Oil consumption. Blow-by. Excessive smoke. Loss of compression or power. A knock or other unusual engine noise. Coolant and oil mixing are serious warning signs, not something to shrug off.

Worn bearings, cylinders, turbo components or valvetrain parts can leave a light- or medium-duty diesel tired and down on power. The right fix may be a focused engine repair, a full rebuild or replacement. It depends on what’s worn and what makes sense for the truck. We inspect the problem and explain the options. No guessing.

HMS Auto and Fleet handles everything from basic oil changes to full engine rebuilds, advanced diagnostics and programming on gas and diesel vehicles. Our ASE Master certified technicians work in a 19,000+ sq. ft. Omaha shop equipped with current software, modern equipment and a full parts inventory. We’re built for the tough problems other shops can’t solve.

Cold hands don’t fix trucks.

On cold Omaha commutes and job sites, diesel trucks can take longer to reach operating temperature. A weak heater, lukewarm air, slow defroster, or foggy windshield isn’t just uncomfortable. It can become a visibility and safety issue.

The cause may be low coolant, poor coolant flow, air in the cooling system, a stuck-open thermostat, a restricted or leaking heater core, failed blend-door actuator, clogged cabin air filter, blower motor or resistor fault, HVAC control issue, refrigerant loss, compressor or condenser problem, or a leak.

Proper HVAC service means testing the whole system, not just topping off refrigerant.

HMS Auto and Fleet handles heating and A/C troubleshooting, defrost and ventilation performance, coolant and thermostat service, heater-core repairs, blower and blend-door repairs, A/C recharge and leak diagnosis, scheduled maintenance, complete gas and diesel repair, and fleet service.

With ASE Master certified technicians, professional diagnostic equipment, up-to-date software and programming capability, and a 19,000+ sq. ft. Omaha facility, we’re equipped to solve the tough issues other shops can’t.

Don’t wait for the first hard freeze. Call HMS Auto and Fleet or visit https://hmsautoandfleet.com/ to schedule heating and A/C service.

Randys right foot tested. “Why do you do this?” “Why do you add that?”
The answer: because he broke the version without it. That’s how you get robust builds- like our stage 2 Aisin. If you’ve followed long enough, you’ve seen the 15 float through whoops, go full redline hauling a 5th wheel, and conquer the likes of Pritchett canyon in Moab. That’s how you test your product.

Heat is what kills truck transmissions.

If your truck tows trailers, hauls equipment, or runs loaded every day, the automatic transmission is doing constant heavy work. Heavy loads, stop-and-go Omaha traffic, and long grades drive fluid temperatures up. Sustained heat breaks down fluid, promotes varnish and sludge, glazes clutches, and shortens transmission life, often ending in an expensive rebuild.

Don’t ignore:
• Harsh or delayed shifts
• Shuddering or slipping under load
• A burnt smell
• Dark or gritty fluid
• A transmission overheating message
• Fluid leaks

Modern 8-, 9-, and 10-speed transmissions in diesel pickups and work trucks put even more demands on fluid and clutch systems. Service intervals matter even more when the truck works hard. And overheating can point to a cooling-system or transmission-cooler problem that requires proper diagnosis, not just a fluid change.

HMS Auto and Fleet provides transmission fluid and filter service, cooling-system inspections, diagnostics, scheduled maintenance, complete gas and diesel repair, and fleet service. Our ASE Master certified technicians use up-to-date software and equipment in our 19,000+ sq. ft. Omaha facility to solve the difficult issues other shops can’t.

Protect one of the most expensive components on your truck. Omaha-area truck owners and fleet operators: call HMS Auto and Fleet or visit https://hmsautoandfleet.com/ to schedule transmission service.

A diesel truck can have a full tank and a healthy engine, but if the battery, starter, or charging system is weak, it may not get the job started.

Hard starting, slow cranking, dim lights, warning messages, or repeated jump-starts can point to more than a bad battery. Cold temperatures, high electrical demands, poor connections, alternator problems, and starter wear can all leave a light- or medium-duty truck sidelined.

HMS Auto and Fleet can test the complete starting and charging system, not just replace parts and hope the problem is solved. Our ASE Master certified technicians service gas and diesel vehicles, from daily drivers to business fleets, using professional equipment and the experience to find the real cause.

Don’t wait for a no-start at the beginning of the workday. Keep your truck ready for Omaha roads and job sites.

Nobody is holding a grudge like a 6-year-old wiper blade. 😤

That smear in the middle of your windshield isn't "definitely going to clear up," and squinting through it in the rain at 6 AM isn't the personality trait you think it is.

Your blades quit on you in stages. First it's one little streak. Then it's a full watercolor painting of the headlights coming at you. Then it's that awful squeak that tells everyone in the parking lot you have given up on life. 👻

Wiper blades are cheap. Regret is expensive. We keep them in stock and we'll have a fresh set on your rig before your coffee gets cold. We do wipers on cars, trucks, vans and full fleets, and yes, we'll check the washer fluid while we're in there.

Stop navigating by vibes. Get some blades. 🧽💦

Cargo vans are their own animal, and we work on them all day. 🚐🔧

Ford Transit. Ram ProMaster. Nissan NV / Cargo Master. Cargo, crew, and cutaway. Gas or diesel.

These vans live a hard life: loaded down, stop-and-go, always on the clock. That's exactly why they need a shop that knows them: alignments, brakes, suspension, drivetrain, and advanced diagnostics to find the issue the first time instead of the third.

If it hauls for a living, it gets treated like it. One van or a whole fleet: we've got the bay space and the techs to keep you moving.

Water and bad fuel don’t just cost you a fuel filter. They can take out the entire high-pressure fuel system. 💧

Modern common-rail diesels run their high-pressure pumps, rails, and injectors on extremely tight tolerances. Water in fuel, low lubricity, particulate contamination, or bad fuel can damage a CP4-style pump. When that pump fails internally, the metal debris it sheds travels downstream: contaminating the rail, injectors, lines, and the rest of the system.

That’s how one failed component becomes a multi-thousand-dollar fuel-system replacement.

Don’t ignore:
• Hard starting or extended cranking
• Rough idle or hesitation under load
• Loss of power
• Fuel-pressure codes
• Fuel in the oil
• Metal in the fuel filter
• Water in fuel

Early diesel-specific diagnosis and repair is cheap insurance. HMS Auto and Fleet provides light- and medium-duty diesel service, fuel-system troubleshooting and repair, advanced diagnostics and programming, scheduled maintenance, fleet service, and complete gas and diesel repair: including engines, brakes, tires, and alignments.

Our Omaha shop has ASE Master certified technicians, a 19,000+ sq. ft. facility, factory-level software, professional diagnostic equipment, a full parts inventory, and the experience to solve the tough issues other shops can’t. We also offer a new customer showroom built around a better service experience.

If your truck or fleet vehicle is showing fuel-system warning signs, don’t wait for a pump failure to make the diagnosis. Call HMS Auto and Fleet or visit https://hmsautoandfleet.com/.
