I need the high pressure return line that runs between the condenser and evaporator This is for a 2000 olds Intrigue with 3.5 l engine

well yes you want to replace them all then replace them all,... if its for a leaky line usually the high pressure line is leaking id just do it they are not to prome to leak if done right.so replacing them all just for fun would be expensive and kinda pointless.

Here is a system overview. The low side port is #5 in the picture. Hopw it helps ya.. Cobra

not exactly sure but using info below you can find it.

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer back to the compressor suction.

There will be about a 1" nut on the low pressure line between the firewall and the compressor. Remove nut and on the male side use a pair of kneedle nose pliers and remove orifice tube. Note orientation of tube.

Replace tube, reassemble, evacuate air from system, recharge with freon.

the fixed orfice is located at the high side ac line where it goes into the evaporator core at the firewall. u will most likely need a special tool to get it out without ruining the evaporator intlet

4. Remove the six bolts and the two radiator upper support brackets.
5. Remove the upper radiator hose.
6. Remove the bolt and position the receiver drier aside.
7. Disconnect the dual flow coolant valve electrical connector and the A/C line from the fan shroud.
8. 3.0L engines only:
   Disconnect the Throttle Position (TP) sensor and the Idle Air Control (IAC) valve electrical connectors.
9. Remove the bolts.
10. Remove the bracket.
11. 3.9L engines only:

6. Replace the following
   The upper radiator sight shield. The air cleaner outlet tube. The six bolts and the two radiator upper support brackets. The upper radiator hose. The bolt and position the receiver drier aside.

Hope help with this (remember rated and comment this).

Well not sure and wouldnt swear on it but iam sure that you do not have enough gas by weight.The gas has to be weighed in when refilling.Also remove the restrictor valve because it could have bits from the old compressor blocking the venturi.Also the high pressure side should read a least 20bar 14.7lbs =1 bar ---20 bar= 294lbs

the tracer is the same as the ESCORT, right?? TRY THIS--I WORK ON PLENTY OF ESCORTS--LOOK UNDER THE AIR CLEANER/CONE ASSEMBLY--THERE WILL BE A BLACK METAL BOX(FULL OF RELAYS) ONE OF WHICH IS THE A/C RELAY--TRY TAPPING ON IT WITH A LONG SCREWDRIVER OR SOMETHING SIMILAR WHILE U HAVE THE A/C ON. IF THE A/C SUDDENLY STARTS WORKING U NEED TO GET A NEW RELAY BOX(I THINK ITS CALLED A GEM MODULE) i do have a question- does the blower motor work?? how do u know the compressor is good??do you have 12 volts going to it??? this relay box is pretty common to go bad--u have to remove the air cleaner in order to get to it.get back to me.

U SHOULD NEVER HAVE TO RECHARGE, IF YOU DO U HAVE A LEAK AND THAT NEEDS TO BE REPAIRED 1ST BEFORE A RECHARGE, THE SERVICE RECHARGE PORT IS ON THE INSIDE OF THE OF THE PASSENGER FRONT FENDER, U MUST GET AT IT FROM UNDER THE CAR, IT IS ON THE ACCUMULATOR AND NOT VISIABLE, U MUST FELL IT, VERY HARD TO GET AT, GO TO LINK BELOW FOR PICTURE

Basic AC system consists of Compressor pump (on engine), Condenser (front grill with radiator) and Evaporator (Firewall). Pump has two ports output (high pressure) and return (low pressure). Follow lines from pump. High side is usually between pump and condenser. Follow lines and find second port this will be low side (refill) port. Paint or replace port caps (red high, blue low). Also, refrigerant in system determines port size (R12 or R34).

somewhere in the coolant line from the condenser, front of car, to the evaporator, in the air box. I have a 2000 sunfire, so there is a line nut right at the evap inlet, very easy to to, I'm not sure exactly how they were set up in 92', that would have been an r-12 sytem. Still it would be along the high-pressure liquid line flowing from the condenser to the evaporator, it bassically drops the pressure of the coolant to make it colder thus cooling your interior. hope this helps
