This is actually a trick question. There is NO High Pressure Port on the Volvo 850 Turbo. Service is done by connecting to the Low Pressure Side and using this access to both Evacuate and Service. Chrysler for a few years did not use a High Pressure Port and required connecting a Scan Tool to the OBDII Connector and taking readings this way but Volvo does not even offer this option. Todd
Hello, while I was searching my Volvo air intake I found out my required Part at AutoSparePartsUsa.com. I would like to suggest you this link ,check it out:http://www.autosparepartsusa.com/Getsubcatsearch.aspx?modelid=846&catid=240497&catname=Air~Intake
remove the air filter assembly and the low pressure and high pressure service ports and right there with caps on them.
Yes. there is a low and high pressure cutoff switch for the newer cars 1995+
The 1996 850 doesn't have a high pressure port. Recharging is done through to low pressure side.
relieve the pressure off the high pressure side
you should have 2pumps, a low pressure in the tnk and a high pressure in the line.
It don't have a low pressure valve. the high pressuer sensor is in the high pressure line next to the raditor. It don't have a low pressure valve. the high pressuer sensor is in the high pressure line next to the raditor.
it is the low pressure side
non condensebles in system dirty cond coil high ambient poss over charge
under the hood on the passenger side toward the frount of the car. With the engine off look just below the windshield washer filler neck and there will be a hex shaped cap, thats it, remove and this is your low side port. Volvo 850's dont have a high side port.
Recharging should be on low-pressure side only
high head pressure and a higher supply temp.
you will only find a hi pressure side
remove the air filter assembly and the low pressure and high pressure service ports are there with caps on them.
The low-pressure fitting is on the side of the accumulator, at the back left corner of the engine compartment. (Standing in front of the truck, looking towards the back.) The high pressure is just below and in front of the accumulator. Generally speaking, on all cars the low side will have larger diameter pipes than the high side. The fittings on modern cars (running 134a) are slightly different sizes, which makes connecting to the wrong one virtually impossible.
Most high pressure lines have a red cap on them, and they are usually smaller in diameter. It runs from the condenser to the TX valve/Evaporator.
Not sure what your asking yes you charge from the low pressure port it is the smaller one your hose should not fit on the high pressure side
The high side will not hook up to the hose
The best way is always to use both high and low pressure. But you can do with only one
There is a low pressure fuel pump in the gas tank, and a high pressure in-line fuel pump located on the under-carriage beneath the drivers seat
The low pressure port (Suction) and the high pressure port (Discharge) are both located on the back side of the compressor.
You have a leak; most likely in the high pressure side of the system.
What you're describing sounds suspiciously like a worn compressor.
