Diesel repair specialist. Diesel emissions test station. General automotive repair.

We are a local, family-owned auto and truck repair shop servicing light-duty and all-wheel drive diesel vehicles as well as domestic gas-powered pickup trucks and one of the few diesel emission testing facilities certified by the state of Colorado.

If your diesel is coming up on registration renewal, that emissions test isn’t just another box to check.
In Colorado, light-duty diesels four years and older are required to pass emissions testing to renew their registration, with older diesels needing testing more frequently.

Here’s where we make things easier. We’re one of the few state-certified facilities that can test light-duty and AWD diesels, and because diesel service and repair is what we do every day, you don’t have to bounce between a testing station and a repair shop if your truck doesn’t pass.

Want to know when your diesel needs testing, what we test, and what to expect when you come in? Click here branchautomotive.com/diesel-emissions-testing/ to learn more.

Okay, South Denver and Douglas County, we want your October recommendations. 🎃

Where’s your family heading for the best pumpkin patch, fall festival, car show, or October tradition this year? We spend plenty of time talking trucks around here, but we want to know what our neighbors are doing when they’re not behind the wheel.

Drop your favorite local spot or tradition in the comments.
You might just give another family their weekend plans!

We know a lot of you ask more from your tires than a drive to work and back. You’re pulling trailers. Hauling equipment. Heading up the mountain. Putting plenty of miles on your truck. That’s why when you bring your truck to us, we’re looking at more than whether your tires technically have tread left.

We can inspect them, rotate them, take care of that TPMS light that keeps showing up, and when it’s time for a new set, help you choose tires that make sense for your truck and how you use it.

That’s how we approach tire services.
Give us a call at (303) 771-2224 or use the scheduling link in the comments when you need us.

A diesel that fires right up on a mild October day can tell a very different story on the first freezing morning.

That’s why battery testing is part of how we think about fall car care. We’d rather show you what your batteries are actually doing now than have you find out they’re getting weak when it’s 20 degrees outside and your truck won’t start.

Colorado cold is coming. Know where your batteries stand before it gets here. Give us a call at (303) 771-2224.

Around here, diesel trucks get a lot of attention. But if there’s a gas engine under the hood of your truck, you’re absolutely welcome at Branch too. 🤗

Gas or diesel, a truck is still a truck, and we understand what you ask yours to do. Daily driving, hauling, towing, weekends in the mountains, or keeping a truck you love on the road for a long time. Our team handles gas truck maintenance, diagnostics, and repairs with the same attention we bring to our diesel work.

So yes, bring us your gas truck too.
Call us at (303) 771-2224 or use the scheduling link in the comments.

Today we’re taking a break from talking trucks because it’s Kurt’s birthday! 🎂

Kurt is one of the people behind Branch Automotive, and today we get to celebrate him. If you see him around the shop, be sure to wish him a Happy Birthday, or leave him some birthday love in the comments!

Happy Birthday, Kurt! We hope you have a great one! 🥳

Some trucks are perfectly happy on pavement.
Others spend all week staring west, waiting for Friday. 😏

With International Off-Road Day coming up tomorrow, we want to hear from the people who know the Colorado backroads better than we do. What’s your favorite trail, off-road spot, or place to get a little dirt on the truck?

Drop your favorite in the comments. 👇🏻
Bonus points if you’ve got a picture of your truck out there. 📸

Our towns have a way of reminding you pretty quickly that summer is over. For diesel owners, those first cold mornings are when the little things you didn’t notice in August can start getting your attention. That’s why we like October for Fall Car Care Month. It gives us a chance to look at your truck before you’re asking it to start on a freezing morning, pull through the mountains, or get you home in the first real snow. ❄️

That’s really what preventative maintenance is about. It’s knowing where your truck stands, taking care of what it needs, and staying ahead of things instead of waiting for your truck to make the decision for you.

And over the next few weeks, we’re going to talk about what matters for a diesel heading into a Colorado winter. No generic checklist. Just practical advice from a team that works on these trucks every day.

Want to know where your truck stands before winter? Give us a call at (303) 771-2224 or use the scheduling link in the comments.

Do you know how old your tires are? 👀

Most drivers know to check tread depth, but tire safety goes beyond how much tread is left. As tires age, the rubber can change and develop issues that may not be obvious just by looking at the tire.

Before winter driving conditions arrive, we’ll help explain what we find so you can make the right decision for your truck.

Call 303-771-2224 to schedule.

From Chevrolet Silverado HDs to GMC Sierra HDs, Ford Super Duty trucks, and Ram diesel pickups, our team works on the diesel trucks that our customers depend on every day.

Every diesel platform has its own systems, components, and service needs. Having experience with the brands and trucks coming through our doors helps us better understand what we’re looking at and how to properly care for your vehicle.

What diesel truck do you drive? Drop your make and model in the comments. We’d love to know what trucks are part of our community.

Call us at (303) 771-2224 to schedule your diesel service.
