1997 Nissan Pathfinder Q&A

1997 Nissan Pathfinder Question: How to charge AC in pathfinder

looking from the front of my pathfinder whitch port do i connect too in order to charge my AC with a can of 134 refrigerant? -
Answer 1
You need to connect to the low side port. The low side of the a/c system will be located on the a/c pipe that goes from the a/c condenser to the a/c evaporator. Sometimes it will be on the a/c accumulator, but it can be anywhere between the accumulator and the evaporator. -

Ok... where is the A/C condenser and A/C Evaporator... ....or where is the Low side port located on a 1997 Nissan Pathfinder? -

look on the left side under the hood, as you are standing in front of the vehicle, the lines are running from the firewall, the cap is gray with a L on the top. you will have to buy a 134a hose and fitting to put in the 134a in to your a/c unit. -
Answer 2
you charge the unit from the low side, not the high side. they are marked on the plastic caps. you can buy a charge line and 134a in any auto parts store. if it is just low, you may need a half of a can to a can. this unit only holes 1 1/2 lbs. of 134a!!! if this does not make it blow cold you have other problems, do not keep putting in 134a! you will have more problems!!!! -
