What Cummins service Jay Malone CDJR performs

The diesel side of Jay Malone CDJR’s service department covers the full range of factory-authorized work on 6.7L Cummins Ram HD trucks — from routine maintenance through major mechanical repair. Everything we service is documented in your Ram warranty history; every part installed is OEM Mopar or Mopar-approved.

Cummins Maintenance

Engine oil and filter service using Mopar 15W-40 or 5W-40 Diesel Motor Oil (per Ram service specification). Dual fuel filter replacement (frame-mounted and engine-mounted on a 6.7L Cummins — both need to be done together at the recommended interval). DEF fluid replacement and DEF system inspection. Coolant service. Cabin and engine air filter replacement. Aisin AS69RC and 68RFE transmission service (depending on application). Front and rear differential service. Transfer case service on 4x4 Ram HD platforms.

Cummins Diagnostics & Repair

P0299 turbo underboost diagnosis. HPFP (high pressure fuel pump) inspection and replacement. Cummins injector replacement — including the all-four-at-once strategy when timing and fuel system condition justify it. EGR cooler diagnosis and replacement. Variable geometry turbo (VGT) repair and replacement. Coolant intrusion repairs. Glow plug and intake heater work. Full electronic control module diagnostics using wiTECH.

Cummins Emissions Service

DPF (diesel particulate filter) diagnostic, cleaning, and replacement. Forced and parked regen service. DEF system troubleshooting including dosing module, NOx sensors, DEF heater, and DEF tank inspection. SCR (selective catalytic reduction) catalyst service. Failed regen diagnosis — we identify the underlying root cause rather than masking it. Return-to-compliance reinstall service if your Ram HD has previously been deleted and you want to bring it back to factory spec.

Ram HD Heavy-Duty Service

Brake service for E-rated and F-rated tow applications. Steering and suspension repair on Ram HD platforms — including the radius arm bushing service that’s a known wear point. Alignment specifically calibrated for trucks that tow regularly. Heavy-duty tire service. Trailer brake controller diagnosis and integration. Winter preparation service for Minnesota cold-start conditions including block heater inspection and oil viscosity considerations.

Mopar Performance Parts (Warranty-Preserving)

Installation and consultation on Mopar Performance Parts catalog items that preserve your factory warranty — certain exhaust components, cold air intakes, approved calibrations, and Mopar-published towing accessories. The list of truly warranty-safe upgrades is shorter than most aftermarket marketing suggests, and we can advise you honestly on what’s in versus out.

“Every Cummins that comes through Jay Malone CDJR’s service drive is touched by a Mopar-certified technician using wiTECH factory diagnostic tools, with OEM Mopar parts on the shelf and a documented service history that protects your factory warranty and resale value.”

Our diesel team and what we bring to your truck

Jay Malone CDJR’s diesel service capability rests on platform-specific experience that almost no shop in our market can match. Our lead Cummins technician has been with the dealership for nearly twenty years — spanning every generation of the 6.7L Cummins since its 2007 launch, and the prior 5.9L Cummins generation that preceded it. That continuity on a single engine family is extraordinarily rare in the diesel service world. Both technicians work exclusively with wiTECH factory diagnostic systems, exclusively with OEM Mopar parts, and exclusively under Stellantis’s factory service authorization.

That depth produces pattern recognition. When a Ram HD arrives with an intermittent regen failure or a borderline HPFP symptom, the diagnostic path the team walks is shaped by hundreds of similar trucks they’ve worked on before. The same fault code that an inexperienced shop chases for three days — replacing sensors and clearing codes hoping the next attempt sticks — gets resolved at Jay Malone CDJR because the team has seen the underlying cause before.

Brady is our Service Manager. He joined Jay Malone Motors in late 2025 after spending fifteen years driving and owning his own diesel semi trucks. His background is on the customer side of the service counter — buying trucks, paying shop bills, dealing with the consequences when somebody got a diagnosis wrong on equipment he owned and operated. That perspective shapes how he runs the service drive at Jay Malone CDJR: customer time gets respected, diagnostic communication is direct, and the long-term ownership relationship matters more than maximizing a single repair order.

“Jay Malone CDJR has been a family-owned Chrysler Dodge Jeep Ram dealership in Hutchinson, MN since 2005. The dealership operates under the motto ‘Your Dealer for Life’ — the same family today as twenty-one years ago, and the same long-tenured diesel technicians on the platform that owners count on.”

Why a dealer service center vs an independent diesel shop

Independent diesel shops have a legitimate place in the diesel community. For some customers, they’re the right choice. But for Cummins pickup owners specifically — especially owners of trucks still under factory warranty, owners planning to keep the truck through resale, or owners running newer 6.7L platforms with active emissions equipment — the dealer service center delivers things an independent simply can’t.

Factory diagnostic capability

wiTECH (the official Stellantis Mopar diagnostic platform) is the same diagnostic platform Stellantis Mopar engineers use in Dearborn. Independent shops use aftermarket scan tools that read generic OBD codes but can’t access manufacturer-proprietary diagnostic routines, can’t perform module re-flashing, and can’t document service in your Ram warranty history. On a modern Cummins with dozens of interconnected emissions and powertrain modules, the gap matters.

OEM parts pipeline

Every part installed at Jay Malone CDJR on a Cummins is OEM Mopar or Mopar-approved. We have direct factory parts access, fast availability through the Stellantis Mopar parts network, and full warranty coverage on every component we install. Aftermarket diesel parts — particularly fuel filters, glow plugs, and emissions components — carry real reliability differences that show up downstream.

Warranty work authorization

If your Cummins is still under factory warranty — powertrain, emissions, extended service plan — Jay Malone CDJR can perform that work at no charge to you under the manufacturer’s coverage. Independent shops cannot. Even if your truck is out of formal warranty, Stellantis Technical Service Bulletins (TSBs) and goodwill repair programs sometimes apply, and only a Stellantis franchised CDJR dealer can submit and execute that work.

Documented service history

Every service performed at Jay Malone CDJR is documented in the Stellantis national service database tied to your VIN. That history follows the truck for the rest of its life. At trade-in or resale, a documented Stellantis service history is worth real money — buyers and dealers can verify maintenance was performed at factory authorization, with OEM parts, by trained technicians.

“The decision between a dealer service center and an independent diesel shop comes down to four things: factory diagnostic capability, OEM parts pipeline, warranty work authorization, and documented service history. On a Cummins pickup with active emissions equipment and remaining factory coverage, the dealer side of that comparison wins clearly.”

Where our diesel customers come from

Jay Malone CDJR’s diesel service area extends roughly 60 to 75 miles in every direction from Hutchinson, MN — wider than our gas reach because diesel customers will drive further for a shop they trust. The geographic mix reflects the actual diesel ownership patterns across central Minnesota: farming operations to the west, contractors and tradesmen across the southern and eastern corridor, recreational towers throughout the lakes country, and small business owners running Ram HD trucks as personal and work vehicles.

Core service area (within 25 miles): Hutchinson, Litchfield, Glencoe, Cokato, Brownton, Stewart, Dassel, Buffalo Lake. McLeod County and Meeker County are our home territory and where our daily diesel work comes from.

Mid-range service area (25-45 miles): Willmar (Kandiyohi County’s agricultural center), Waconia (Carver County), Olivia (Renville County), Annandale (Wright County), Watertown, Chaska, Hector, Buffalo. This is the corridor where customers drive to us specifically for diesel work that local options can’t handle as well.

Extended service area (45-75 miles): St. Cloud (Stearns County), Marshall (Lyon County, deep ag), Mankato (Blue Earth County), Eden Prairie and Shakopee (outer Twin Cities suburbs), Belle Plaine, New Ulm, Granite Falls, Redwood Falls, Montevideo. Customers from this distance typically drive in for major service events — HPFP work, injector replacement, comprehensive diagnostics — where the dealer-level capability justifies the trip.

Driving in from out of town? If you’re coming in from outside Hutchinson, call ahead. We can often coordinate your service appointment with a same-day or next-day completion window so the trip doesn’t require an overnight. For major diagnostic work that requires longer in the bay, we’ll work with you on scheduling and communicate clearly about timing.

Cummins maintenance basics for Minnesota owners

The 6.7L Cummins is a durable platform when it’s maintained on Ram’s recommended schedule. The trucks that go 300,000 miles without major repairs aren’t lucky — they’re maintained. The trucks that grenade fuel systems or fail emissions equipment at 80,000 miles aren’t unlucky either — they’re usually trucks that skipped intervals.

Minnesota’s climate adds a few specific considerations for Ram HD owners that Ram’s standard service intervals don’t fully address. The diesel community here deals with road salt corrosion that quietly degrades emissions sensors and fuel system components, cold-start cycles that put more wear on glow plugs and intake heaters than warm-climate operation, DEF system management at -20°F (the DEF will freeze, the heater will cycle, and the system is designed for this — but only when properly maintained), short-trip duty cycles in winter that prevent the truck from reaching full regen temperature, and a longer winter season generally that compounds all of the above.

We follow Stellantis’s factory maintenance schedule as the floor — not the ceiling. For Minnesota owners running Ram HD trucks hard (towing, agricultural use, fleet work, extended cold-weather idle), some intervals get pulled forward. The diesel team will walk through what your specific truck and use pattern justify.

What Jay Malone CDJR doesn’t do on Cummins trucks

Honesty about what we don’t do matters as much as what we do. Three things we won’t perform on Cummins pickup trucks, ever:

Diesel deletes. Jay Malone CDJR does not perform EGR deletes, DPF deletes, or tune deletes on 6.7L Cummins pickups. The position holds regardless of customer request. Federal law still prohibits emissions tampering, the financial math hurts the truck’s owner over a five-to-seven-year ownership window, and most of the customer complaints that motivate deletes have legitimate engineering fixes our team can deliver. We’ve written a separate piece walking through exactly why — including what changed in January 2026 with the federal DOJ enforcement shift, and what the warranty and resale implications actually look like. Read the full position on diesel deletes here.

Aftermarket tunes that void the factory warranty. We don’t install aftermarket tuners or programmers that put your Ram HD’s warranty coverage at risk. The Mopar Performance Parts catalog includes legitimate warranty-preserving calibrations that we’re happy to install — the much-shorter list of those is what we’ll discuss with you.

Service we’re not certified to perform. We’re honest about scope. If your Ram HD needs a specific repair that’s outside our service certifications, we’ll tell you and recommend the right resource. We won’t take work we shouldn’t.

How to schedule diesel service

Three ways to get your Ram HD in front of the diesel team.

Schedule online. Use our online service scheduler to pick a date and time that works for you, describe the issue, and confirm your appointment. Most diesel work can be scheduled within the same week. Major repairs may need additional lead time so we have the parts and bay availability lined up.

Call the service department directly. (320) 587-4748. For diesel diagnostic work especially, a phone call helps because we can ask the right questions up front — what year, what mileage, what codes (if you have a scan tool), how long the issue has been present, what conditions trigger it. That conversation often saves an hour at the bay.

Walk in. 1165 Highway 7 West, Hutchinson, MN 55350. Service hours are Monday through Thursday 7:30am to 5:30pm and Friday 7:30am to 5pm. Closed Saturday and Sunday. If you’ve got a Ram HD with an urgent diagnostic concern — warning light, fluid leak, performance drop — come in. We’ll do our best to fit you in or schedule you fast.

What to bring with you: Your truck. Your warranty documentation if you have it (we can also look up your warranty status by VIN). Any service records from prior shops. A clear description of the issue including when it started, what triggers it, and any codes you’ve seen. If a previous shop diagnosed your truck and you’re seeking a second opinion or a re-do, bring their paperwork.

Frequently Asked Questions

Does Jay Malone CDJR service all years of Cummins?

Yes. Our diesel team services every model year of the 6.7L Cummins from its 2007 launch through current model year Ram HD trucks. We also work on the earlier 5.9L Cummins platform when needed, though parts availability for the older platform varies based on Stellantis OEM supply.

Do I need an appointment for diesel service?

An appointment is strongly preferred — particularly for diagnostic work, major repairs, or anything that requires parts pre-staging. Walk-ins are welcome for urgent diagnostic concerns and we’ll do our best to fit you in. Schedule online at /schedule-service.htm or call (320) 587-4748.

How much does diesel service cost at Jay Malone CDJR?

Cost depends on the specific service. Routine maintenance (oil and filter service, fuel filter replacement, DEF service) is published on our service specials page and competitive with the market. Diagnostic work runs at our standard shop rate. Major repairs (HPFP replacement, injectors, turbo work) are quoted after diagnosis — we’ll give you a clear written estimate before any work proceeds.

Will Jay Malone CDJR service my Cummins if I didn’t buy the truck here?

Yes. We service Cummins trucks regardless of where they were purchased — including trucks purchased at another Ram or CDJR dealer, purchased used from a private seller, or purchased from an out-of-state dealer. Factory warranty coverage transfers with the truck and we honor it the same way regardless of point of sale.

Will Jay Malone CDJR service my Ram HD if it’s been deleted?

Yes, for legitimate non-emissions work — oil changes, brake service, transmission service, suspension and steering, body work. Warranty work is significantly limited on a deleted truck because the manufacturer’s coverage exclusions apply, but the service bay is open. We can also quote a return-to-compliance reinstall if you want to bring the truck back to factory spec before a trade-in or major warranty event.

Does Jay Malone CDJR perform diesel deletes?

No. Jay Malone CDJR does not perform EGR deletes, DPF deletes, or tune deletes on 6.7L Cummins pickup trucks. The position holds regardless of customer request. The full reasoning is published in a separate post on this site — covering the federal law picture in 2026, warranty implications, resale value impact, and what we recommend instead.

What diesel-specific diagnostic tools does Jay Malone CDJR have?

wiTECH (the official Stellantis Mopar diagnostic platform) — the same factory diagnostic platform Stellantis Mopar engineers use. wiTECH allows us to read every manufacturer-proprietary diagnostic code, perform module re-flashing and software updates, run guided diagnostic routines for complex emissions and fuel system issues, and document service in the Stellantis national service database. Independent diesel shops use generic OBD scan tools that cannot access most of this functionality.

How long do major Cummins repairs typically take?

Routine maintenance (oil change, fuel filters, DEF service) is usually same-day. Diagnostic work is typically same-day or next-day depending on complexity. Major repairs — HPFP replacement, injector replacement, turbo work — typically run two to four shop days from diagnosis to road test, depending on parts availability. We communicate timing clearly throughout and update you if anything shifts.

Do you provide a loaner vehicle while my Ram HD is in service?

For multi-day repairs, loaner availability depends on the truck and the timing — we’ll discuss options when you schedule. We also offer a shuttle service for shorter visits if you need a ride within the Hutchinson area.

Are there Cummins service specials available?

Yes — we run rotating service specials on diesel maintenance, including dual fuel filter packages, DEF service, and seasonal preparation packages. Current offers are on our service specials page, updated monthly.

Can Jay Malone CDJR handle warranty work on my Ram HD?

Yes. As a Stellantis franchised dealer, we’re authorized to perform all factory warranty work on Ram HD trucks — powertrain, emissions, extended service plans, and manufacturer-published Technical Service Bulletins. Independent shops cannot perform warranty work. If your truck has remaining coverage, that’s a significant reason to bring service to us.

What if my Ram HD was diagnosed somewhere else and I want a second opinion?

Bring it in. Bring the other shop’s diagnostic paperwork too. We’ll perform our own diagnostic using wiTECH and walk you through what we find — including whether the prior diagnosis was accurate, partially right, or off. Second opinions on diesel work are common and we’re comfortable having that conversation.

How do I know if my Cummins is still under warranty?

Call us with your VIN. We can look up your factory warranty status, any extended service plan coverage, and any open Technical Service Bulletins or recall campaigns applicable to your truck. Takes about five minutes.

Do you service Cummins trucks for fleet or business accounts?

We service Cummins trucks owned by individual operators, farm operations, contractors, and small business owners. For larger-scale fleet operations with significant volume, contact us directly to discuss your service needs and we’ll determine the right fit.

A note from Brady, Service Manager

I spent fifteen years driving and owning my own diesel semi trucks before I came to Jay Malone Motors. That experience shaped how I think about diesel service from a customer’s side of the counter — what works, what doesn’t, what wastes an owner’s time and money, and what actually keeps a truck running long-term.

What I tell Cummins owners who come through our drive: this is a durable platform when it’s maintained properly, and most of the catastrophic failures the diesel community talks about online are preventable with consistent service on schedule, OEM parts, and a trained eye on the truck. Our diesel team at Jay Malone CDJR has been working on the 6.7L Cummins since it launched in 2007. The depth of pattern recognition that comes from that long on one platform isn’t something we’ll oversell — you’ll see it for yourself the first time you bring us a truck with an issue that another shop couldn’t solve.

If you’re running a Ram HD as a work truck, a farm truck, a tow truck, or a personal vehicle — and you want a dealer service relationship grounded in honest communication, factory capability, and the long view on your truck’s ownership — that’s the conversation we want to have. Come see us.
