01 · WHY HERNANDEZ Quality is what
Quality is what
distinguishes us.
Six values that shape every repair, every conversation, every quote.
Formality
When we say a date, we keep it. When we agree on a price, that's the price.
Bilingual service
Speak to us in English or Spanish — every visit, every phone call. No translators needed.
Order & cleanliness
A clean shop is a careful shop. Your vehicle leaves the way it came in — minus the problem.
Affordable prices
Fair pricing, always. Quality service shouldn't cost you a dealer-level bill.
Customer satisfaction
We're not done until you drive away happy — and we mean that literally.
02 · WHAT WE DO Maintenance & repairs
Maintenance & repairs
domestic and imported vehicles.
Gas and diesel — we cover the day-to-day care your vehicle needs to stay reliable.
Maintenance
Oil change
Engine oil gets contaminated with particles from normal use. We change it on schedule to keep your engine running clean.
Brake service
Brakes are the most critical safety system on your vehicle. We inspect and service pads, discs and calipers.
Antifreeze change
Essential for winter — without it, water can freeze in the radiator and damage your engine. We use the right mix for your vehicle.
Transmission services
Automatic transmission fluid, standard transmission service and differential lubricant — to keep your gear shifts smooth.
Battery change
A reliable battery powers your starter, lights and electronics. Test, replace and properly install — quick and easy.
A/C refrigerant change
When your A/C isn't cooling like it used to, the refrigerant likely needs service. We recharge and inspect for leaks.
Injector cleaning
Injectors deliver fuel to the engine. Dirty injectors cause rough idle, lost power and bad mileage — cleaning restores performance.
Engine wash
A clean engine bay isn't just looks — it helps us spot leaks, worn seals and loose connections early.
Heating services
When the cabin heat quits in the middle of a Colorado winter, it is usually the blower motor, the heater core or a stuck thermostat. We find which one and fix it.
Repairs
Welding
Exhaust, frames, brackets and structural repairs. We weld what others say can't be fixed — saving you a costly replacement.
Complete engine repair
From head gaskets to full rebuilds, timing belt and fan belt. We diagnose what your engine really needs and fix it right — no shortcuts.
Steering
Power steering, rack and pinion, tie rods. Drive straight, with no vibration in the wheel.
Gearbox
Manual gearbox service and repair — clutches, synchronizers, bearings. We bring your stick shift back to life.
Transmission
Automatic transmission service. Smooth shifts and longer life for your transmission.
Suspension
Shocks, struts, ball joints, control arms, bushings, etc. A smooth ride that keeps your tires planted on the road.
Air conditioning
A/C diagnosis and repair — compressor, condenser, evaporator and electrical faults. Beyond recharge: we fix the root cause.
Diagnostics services
Brakes, check engine light, airbag light, high beams and the rest of the warnings on your dash. We read the codes and tell you what they actually mean.
Cooling and heating
Cooling system, water pump and radiator. An engine that runs hot does not warn you twice — we fix the leak or the pump before it costs you a head gasket.
Brakes
Shocks, struts, anti-lock brakes, CV boots and axles. The parts that keep your vehicle stopping straight and riding level.
Electrical
Batteries, starters, alternators, ignition diagnosis and repair, and computer diagnostics. If it cranks slow, will not start or throws odd electrical faults, this is where we look.

05 · CUSTOMER STORIES Real customers,
Real customers,
real stories.
★★★★★
Got stranded on the highway and used their free tow service. They arrived quickly, treated me great, and fixed the problem — a broken serpentine belt — the next morning. Everything was smooth and straightforward. Really grateful to the Hernandez Diesel team.
★★★★★
I live nearby and have watched them work for years. When my SUV started acting up I went straight to them. Great communication — they called before doing any extra work and came in exactly on budget. Would go back without hesitation.
★★★★★
I brought my truck in for a suspension noise three other shops couldn't diagnose. Hernandez Diesel found it in under an hour — a rear wheel bearing. Fair price, they explained everything clearly, and it was done same day. I'm not going anywhere else.
