My high and low pressure r134 readings are 90-95 each.what should the refrigerant r134a high and low pressure readings be?
If the pressures are always equal running, the compressor is bad and would need replaced
Which side does the freon go into the high or low pressure end?
R134a goes into the low pressure port
Does a 2001 s10 have a different size input for r134a?
All r134a low pressure (suction) connections are the same size. All high pressure connections are the same size. The low and high connections do not interchange.
What is a good high pressure and low pressure for auto air conditioning using R134a?
20-30 on low side and 160-220 on high side depending on outside air temp.
What could varying blood pressure readings be a sign of?
It is totally normal for blood pressure readings to fluctuate throughout the day, even in healthy individuals. If readings are consistently high or low then the best advice would be to consult a doctor.
What is R134a low pressure and high pressure system off?
it depends on the surrounding air temp you need a pt chart for example at 90 degrees the standing pressure would be 105 psig
What is a good high pressure and lowe pressure for R134a?
ambient temperature X 2 + 50= good high pressure reading low should be between 30-40 for good reading may vary depending on ambient temperature
Where is the low pressure inlet for the air conditioning on a 3.4 L 1997 Venture?
It is in the last place you would think. P.s. Its in plane sight R12 Low Side 7/16 in. threaded ß----------à R134 Low Side 13mm Quick-disconnect R12 High Side 3/8 in. threaded ß----------à R134A High Side 16mm Quick-disconnect On older R12 systems, the LOW and HIGH pressure service fittings are screw-type Schrader valves. On newer R134a systems, the LOW and HIGH side service fittings are quick-connect style fittings. The LOW pressure fitting is SMALLER than the HIGH pressure fitting.
Does it move from an area of high pressure to low pressure or low pressure to high pressure?
A fluid will move from high pressure to low pressure.
Where is the low pressure port in your car?
There will be two. Generally the low pressure is mounted more towards the front of the car and will most likely have a blue cap on it. If it does not have a blue cap on it compare it with the high pressure port. The high pressure port (for r134a) will be wider with different threads where as the low pressure port will be slim. If you cannot find either search deeper with a flash light. Be careful to wait till the car has cooled, although you should not have to search too much as the low pressure port is generally easy to reach. Also, check the label on your car to make sure it is r134a coolant. If it says r12 you will need to take it in to have it charged with r12.
Where is the low pressure air conditioning service port on a 1990 buick lesabre?
I highly recommend taking it to a service station because you will need to have it retrofitted and the freon changed to r134a instead of r12 ---- DO NOT ADD r134a to r12 it will lock up your compressor ---- But the low pressure valve is the one closest to the firewall it will look like a tire valve stem. The high pressure is located closer to the ground.
Does a 1997 Chrysler Town and Country take R134a?
You can tell by looking at the high and low pressure service ports. The old r12 ports were smaller and threaded. The r134 are larger and are a quick-disconnect. Yes, a 1997 Town and Country uses R134a.
