That's them, and only ones, there's an orfic tube in between both ports in the line, that's what changes the pressure from high to low, from one end of the orfic tube to the other, the small port will be the low side, that the one you recharge in, and the big one is high side.Hope this was very helpful.

On A/C, there are only 2 ports. One smaller than the other. The small port is your suction (low side) port. The larger is the high side port) You can only charge the system through the low side port.

Which port is the low side port for ac charging on 1997 gmc jimmy


The low side port is always the smaller fitting on the larger line. The high side is always the larger fitting on the smaller line. They do this so that the low side fitting can not be mixed up and placed on a high side port.

Where is the low pressure port on a '08 town and country LX V6 Flex fuel? trying to recharge a/c ..i found two dust caps, but unable to identify low port.


the low pressure port is always the smaller fitting on the larger line. The high pressure port is always the larger fitting on the smaller line. They do this so that it is impossible to place the low pressure fitting on the high pressure port.

Where is low side port for recharging a/c. on my 1997 s10. I found 2 ports one on the accumulator and one on the tube, however my charging kit port only fit the port on the accumulator. I assume this port...


The port on the accumulator is the low side. The high side port is smaller than the low side. The low side port is the one that gets cold when the compressor is running.

I cannot differentiate between the low pressure and high pressure


This is a little A/C 101. Follow the A/C lines. All A/C systems have a high pressure side and a low pressure side. The high pressure side is from the compressor to the condenser coil on the front of the vehicle to the evaporator coil in the dash. At the expansion valve in the evaporator the pressure drops. At the expansion valve the refrigerant changes from a liquid to a gas. This provides the cooling. The low pressure side is from the evaporator back to the compressor. Usually the high pressure lines are smaller than the low pressure (suction) lines.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

Looking for low pressure port for servicing Freon in A/C system for 1998 Chevrolet Suburban. There are 2 ports on top of compressor. Which is the low side and which is the high side?


The ports on my 2005 silverado are on the same line,which is very confusing but, in between the two ports is the metering device (orifice) which changes the high pressure gas into a low pressure gas.The two ports are of a different size,with the low pressure being the smaller of the two. You can put your hand on the line, on each side of the metering device connection and the high side will be hot and the low side will be cold
