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
for domestic and imported vehicles.
Gas, diesel, hybrid and electric — 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 cleaning & service
Brakes are the most critical safety system on your vehicle. We inspect, clean, 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 climate.
Transmission tuning
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.
Carburetor cleaning
For older vehicles with carburetors — buildup from fuel residue affects mixture and idle. We clean it back to spec.
Engine wash
A clean engine bay isn't just looks — it helps us spot leaks, worn seals and loose connections early.
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. We diagnose what your engine really needs and fix it right — no shortcuts.
Steering
Power steering, rack and pinion, tie rods and alignment. 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, repair and rebuilds. Smooth shifts and longer life for your transmission.
Suspension
Shocks, struts, ball joints, control arms and bushings. 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.
EXCLUSIVE BENEFIT
Free 10-mile tow with every repair.
If your vehicle won't make it to us under its own power, we'll tow it in — at no extra cost — when you repair with us. For vehicles up to 10,000 lbs. Watkins, Aurora East, Bennett and surrounding areas.
