Diesel diagnosis needs different tooling and a different ear. It's what we do all day, and it's why shops around the Hills send us the difficult ones.
Hard starts, no starts, power loss, limp mode and warning lights, traced with diesel-capable scan tools and live data.
Injector testing and replacement, fuel-pressure faults, lift pumps, filters and contaminated fuel.
Low boost, overboost, whistle, smoke and actuator faults. Pressure-tested before we recommend parts.
Valve and cooler faults, regeneration problems, sensors and derate conditions.
We show you the worn parts before we replace anything — and we don't replace what still has life left in it.
Pads, rotors, calipers and hardware, front and rear. Free brake inspection with any service.
Struts, shocks, control arms, tie rods and ball joints. Diagnosed on the lift, not guessed at.
The routine work that keeps everything else from becoming expensive.
Oil and filter changes, differential and transfer case fluids, coolant and brake fluid.
Fault tracing, parasitic drains, no-starts, lighting faults and damaged harnesses. Wiring diagnosis is a specialty of ours.
Recharge, leak detection, compressors and blower motors — ready for a Black Hills winter.
Testing, replacement and charging-system repair. Cold snaps find every weak battery.
Pickups, 4x4s and the electrical faults that leave you stranded — the vehicles this part of the country actually runs.
Differential and transfer case service, driveline and U-joint work, pre-trip checks.
Fault tracing, parasitic drains, no-starts, lighting faults, corroded connectors and damaged harnesses. Wiring diagnosis is a specialty of ours.
Testing, replacement and charging-system repair. Cold snaps find every weak battery.
How a job runs
Call or send the form. Describe what it's doing — that's usually worth an hour of diagnosis.
On the lift, with the right tooling. We confirm the fault before we quote anything.
The number you're given before work starts is the number you pay. Any extra, you get a call first.
Road-tested before it leaves the shop. We'll call you if anything changes during the job.
The shop
We stayed small on purpose. With two mechanics, the person who diagnoses your vehicle is the person who calls you about it — no service writer in between, no rotating cast of faces.
Reviews
"These guys were totally honest with me about what my vehicle's issue was and they helped get me an affordable fix. They were great to work with and helped me in a huge way. My new go-to shop in town for sure."
"Gabe and Andy did an excellent job of diagnosing what was potentially going wrong with my vehicle. As soon as the diagnostics was done, Gabe called me — he was very articulate and laid out three different options we had and what the cost breakdown was going to be. We were able to come to a decision we both felt comfortable with. As soon as a decision was made, Andy got right to work and had my truck back to me same day. Great work, boys!"
"These guys are the absolute best! Cannot say enough good things about them. I have a Ford diesel and they went way above and beyond to help me out. They diagnosed the problem super quickly (a blown A/C compressor that was about to leave me stranded on the road) and fixed it with no hangups, no upsell, and no hassle. These are salt of the earth people who just do what they say they're going to do."
"Rolled into town from Texas on a holiday weekend with my check engine light on. Found Culver Mechanics on Google Maps and gave a call. Gabe checked the code and diagnosed a fuel issue. He ordered parts and had my 2500 on the road in under 2 hours — including great conversation while waiting on parts. Simply amazing service."
"I had to pull over in Sturgis because I had a low tire pressure light come on — turns out I had a nail in my tire and I had a 6 hour drive home. When I got out to check it, Gabe pulled up and asked if I needed help. He said right away that he has a shop and that he could plug it for me, and he did just that! Super nice guy and so thankful he stopped to check on me. Would highly recommend."
"I appreciate you guys for helping me out with my car on short notice. Definitely the guy to come to for your automotive needs. I'm definitely stopping through next time I'm traveling across states for maintenance and a check-up on my vehicle. And again, thank you so much."
We work on all gas and diesel vehicles
About the shop
A husband-and-wife shop built on written estimates and doing the work the vehicle actually needs — nothing more.
We don't charge for an estimate. You get it in writing before any work starts, with no verbal ballparks that grow later.
Time spent tracing a fault — electrical gremlins, intermittent no-starts, check-engine codes — is charged, and we'll tell you before we start. The estimate that follows is free.
Foreign and domestic, cars through tow rigs. If you drive it, we'll look at it.
Injectors, turbos, fuel systems and diagnostics — the tooling most shops don't carry.
You hear the price and what it covers before we begin — no figures invented on the invoice.
If we find something else while we're in there, you hear about it first.
Rally week, I-90 and out-of-state plates — call ahead and we'll tell you what we can fit in.
The people
Founded the shop and still turns wrenches daily. Diesel drivetrain and electrical diagnostics are his specialty, and he signs off on every estimate.
Keeps the business running behind the scenes — the numbers, the ordering and the admin that keeps the shop on an even keel. She and Gabe have owned Culver Mechanics since October 2025.
Runs the desk. He takes your booking, writes your estimate and calls you with what the shop finds. If you ring the shop or send the form, Will is who you'll hear back from.
Runs the bay and keeps the schedule moving. Brakes, suspension, front-end work and diagnostics — usually the one who calls with what he found.
We're a repair and maintenance shop, not a body shop or a dealership. If a job needs a specialist beyond us, we'll say so and point you somewhere that helps.

Our specialty
The tooling is different, the failure patterns are different, and a generic code reader won't get you far. This is the work we're set up for.
The jobs that bring diesels here
Hard starts, no starts, power loss, limp mode and warning lights, traced with diesel-capable scan tools and live data. Diagnostic time is charged; the estimate that follows it is free.
Injector testing and replacement, fuel-pressure faults, lift pumps, filters and contaminated-fuel problems.
Low boost, overboost, whistle, smoke and actuator faults. Pressure-tested and confirmed before we recommend parts.
EGR valve and cooler faults, regeneration problems, sensors and derate conditions.
Winter no-starts, glow plug circuits, grid heaters and charging checks. A Black Hills cold finds every weak one.
Differentials, transfer cases, driveshafts and U-joints. Fluid services and fault diagnosis.
Bring it anyway. We work on gas engines, cars, SUVs and vans too — same shop, same standard.
Before you call
Cold start, under load, at idle, or only when towing. The condition usually narrows the fault fast.
Whistle, knock, rough idle, hard crank, exhaust note. Describe it in your own words.
And whether they flash or stay on steady — that distinction matters on a diesel.
Anything done elsewhere in the last few months, even if it seems unrelated.
Next step
Earlier is cheaper. Free written estimate before we start anything.
Everything else your vehicle needs
Cars, pickups, SUVs and vans — gas or diesel, foreign or domestic. If you drive it, bring it in.
Pads, rotors, calipers, struts and shocks. We show you the worn parts before replacing anything.
Oil changes, fluid services, filters, belts and the scheduled maintenance your manual calls for.
Recharge, leak detection, compressors and blower motors — ready for a Black Hills winter.
Testing, replacement and charging-system repair. Cold snaps find every weak battery.
Most vehicles inspected and released the same day they arrive.
An honest read on current turnaround before you set off.
Plain language, with the reason shown — not just a list of part numbers.
Rally week, I-90 and out-of-state plates all seen regularly.
