Vehicle AC System Diagnosis for Beginners. A/C System Troubleshooting
Vehicle AC System Diagnosis for Beginners. A/C System Troubleshooting
In this video I'm going to show you the steps that you can take to diagnose an AC system that does not blow cold. The first thing you you should verify is, does the compressor turn on. If the A/C compressor does not turn on, then the vehicle is never going to get cold. There are multiple things that could keep a compressor from turning on: no refrigerant, electrical problems, or a mechanical problem with the clutch.
If your clutch engages I will also show you how to diagnose problems with your AC system using a manifold gauge set. I will show you the correct way to connect manifold gauge set to your vehicle. Once the gau...

    Great instruction from you as usual, but in my case I got an old 2002 Nissan Pathfinder, and I noticed the springs are thick and strong looking. But my main concern it's got almost 200,000 miles on it. So I figure the springs are probably getting weak, so I'll just buy two complete strut assemblys from Monroe. 😇

    Waxoyl hardcoat is a one and done deal. You spray it on and it cures but it doesn’t fully dry. It’s designed to stay flexible but seal out the moisture. You just look it over once a year and add more to areas it thins out in. Rovers North America recommends it for restored land rovers which have an aluminum body but use a heavy gauge steel frame. I plan to do the underside of my 2022 Tacoma this fall before I buy out the lease. Sure I’ll cavity wax the inside of the doors but it really does best in the tailgate corners where Tacoma bodies tend to have their worst rust. Sprayed into crossmembers and boxed sections is where you’ll find it does best. Done correctly it gives your frame that gloss black new appearance and it’s unaffected by UV light or high pressure carwashes. End result? Your car will last long enough to get payed off and give you years of enjoyment with no car payment

    To further emphasize how AC works, the main principle to consider is that HEAT = ENERGY, basic physics state that “You cannot create nor destroy energy”, you can either transform or transfer energy; therefore in an A/C system (in accordance to thermodynamics) you cannot make it “cold”, the A/C system is either transforming or transferring “energy” (heat) from or to the cabin whenever you set the temperature to “cold” or “hot”.

    Orifice tube systems don't have a receiver/dryer. They have an accumulator. They are not the same thing. Additionally, you want to burp the blue hose at the manifold end after opening the can in order to purge the atmospheric air out of the hose. Do this by a quick twist of the fitting--all you need is a quarter-second pulse.

    I've used the STP in a 4 cylinder Ford Ecosport. No turbo. Had a slight miss before at idle. After it idled great. About half way through the cleaning I did start to get a smoke cloud and at the end I had a large smoke cloud in the driveway. About 600 miles later both O2 sensors had to be replaced for slow switching. This was about 30,000 miles ago, same cat on the car still. No issues. Oh, I did manage to get the STP for $32 using my works wholesale account at the parts store.

  • @TS-qd2uj
    @TS-qd2uj 2 дня назад

    0:00 Thanks for a very well explained tutorial, with excellent pointers! Just one thing mentioned by another follower to remember: If you are working on a system that still has refrigerant in it and you do not have a vacuum pump, you still need to purge the blue low pressure line and the red high pressure line besides the obvious yellow hose, before testing the system (for pressures with the gauges). You can do that after hooking up the lines to your car's A/C system per Repair Geek's instructions by very quickly backing off and hand re-tightening the fitting of each hooked up line on the side of the manifold which holds the gauges. You will loose a very small amount of refrigerant from your car's system, but you will ensure the blue and red hoses are free of air and moisture. Otherwise a vacuum pump shoud be used as shown by Repair Geek. Thanks to John!

  • @John-dp3ln
    @John-dp3ln 2 дня назад

    Vac pump not needed before connecting hoses, leave fittings a little loose on gage set, connect to car, let system pressure purge out air, just a little, doesn’t take much. Otherwise excellent.

    • @TS-qd2uj
      @TS-qd2uj 2 дня назад

      Thanks for confirming. For two days now, doing homework on RUclips on how to properly purge the air out of the low and high pressure hose on a a/c system that still has some 134a in it, I only found one besides your note explaining how to simply purge air out of the Blue and Red hose. Everybody talks about clearing the yellow hose with a squirt from the can, but no one seems to mention the other important hoses. Thank you for confirming. Of all the videos out there, Repair Geek is doing a fine job explaining otherwise. I'm glad I watched it.

I was gonna just prime and paint with Rustoleum oil based products, then coat with fluid film. Now that i see this, should i just direct coat with dyed fluid film and omit any paint/coatings altogether??
