the trigger the first time it works fine. Then when I take the vavle unloader and the end where the air filter is on the pump, it works after a while for only one trigger pull. What's wrong?
- Why does my AC fan and compressor clutch stay on and never cycles on and off when i have the AC ON? 2010 honda civic. Recently replaced the compressor because it was shot and i also have the right amount of refrigerant
- How Much cost to replace 2010 Honda Civic AC Compressor Clutch? I have a 2010 Honda Civic, It was running smoothly up till now, but the AC Compressor just destroyed itself this past Friday. Sounds like this is a honda civic common problem for the car? Either way, the dealership shop is quoting me $1,600 to replace the compressor, clutch, serpentine belt and for an AC recharge. Does this sound about right? Or am I getting hosed? i just noticed ac compressor and clutch for honda civic 2010 only need 108$ in HexAutoParts.com, is it reasonable?
- 97 Honda Civic, new clutch and pressure plate but won't come out of gear and clutch pedal won't release? The clutch feels backwards now, won't switch gears unless the car is off and the pedal is all the way up. When you start it in gear it will not come out of said gear unless you turn the car off. The clutch pedal will get stuck down and the car will roll in whatever gear you put it in, when putting the clutch pedal down is supposed to release the clutch… It does not
