Question about 2005 Chevrolet Trailblazer Ext
The one closest to your AC compressor... i.e. the part that the belt spins around.. Is the low side.. Not to mention, air conditioning recharge hoses ONLY FIT on the low side.. Worst case scenario, try both.. the one that it clamps down on to is the low side..

I have a 1998 dodge neon 2.0 L DOHC I have an a/c problem. It is blowing warm air. Before I try to fill it I find the pressure on the system is already in the red zone as in far too high. I have emptied the a/c unit and there was some refridgerant in it. But when I went to fill it up again the gauge immediately ran back up close to the red zone as I was partially emptying the referidgerant back into the system. I have the a/c running when I am doing it? Is that correct? I was told that an orfus tube could be one of the problems as it may be blocked probably by someone putting a sealant from the past? If so I called the dealership and they could only tell me there are 3 tubes and do not know which one I am talking about? Also my car has 2 black caps and no blue cap how do I know where to fill it? I see the hose line only fits on the one valve which is the one on the line and not on the container. Can anyone give me some ideas. Thanks. Gerry firstname.lastname@example.org

Problem is this. Your system is R12 and you are looking for the port for 134a refrigerant. The low side port for the Fiero system for charging is in the front on the accumulator/drier (sliver can).

The AC low pressure service port on the 1998 olds cutless is located next to the firewall behind the left side of the engine.

please try a simple test for me. no.1: remove the radiator cap off the radiator. no.2: if you could see the see the radiator opening from within you car much better, then try to crank your car to an idle. if coolant blows out of the mouth of the radiator like an erupting volacano, then take note of this. no.3: while the engine is running at idle try to look at the coolant through the mouth of the radiator, if you see bubbles like washing your hands with soap and the suds trailing to a drain, then take note of this.
the reason why i'm telling you all of this is that, the coolant should flow like a clear stream. you don't have to worry about purging the system of air because, the water pump is already situated a few inches below the highest water capacity of the radiator. it means that if you drained your system and refiled the radiator to the brim, just start your engine and add a few more coolant to fill it up because the running engine simply purges the waterpump of air.
now, if you tried no.2, and you did see and somewhat like an errupting volcano, that means your engine is in serious trouble, so is no.3. however, a tolerable bubble flow is still possible but your valve clearances should be tuned if this happens. excessive bubbles accompanied by blow out of coolant means your combustion gases are seeping through the head gasket due to a damaged head gasket, warped cyclinder head, cracked cylinder head, or even a cracked cyclinder liner(or bore where the piston glides up and down). think back! did you ever experienced overheating you car to a point where it stalled completely? then, you need a thourough engine checkup.

the smaller cap, is where it is refilled at, that is the low side, the container will only fit on one of the openings, if fluid or air sound happens and doesnt stop for the neck on the ac recharge bottle then you are not on the right spot. but normally the caps are set as black and blue, but look for the smaller cap, if they dont look different before you do anything remove the caps, put the openings on the caps back to back to each other and look close you will see a difference in the cap size... the smaller is where you need to conect the recharger up to... my guess would be the cap by the cylinder is the smaller... I dont know unless I could see it... hope this helps...

If you have a refill kit, the hose will only connect to the low side hose. Most likely, the hose under the filter is the high side hose. Hope this answers your question. Best of luck.
p.s. When recharging AC, have engine running and AC on HIGH

i belive on this year car and make its located under the air filter box, remove the intake hose then the cover for the air filter, remove the filter then remove the lower part of the air box there you will see the filter dryer and the lines coming off the dryer and there will be two fittings to charge the ac system, the smaller fitting is the low side this is the side to charge through, make sure not to overcharge the system and add oil as needed, a good idea is to add dye to the system to help in finding the leak if system goes low again, theres a decal under the hood or on the dryer that tells you how much freon the system can hold. if you under or overcharge the system the air may be cold but future ac damage is for sure, good luck.
