SHE MADE ME DO THIS TO THE CABOVER..... 

Non return valve on your primary air tank allowing air to bleed down back through the compressor.

“Grab it by the tip” 😂

Get a garden sprayer and mix up some soapy water. Spray down ALL the air lines, brake pods, valves, and any other air-related components. The bubbles spot the leaks. Lots quicker than a hand sprayer! This also works on A/C lines as long as the lines are not too hot. Watch for A/C leaks where the rubber hose is crimped onto the steel or aluminum hard line. If you fill the system and let things cool off for a few hours, spray the soapy water on the A/C lines and connections. Really soak the compressor, making sure to emphasize the fittings, the high pressure pop off, and the compressor input seal. Also keep in mind that you cannot compress a liquid, and when you are adding 'freon' with the can upside down, the liquid you see in the sight gauge on your service gauges is going right into the low pressure side of the compressor, ready to be compressed by the pistons in the compressor. If enough liquid enters the compressor's cylinders, it will hydrolock and often destroy the compressor. Either be very cautious and just trickle the liquid in, or hold the can upright and feed the compressor gaseous 'freon'. In a hurry, immerse the upright can in hot water, or hold the can in the air stream of the hot air leaving the radiator fan.

To the guy that said change the orifice tube. It doesn't have an orifice tube if it has an expansion valve as this does. The valve Bruce called an h block is the expansion valve. If you rev it up and the low side pulls a vacuum the expansion valve is plugged.

Amber, don't be afraid of any camera. I'm 74 years old and I know pretty when I see it. You Rock girl‼️❗😂🤘✌️🖖👍🇺🇸🇺🇸🇺🇸🇺🇸🇺🇸

You're a lucky man Bruce. Amber both a good woman and a good looking woman

Across the expansion valve the pressure drops causing the fluid (liquid) to evaporate in the evaporator. When that happens the latent heat of vaporization (energy required to go from liquid to gas) absorbs a lot of heat (making it cold). AC, heat pumps, and the like really only move heat (pump it) to where you want/dont want it. Very efficient.

Freaking amber know what a bass hole is!!, this beautiful woman always seams to amaze me, she’s always willing and helping with a smile, she’s a very special one keep her close! Iv very glad you two are together the best videos are always when it’s the both of you together, thanks as always for taking the time to share your day’s and memory’s with all of us!

I like this guy he doesn't give up he just just keeps on trying to figure things out.

Shes so cute, her shyness makes her even cuter

Great job Bruce glad to see you repairing the problems on Blue Collar, like the idea of a repair list.

Amber you go girl. Glad to see you 😀😀😀.

Tell her she looks good just like she is with or without makeup she's very beautiful

Who thinks Amber & Austin should have there own channel? That seems to be now what the best content is on this channel. It may have started out with Bruce and the Flatty/Cabover.... But now Austin's work & Amber's personality seem to be the best parts of your videos Bruce! Lets let Amber turn the camera on you for an episode and see how it goes!

Amber, you're a good looking girl. You've got nothing to be ashamed of. On another note, I thoroughly enjoyed the video of the drive you guys did to the logging site. I love watching a beautiful sunrise like that. 👌

Txv= thermal expansion valve. Controls the amount of refrigerant to evaporator. Amber looks good with or without makeup. Great content btw.

Bruce and that got dang click baiting us with amber!

Bruce Tares the dash apart an says “ he kinda got in a rush an frustrated “ Bruce get in a rush ?!! Or frustrated?!! No way !! 😁😁😆

I did a 500 mile turn in 1981 with a White Western Star, mid July with no a/c, I sympathize with you on the Air, glad you got it fixed!! Trucker Mike

Bruce tell Amber she is a awesome looking shella and she don't need make up to look great, You are a lucky bloke to have a great caring person like her bro... CHEERS from downunder !!!

Put the can in hot water when filling. You can smoke a compressor turning it upside down. Just FYI. Also I would change the Orifice tube and spray all connections with soapy water to find a leak on ac and air.

Amber word of warning don't stand still to long, otherwise you'll end up with chrome bits and a set of mud flaps!

You did really good amber, ive tried doing that with ramps and i could never raise them. Like bruce said you always look great on video you have that video personality about you. Keep up the good work you 2 y'all are great

1” cow matt makes the best mudflaps. hangs straight,doesnt curl and doesnt need tacky antisail plates. cut slots into the bolt holes so they dont rip if you catch them. just reinstall. check fanhub for airleak.

Well done, and tell your lady she is good looking for a camera girl,no no she is great on camera

Never supposed to use compressed air in air conditioner... only nitrogen

Love the sound of that!!! Horn trick was awesome!! Sorry Amber. I’m sure it was an accident 🤣🤣🤣🤣

Soon as I was paroled from my COE sentence and on conventional probation in i985 I never went back. Can’t see anything out of those shakers windshields. Hey I get nostalgia. I wish you all the luck.

Grab the tip of it 🤣😂🤣😂😂

I can remember my first Tractor. It's called a catwalk. And yes you need one.

Dang amber looking good and beautiful as usual and congrats Bruce on your cdl and blue collar that is one beautiful truck and keep it up with the awesome content

Yall are awesome. Looks like you have fun everyday man love it!

God Damn I Hate that buzzer in that truck!!! It really hurts every time when it screams in my ear through my handsfree 😖

Prettier without makeup. Always bugs me when ladies feel like they have to cover up their natural beauty.

If you still have the torn mud flaps you can trim them and put them back on. I asked a CHP inspector once and he said that as long as the mudflap is as low as the lowest part of the rim, you’re in compliance. So I figure if that’s legal in Cali. It’s gotta be good everywhere else.

Good vid thanks always good to watch while winding down at a truck stop before going to bed.

Life of an Owner Operator. When you're not driving them you're working on them.

"We evacuated the freon in a uhm, uh....... a safe manner"

14:07 you scared pretty well Amber😂👍👍

Where you hook up the hose high or low side I can’t remember it looks like a wheel air spicket or stem some people call it different, well the spring looses tension and surprisingly they leak from there

Good luck on your test. Amber is a beautiful woman. You are a very lucky man.

Amber you Rock!!!

The truck is looking awesome bruce. Love that colour you went with!

Good luck on your CDL Bruce . Thanks for your awesome content on your channel

He loves going to the chrome shop

Am I weird or does Amber look better without make up?

TXV-Thermostatic expansion valve. It is a valve that senses the temperature of the refrigerant going into the evaporator. If the temp is too high it opens admitting more refrigerant and if the temp is too low it closes and reduces the amount refrigerant going to the evaporator. Most automotive systems use an orifice tube to accomplish the same function. Its primary function is ensure all of the refrigerant going into the evaporator is converted to vapor before reaching the compressor, liquid refrigerant reaching the compressor will destroy it.

Cool video! Amber looks great!..No make up needed.

Soap and water in a spray bottle. To find an air leak.

You're going to Asia CDL you're going to do everything just fine sit relaxed do the test don't tense up just just relax dude don't don't tense up or nothing man just relax when you do everything and you'll pass it man trust me I do the same thing okay just take your time he'll do everything just fine brother amen God bless you have fun

Another problem that will cause high pressure on the high side would be lack of air flow over the condenser, restricted filter/drier, or "non condensable gas" (air) in the system. Good fix! That H block contains a TXV (thermal expansion valve) on the end with the diaphragm. I've done A/C and electrical for just over 50 years, and am glad to see someone who can actually trouble shoot a system to get it running!

Keep doing your thing brother. Nothing but positive vibes .

we thought you sold that trailer and got a 53 foot drop deck spread axle

On a semi the tag needs to be on the front of the truck.

@Bruce Wilson Bruce, if you are having trouble finding a Freon leak, run a lit Propane Torch along the lines. Close enough, but don't burn anything up. When the Propane flame finds any Freon, the flame will turn a bright green. This is how we found difficult to find leaks before Leak Detector was invented. Oh, and that's not an H Block. It's an Expansion Valve. Probably a MEI #1611. A New one shouldn't run much over $50.00.

You're right, she's always pretty! Don't need no makeup! I think it's great that you're teaching her how to to do things properly. She CAN do it!

Your girlfriend is drop dead gorgeous without makeup on let her know she does not need to be shy

Amber your beautiful! Welcome bruce

You two are awesome together! 👊😬👍

Looks like one of the trucks Werner got to haul pillars and long steel beams to Vegas back in 88-89. Always wanted one but never saw them again after leaving the Co. nice truck.

Let her know that a beautiful woman does not need makeup to look beautiful

lol Amber's cute AF without makeup

Love your passion

Good luck on the CDL thanks for the videos👍👍

Amber looks beautiful and she doesn’t need to be ashamed to show her face

That part is called an Expansion Valve.. in 15 years I can't say I've ever heard it called an 'H block'

Your high side pressure will get up to 350 like that, but the engine fan is suppose to kick on and bring the head pressure down. Find out why the engine fan isn’t engaging. More than likely the safety valve is popping in the a/c compressor and purging out all your refrigerant

Hell yeah that's a beautiful truck!

Since when did this turn into the amber appreciation club? The creepy comments are cringe worthy.

She has to learn early, "USE YO KNEES GIRL"!

Bruce, you have done a lot of hard work. That truck is beautiful! Amber is just like my wife......very self conscious.

😂😂😂😂😂amber is nuts 👍🏼👍🏼👍🏼👍🏼😂

No one: Literally no one: Me Bruce and every guy that likes a hot thick and pretty woman: ooo amber pretty hot and thick 👁👄👁

She's hot without makeup

Excellent work and thanks for the awesome content

That H block has a thermal expansion valve made in it and when it gets stopped up you will have high pressure on the high side. You're supposed to replace it anytime compressor goes bad.

@ 12:53 Who the hell cares about makeup!!!

12:13 fart

Lol at you being all organized using a whiteboard with lists.. good for you

When these AC systems get old it's sometimes hard to keep them from leaking down as time hole system is getting were out

Tell her I said that she looks just fine without makeup. Makeup is overrated anyway

girl that sweet shouldn't have to lift those heavy ramps

Save yourself some a/c trouble in the future. Any time you have a compressor go down . Remove the compressor and drier/ accumulator . In a old system its good to go ahead an remove the TXV valve, if it a system that has a orifice tube remove it also. Then properly A/C flush the whole system left, with A/C flush, then install replacement components removed, add proper amount of oil . Then vaccum for at least a hour or longer depending on the cfm. rating on your vacuum pump this will remove all the moisture and A/C flush. Most of the time I will shut the gauge set off and vacuum pump let it set for 30 minutes then check to see if the vacuum has held to make sure there's no leaks that wont empty out the charge in a few weeks. Recharge an you will have a problem free A/C unit if all components are good for several years to come.

Good luck with the a.c. system my dads freight Shaker was bad about needing charged once a month or soo

Tell her for me she’s very pretty.

Yes nice find and also make sure you change g out the filters.

As far as the mud flaps you need to cut them down so they don't drag the ground and if you are going to keep doing hauling in the swamp you might want to cut them down to where they are about 6 to 8 inches from the ground with the truck aired up

Thats cool that I'm watching someone who's pretty popular on RU-vid with 438k subscribers and is literally one town over. I'm from Land O' Lakes, FL. Keep up the good videos Bruce!

Did you replace the receiver dryer on the A/C?...Always a good idea to replace whenever you open the system..

Hey remember during driving test some instructors will watch to make sure you double clutch and will fail you if you don't. Others just don't care if you float or not, also on the AC if you have further issues you also have sleeper components that can clog up. Some freightliners newer than 94 have condenser for the sleeper that tends to plug up and mess up the whole thing.

Check your air bags for leaks. After they get old they tend to leak. Bottle with soap water works good for finding air leaks. Great video thanks for sharing.

Great video and good luck on your CDL test

Amber ... please don't be shy .. we are here is why we are you fan .. you work hard like all and you have nice smile .. cheers

Can’t wait to see you in Indiana!

you & Amber's shenanigans are adorable- my wife is the exact same way

U guys was making me laugh so hard this morning... Gud video n tell amber she is very pretty u r a blessed man.. I lost mine last year. She passed away.Make every day as if it was ur last! Cuz I knw this might sound corney but life is never garanteed!!

You'll like that AC when doing some of the longer trips in particular. BTW the music you guys have for a lot of your stuff is very good ;-)

It’s normal for no air. When I was going for my CDL all the yard trucks had no air. So we as students had to build up air pressure in the system. I hope that this helps you.

14:29 14:30 “Your an asshole” thanks for the laughter

Dude has Aaron washing semi trucks and Amber doing trailer ramp-duty. For some reason, all I got out of this was Bruce doing that diabolical Joker laugh while wearing Macho Man Savage Gargoyle sunglasses.... 😂
