Rich: Thanks for the video, man. It really helps. Very easy to understand the basics and thanks for the additional Ambient Temp vs System Press…a life and wallet saver.
Hey rich you did not mention should the knobs be turned back on or do they stay off during the reading of the gauges??or did i miss you mentioning to open them up in the video? or does it read the pressure with them closed??thanks please let me know…J p. s. sorry for all the questions today but alot of your videos i have similar situations ….
@00Kaporal that is a sign that your orifice tube or expancion v is not working because is clog or your condenser is block the high side pressure goes high to a dangerous reading a reading of 375 psi the hose may blow up touch the outlet of the condensor if it is very hot it is your condensor the problem spray some water over the grill you will see a decrease in pressure but what is important is to notice is the pressure relation between low and high exp:L25 H230 that is a expancion Valve
Is there a manufacturer of these gauge sets that is more highly regaurded …just wondering if you had to replace your set and wanted to upgrade …is there another company you would consider?

Rich, my friend has a 2002 dodge ram 1500. The 2 vents on the drivers side throws cold air, but the 3 vents on the passengers side, throws cool air. The system has proper freon level. I cant find the problem. Please give me any ideas, to find and fix problem. My e-mail address is hectorelizondo88@yahoo.com
@00Kaporal At the present time i do not have enough experience to know the symptoms of a bad expansion valve but i believe on of them is reduced flow which translates into low temps at the vents.
@richpin06a
1st thanks on your quick reply. one of the problems is that when I’m at a stop (idol) the vent temp goes to around 74-80d & at freeway around 60d, I replaced the compressor last month and I had someone else charge it, it cooled good for a few weeks, do you think I should change the exp. valve, (I already bought it algo w/freon)
@00Kaporal Let me start by telling you i still have a lot to learn about air conditioning that being said with readings like 50 on the low and 420 on the high sounds like a over charged system.

I’m new here & I’m hoping to help me out.
I have a 2001 dodge durango, 4×4 5.9l, I was told to change the exp. value.
I hooked up the manifold gauge after 5min the low reads 50psi high at 420psi
at 2000rpm low at 35 & high at 375, temp at vent 66d outside temp 95d.
with this info. does it tell you if any other part needs to be replaced?
thanks for your help..
Rich, thank you for the R134a temperature pressure chart shown @ 5.00 min of your video. I have a car buildt before 1993 which uses R12 refrigerant & which has not been converted to R134a. Do you have a similar tenperature pressure chart for R12 refrigerant ? If you do, would greatly appreciate if you can share it with your viewers.
Thanks.
so I know ur not looking at, but what would u recommend I look at with the high side pressure high and low pressure low? Do you think the 1990 honda has an orifice tube? and last question if it does have orifice is it in the tube near evaporator? sorry if I bug you and thx for ur input

@CHIBA280CRV The gauges always stay closed!

good video i like that you said how to read your gauges

@1octano when you say the outlet, youmean the “electrical outlet”?
thanks for your responce..

@treborterb Sure it is a Mastercool #89660
#9 by treborterb on January 3, 2012 - 4:52 pm
Can you tell me who the manufacturer of the gauge set you are using is and what model it is…thanks.

I wanted to ask if anyone knows, what would make your auto ac alum hose freeze up?

#18 by richpin06a on January 3, 2012 - 9:19 pm
@realjdmek9 Yes… that is the first thing you do before hooking up your gauges is to close the valves.
#19 by realjdmek9 on January 3, 2012 - 10:05 pm
Do you leave the the valves closed on the manifold while checking the pressure???
#20 by opsvideo2008 on January 3, 2012 - 10:11 pm
@richpin06a Thanks for your reply. It is OK. I just found it on the internet posted by a guy who himself found the information many, many years ago.
#21 by richpin06a on January 3, 2012 - 10:14 pm
@opsvideo2008 I do not have a chart for R12 because i have never worked on a car that used it.

@yamaduderory I am not going to be much help to you there because i do not work on Hondas.

#25 by richpin06a on January 4, 2012 - 12:08 am
@audiocable Yes low on refrigerant or a bad expansion valve would be two things to consider.
