About this episode

Shop culture can turn toxic fast, and the people doing the work often get undervalued. Greg Hilliard walks through his path into heavy-duty diesel work at a Ford dealer, then zooms out on dealership politics, diagnostic reality, and how “an hour of diag” isn’t always an hour. He criticizes opaque labor-rate math, bottlenecks, and pay structures that punish techs. Digital video inspections and AI could shift trust toward technicians, while staffing shortages and mental health remain urgent.

Technical Too Afraid to Ask
Term

EGR valves

"We had a great crew of guys on our shift. Man, we could punch out the work. We were changing like we do two EGR valves of, on Volvo D14s a day. Like we were rear cover jobs, clutch jobs like."

An EGR valve is part of a truck’s emissions system. It helps the engine burn cleaner by reusing some exhaust gases, and if it fails, the engine may run poorly or fail emissions checks.

Term

safety

"So we don't know what it's going to take to get through a safety. So I can't tell you what we can drop to."

“Safety” here means the truck has to pass an inspection so it’s legal and safe to drive. The dealer hadn’t checked it yet, so they didn’t know what it would take to pass.

Car

Ford F150S

"...ry, very busy dealerships like these guys. 4 to 6 F150s a day left this place with, you know, new, new F1..."

The Ford F-150 is a large pickup truck made for hauling and towing. Because so many people drive them, repair shops see them a lot. That’s why it often shows up in stories about busy dealerships and frequent service.

Car

Honda Civic

"So, so I'm doing, you know, Honda Civic clutch jobs transmission on my belly and jamming them in."

The Honda Civic is a very common car. The host is saying they used to work on clutches and transmissions on Civics, which are jobs that can take real time.

Term

service writer

"we had a service writer who felt like he should be the service manager. So he was, I feel like he was undermining the service manager."

At a dealership, a service writer is the person who takes your car’s information, writes the repair paperwork, and communicates between you and the mechanic. The host is saying that role can sometimes focus on the wrong things.

Car

Volkswagen Bus

"...nience to them that they have to take the shuttle bus back home or something like that. The service man..."

The Volkswagen Bus is a van that’s designed to carry passengers. If it’s in the shop, the owner may need a ride or shuttle while repairs are happening. That’s why it can show up in stories about service logistics.

Term

service manager

"The service manager is the one that's looking at the whole operating cost of the whole department."

The service manager is in charge of the dealership’s repair department. They’re responsible for how the shop runs overall, not just individual customer interactions.

Car

super duty power strokes

"So you, you got to the Ford dealer. How was that a transition from what you'd been doing, like in the, in the equipment side of things and I to just going to. Working on super duty power strokes."

The host is talking about Ford’s heavy-duty trucks (“Super Duty”) with diesel engines (“Power Stroke”). They’re saying the repairs can be more difficult because the engine bay layout makes certain jobs harder.

Term

alternator

"You flip the hood open and there's the alternator. Right? Yeah. Super duty truck with a 6 4. The alternator ain't there."

The alternator is the part that keeps the battery charged while the engine is running. The host is saying it’s annoying to replace on certain trucks because it’s hard to reach.

Person

John Mills

"I had a great mentor there. John Mills. He'd been with the company like 25 years."

John Mills is the experienced coworker who mentored the host. The host says John taught him the right steps for tough repairs so he could learn faster.

Car

Chevrolet Spin

"Okay. You'll spin the thing if you did it John's way. He had the se..."

The Chevrolet Spin is a small van-like vehicle meant to carry people. When someone says “spin the thing,” they usually mean operating a part or checking how the car responds. In a repair setting, that kind of comment often relates to how the vehicle drives or shifts.

Term

DPF delete

"I think that cab was off three times before it was finally right. The sales guys, you know, the sales guy said he's got to take a mortgage out to pay the freaking service bill after that. But you learn like I've got a policy on. On those super duties. Is Anything I did, for the most part, anything I disconnect is hard to get at."

DPF delete means removing or bypassing a filter that traps soot in diesel exhaust. The host is saying that when a truck has been modified this way, it can come back later with other problems and extra work.

Term

check engine light

"We bent a pin putting the. Putting the harness back on the back on the ecm. So I got this phantom check engine light like that truck that."

The check engine light comes on when the car’s computer finds a problem. Here, the host says it came on even though the underlying issue was caused by a wiring connection mistake.

Car

Rolls-Royce Phantom

"...arness back on the back on the ecm. So I got this phantom check engine light like that truck that. That was..."

The Rolls-Royce Phantom is a very expensive luxury car. If the check engine light comes on, it means the car’s computer has detected a problem. Fixing it can involve checking the engine computer and related sensors.

Term

ECM

"We bent a pin putting the. Putting the harness back on the back on the ecm. So I got this phantom check engine light like that truck that."

ECM is the engine computer. If a connector pin is damaged or mis-seated, the computer can think something is wrong and trigger warning lights.

Term

serpentine belt

"Is Anything I did, for the most part, anything I disconnect is hard to get at. You're getting a new one, you're getting a new fan belt or new serpentine belt because it's right here."

A serpentine belt is a belt that powers several engine accessories. The host is saying that when they have to take things apart, they’ll also replace easy wear items like that belt to avoid coming back later.

Term

screw compressors

"We're talking screw compressors, style supercharger. [1321.0s] So service that stuff for a while."

A screw compressor is a machine that makes compressed air for industrial use. Instead of pumping air in cycles, it compresses air continuously, which is why factories like them.

Term

supercharger

"We're talking screw compressors, style supercharger. [1321.0s] So service that stuff for a while."

A supercharger is a device that forces extra air into an engine so it can make more power. Here, the speaker is using the word as a comparison for how the system increases pressure/airflow.

Term

diagnostic

"As we were just having this conversation before I got on, you know, initial diag used to be like, you walked out and you hit it with a hammer, and it smoothed out and started to work again. Your diag was done."

Diagnostic work is how a technician figures out what’s actually causing a problem in a car or system. The point is that modern problems often need more steps and checking than just quick fixes.

Term

tsbs

"You're scanning, you're checking for tsbs, you're checking identifix, you're checking Google, you're talking to a friend. You're doing whatever. That's just the first hour."

TSBs are official notes from the car maker about common problems and what to do to fix them. Instead of trying random repairs, a technician can look up the right procedure.

Term

identifix

"You're scanning, you're checking for tsbs, you're checking identifix, you're checking Google, you're talking to a friend. You're doing whatever. That's just the first hour."

Identifix is a diagnostic information service used by technicians to help narrow down causes based on symptoms, codes, and repair history. It’s part of the modern “evidence gathering” workflow the speaker argues takes longer than a simple fixed “hour of diag.”

Term

hour of diag

"And now everybody's like, but I told the customer, you know, they've got an hour of diag. Well, an hour of diag is an hour diag doesn't mean an hour."

“Hour of diag” is when a shop charges for diagnostic work by the hour. The speaker argues that today’s troubleshooting can take longer because you have to test and confirm the real cause.

Term

labor rate

"a couple things, tools that we as techs need to have is you need to know what your shop labor rate is. And a lot of techs don't know that."

“Labor rate” is what the shop charges per hour for the technician’s work. It’s one of the biggest drivers of what the final repair bill costs.

Term

door rate

"And, and 80%, you know, 80% of 2200 hours a year is a lot of freaking money. Right? Yeah. At the door rate."

“Door rate” is the shop’s hourly price for labor—the rate they charge customers for technician time. It’s the number that helps you estimate what a repair might cost.

Term

bay efficiency

"Most of the shops I were at, of course, tracking our bay efficiency. And my, our target was always 75 to 80% because you, because you take two breaks a day, we're gonna have some admin time."

“Bay efficiency” is how busy and productive the repair work area (the bay) is. It’s basically a measure of how much real work gets done versus time lost to breaks or delays.

Term

30 to 100% margin

"So you go, okay, If I build $250,000, and that doesn't count a single part that I put on at a 30 to 100% margin."

“Margin” here means the extra profit the shop adds when it sells parts. It’s different from the technician’s labor—parts can be marked up a lot even if labor is unchanged.

Term

brake caliper

"I've got a, I've got an invoice here from a shop in Gainesville, Florida. They charge $1579 to put a brake caliper on a pickup truck. You can't justify that."

A “brake caliper” is the part that squeezes the brake pads to stop the car. Replacing one usually means swapping the old unit for a new one and making sure the brakes work correctly afterward.

Place

Gainesville, Florida

"I've got a, I've got an invoice here from a shop in Gainesville, Florida. They charge $1579 to put a brake caliper on a pickup truck."

Gainesville, Florida is the city where the example repair shop invoice came from. It’s mentioned to support the speaker’s point about overpriced work.

Term

PDI

"They had to send their cars to a sister dealership to get BDI'd, you know, license plate on. Yeah, like"

“PDI” usually means a “pre-delivery inspection,” where a shop checks a vehicle before handing it to the buyer. It’s like a final checklist to make sure everything is ready.

“Mileage” is how many miles (or kilometers) the car has been driven. The speaker is saying the shop needs that info when writing up the repair.

Term

oil change sticker

"I don't think a technician should be filling out an oil change sticker. One we got greasy fingers and terrible penmanship... So it's nothing for them to scribble out the oil change sticker, which a pet peeve of mine."

An “oil change sticker” is the reminder label a shop puts on the car telling you when your next oil change is due. The complaint here is that the sticker information is sometimes wrong or missing.

Term

kilometers

"it'll say 58,000 kilometers, like exactly. So you're telling me that car came into the shop at 52,000 on the button, right?"

“Kilometers” is the unit used to measure how far the car has been driven. The speaker is complaining that the maintenance reminder numbers don’t seem to match the car’s actual mileage.

Term

oil grade

"they don't know what grade of oil, what oil to buy when we send them out of there after an oil change."

“Oil grade” is the specific type of engine oil your car needs. The speaker says the shop should tell you which one to buy next time.

Term

air filter margins

"Like, I guess the, the air filter margins aren't very good. Like, let's sell some more oil."

“Air filter margins” means how much profit the shop makes on air filters. The speaker is saying if that profit is small, shops may try to sell other products instead.

Term

dipstick

"This is where the dipstick is. Here's a complimentary rag that we picked up off the floor and threw it in the trunk for."

A “dipstick” is the stick you pull out to check how much oil is in the engine. The speaker is saying shops should show customers where it is and how to use it.

Term

wheel out key

"Like, the oil change, I. It's back to my wheel out key thing, right? Like, advisors should be like, finding wheel out key printing."

“Wheel out key” sounds like the moment the car is ready to leave the shop and the keys are handed back. The point is that the shop should make sure the customer-facing paperwork is done at that step.

Term

DVI

"But you talked about these DVIs, which. One of the things I want to look at in the future is some kind of system where I can interact with my customers virtually like that. Hey, I'm going to walk around your car and you can have a little bit of personality."

DVI here means a video inspection. A technician records what’s wrong with your car and sends you the video plus the estimate, so you can see the problem instead of just hearing about it.

Part

clutch adjustment

"And he would come in, say, my truck needs a clutch adjustment. Is Derek in today? No, he's on afternoons."

A clutch adjustment changes how the clutch engages when you press the pedal. The story is that one technician knew exactly how to set it so the customer liked how it felt.

Term

chat GPT

"You can't tell me that that something like chat GPT if you gave it the credentials to get into your dealership's labor labor tables and parts lookup... it'll start spitting out the part numbers."

The speaker is talking about AI (ChatGPT) that can answer questions and generate lists. Here, the idea is it could help shops quickly put together an estimate by using the right vehicle and parts info.

Term

parts lookup

"You can't tell me that that something like chat GPT if you gave it the credentials to get into your dealership's labor labor tables and parts lookup say chat GPT."

Parts lookup is the process of finding the exact correct part for your specific car. The episode suggests AI could do that searching and listing work quickly.

Term

labor tables

"if you gave it the credentials to get into your dealership's labor labor tables and parts lookup say chat GPT."

Labor tables are time estimates for repairs—how many hours a job should take. Shops use them to figure out what to charge for labor.

Term

VIN

"You can't tell me that that something like chat GPT if you gave it the credentials to get into your dealership's labor labor tables and parts lookup say chat GPT. This is the VIN of my Aerostar van."

VIN is your car’s unique ID number. It’s like a fingerprint for the vehicle, and it can be used to look up the right parts for that exact model.

Part

catalytic converter

"two upper ball joints and a, and a catalytic converter."

A catalytic converter cleans up exhaust gases before they leave the car. If it fails, the car can run poorly and may trigger emissions warning lights.

Part

upper ball joints

"It needs a four wheel brake job, two upper ball joints and a, and a catalytic converter."

Upper ball joints are parts in the suspension that help the wheels move and steer smoothly. If they wear out, the car can feel loose and tires may wear unevenly.

Car

2022 Chevy Silverado

"another guy I know, Kevin, he says, yeah, whatever. 2022 Chevy Silverado four corner brake job, right? Pads, calipers, rotors, chat GPT."

They use a 2022 Chevy Silverado as an example. The idea is that AI could quickly create an estimate for a common job by using the right year-specific parts and labor info.

Term

canned jobs

"You wouldn't believe how many shop owners already know Greg that use it to build their canned jobs."

“Canned jobs” are ready-made estimate templates for common repairs. The episode suggests AI could help shops create those templates quickly for specific vehicles.

Term

four corner brake job

"2022 Chevy Silverado four corner brake job, right? Pads, calipers, rotors, chat GPT."

A “four corner brake job” means the brakes are serviced at all four wheels. It usually involves parts like pads and rotors, and sometimes the calipers too.

Term

flat rate

"[3336.0s] It's on the never never plan. And at that point, you know, the thought is we'll either put a renter, some, some other business can use this facility either as a shop or as a H VAC warehouse or who knows, a nail salon. I don't know. It's a piece of real estate. That is my retirement plan. I'm, you know, I, I don't make what your average technique, I don't take in a, in a wage what your average technician at a dealership is going to make, even flat rate."

Flat rate means a mechanic gets paid a fixed amount for a repair, based on a standard estimate of how long the job should take. If the job takes longer than expected, they may not get extra pay.

Person

David Roman

"[3424.0s] I've heard that said was frank enough to say with themselves that they're not a success story, they're a survival story. And you know, we talk a lot in the industry about how some people manage to buy themselves a job. And you know, certain segments of the industries talk on that like it's a bad thing and it's, and it's a. But I think you're one of them that, like, your days of being able to work for somebody else are done. You're not. You're unemployable, as David Roman says."

David Roman is mentioned as the person who said the idea that the technician is “unemployable.” In this conversation, it’s used to explain why some people end up better off running their own shop than working for others.

Term

bill accurately

"[3537.0s] So, yeah, I'm learning to charge. I don't want to say charge more for it. That's not the right. I'm learning to charge and bill accurately. I'm learning to. You know, earlier you would underestimate. I don't even say underestimate a job. You would quote a lot tighter because you really needed the work or felt you did."

“Bill accurately” means you charge for the right work and the right amount, not guesswork. The goal is that the final bill matches what you actually did and what you told the customer.

Person

Larry Grogan

"[3575.0s] Last one was, and this was actually Larry Grogan, the guy we bought the building from, told me this. He says, you're going to have. People are going to come and push you and they're going to promise you the world, right? And I have this. A month ago, I had a diesel truck in for a safety inspection."

Larry Grogan is mentioned as the person who shared a warning about customers trying to pressure a shop to cut prices. The host then uses that warning in a real story about a truck inspection.

Term

hoist

"[3613.0s] I'm holding that thing right. There's nothing, you know, the days of the hot safeties are over. I've always said I don't want to. Why do I want to take a bribe from you? I would rather you just pay me to fix your truck. But in this case, trucks on the hoist wheels are off. It needs a four wheel brake job, ball joint, and a set of headlights."

A hoist is the big lift in a garage that raises the car or truck so the mechanic can work underneath it.

Term

four wheel brake job

"[3613.0s] But in this case, trucks on the hoist wheels are off. It needs a four wheel brake job, ball joint, and a set of headlights. Headlights look like a bathroom window, right? So quote it. It's going to be 2500 bucks."

Term

labor times

"[3708.0s] You're the one put under the microscope and you looked at your production when it was like we took in something that we had no business touching for. For what we quoted."

Labor times are the “how long the job should take” estimates used for pricing and scheduling. If the real job takes longer, the shop may still be stuck with the original estimate.

Term

impact gun

"Broke. Broken impact gun today. You break. You break a $600 impact gun, the rest of your week is a write off."

An impact gun is a heavy-duty tool that helps loosen or tighten stuck bolts quickly. It’s the kind of tool mechanics use when regular tools can’t break something free.

Concept

mental health side of this industry

"The mental health side of this industry has got to improve. And that's the, that's the whole thing."

They’re talking about how shop work can affect people’s mental wellbeing. The claim is that the job environment can create stress and burnout, especially when technicians feel unsupported or underpaid.

Term

pay plans

"I can talk all we want about pay, pay plans and pay methods and valuing technicians."

Pay plans are how a shop decides how technicians get paid. For example, it might be based on how many jobs they do or how much work they complete.

Term
