Question about 2005 Lexus GX470

1 Answer

I have a 2004 lexus which is short on freon. I just bought the latest refrigerant and a pressure guage. I am not sure if this refrigerant is compatible and where the low pressure port is. There is a clear window with a port with a cap that says H (i assume Hight) in the front left of the radiator (facing it). Where is the low pressure port and what refrigerant do I need?

    Hi, is it in view or do you have to take the engine cover off of it?

  • rjslamalaw Mar 27, 2011

    I can't see anything along the right side which has the battery and the fuse box with a cover over it. In the Front there is an "h" with a clear window with a spot to put what looks like a tester of some kind which appears to come from the condenser.

    Can you help direct me or show me a picture of where it is.

    I am sending you a separate email with a photo of my car.

    Please advise.

2004 sebring air conditioner stops and starts


Low freon will cause the compressor to short cycle, when the compressor runs the pressure in the low line is pulled down and the low pressure switch turns it off. Not running the pressure builds up and turns it back on. In the old days there was no low pressure switch, with no freon to carry the oil the compressor was destroyed.

My lexus es300 2003 a/c light keep flashing


The problem may be low Freon, has it been pressure tested to see what the system pressures are? If not sure try adding some freon yourself using a a/c recharge kit available at most autoparts stores, just follow the instructions, if you are sure freon pressure is ok there may be a problem with the a/c clutch relay, it's located in the fuse box under the hood, all relays and fuses are marked on the inside of the cover, look for the 'MG/CL relay and try replacing it. Other than that there's not much more you can do yourself and it will require a professional using some specific special equipment to check the system.

How to put in freon


First buy one of the Auto Pro Refrigerant units with coolant and guage together at an Auto Parts store. you must locate the" input valve on the cooling line..should have a nipple on it,that screws off . There are 2 but product and guage only fits one. Unscrew can from guage and remove safety tab.....RE_screw can back on too gage making sure it is tight enough to puncture can. 4 clocklike hands on guage,,set the smallest arrow to approximate outside air temp. Push end of refrigerant hookup connector onto imput "nipple".. start car,,turn A/C on max cool............pull trigger on refrigerent unit,,,,shake and roll can slightly...when you release trigger,the gauge will indicate how much you have charged it...if completly empty,it will take about one half can,before compressor cluch begins to turn...squeeze release....squeeze,,release until pressure had indicate charged.

It's the tire pressure monitor. Inflate your tires to the proper pressure.

I bought a bottle of freon and a guage with an attachement that is supposed to fit onto the lower valve, but it does not fit. Why?


try the other fitting. it is not the lower fitting, but the low pressure line of your a/c that your looking for.

My 2004 ES330 A/C isn't cooling enough. I took it to a technician for checkup and he said everything is fine and there are no leaks, what might be the problem? if it needs recharge, what kind of...


R134 freon.

you need to put manifold gauges on the system to check pressures.if it is full of freon the low side should be around 30 psi and high side should be around 175 psi. if pressures are ok or alittle low on the low side you need to check exspantion valve. common with the es300's

A/C went out on a 1999 Chevy Cavalier


What do you mean by went out,if it just one day stopped working,it could just be low on freon.does the a/c compressor come on? to find out....start engine..turn a/c completely off....turn on a/c....as soon as you turn on a/c you should hear a click sound under the hood,if you dont hear click,you may just be a little low on freon.you can add freon yourself instead of paying alot at a shop.buy some r134 refrigerant,walmart sells several differnt brands just make sure it comes with a hose to add with.find your a/c low pressure line on car.....connect hose attached to refrigerant bottle...snap onto fitting on low pressure on a/c line.....start car with ac on add refrigerant......soon you should here a click....if so that was the compressor coming on,add freon until guage on bottle is in the safe zone. Ihopoe this helps you,if it doesnt you may need to take it to a shop.

How do i put freon to a 1996 dodge stratus


Most auto parts stores and hardware stores have kits to refill your system. The instructions will show and tell you where and how to connect it. I would strongly suggest you get one with a gauge to make sure you don’t over fill. And a kit that includes the oil.
