Hino 238/258/268/338/358: Model Overview and Generations
The Hino 238, 258, 268, 338, and 358 represent Hino's lineup of medium-duty commercial trucks, widely used in delivery services, construction, and light hauling operations. These models span multiple generations, with significant design updates occurring around 2005-2010 and again after 2011. Understanding your truck's generation is crucial for ordering the correct replacement parts, as components differ between model years.
The 238 and 258 are lighter-duty models suited for urban delivery, while the 268, 338, and 358 offer increased payload capacity for demanding applications. All models share similar front-end componentry, though year of manufacture affects fitment and compatibility. Aftermarket suppliers have developed extensive catalogs for these popular trucks, making upgrades and maintenance straightforward.
Hino Headlights: Standard, Black, and Projector Options
Factory headlights on Hino medium-duty trucks provide adequate illumination for routine operations, but many fleet managers and owner-operators choose to upgrade for better nighttime visibility and improved aesthetics. The aftermarket offers four primary headlight configurations for the Hino 238-358 series.
Standard Factory-Style Headlights maintain the original appearance while offering fresh replacement units for aging or damaged assemblies. These are the most economical choice and ensure perfect fitment with existing wiring and brackets.
Black Headlight Assemblies provide a more aggressive, modern look popular in customized fleet applications. The black housing contrasts sharply with the truck's exterior, creating a premium appearance without sacrificing functionality. Browse black headlight assemblies for Hino 238-358.
Projector Headlights represent a significant upgrade in performance and styling. These assemblies use advanced optics to project a more focused, organized beam pattern that reduces glare for oncoming traffic while improving your own visibility. View projector headlight options.
Black Projector Headlights combine the performance benefits of projector technology with the distinctive black housing aesthetic. This option appeals to operators seeking maximum visibility and style impact. Shop black projector headlights.

Hino Grilles: Chrome Options and Year-Specific Fitment
The front grille is one of the most visible components on any truck, and a quality aftermarket grille can completely transform your Hino's appearance. Hino medium-duty trucks received significant redesigns between model years, resulting in two primary grille types among commonly available aftermarket options.
Chrome Grilles for 2011 and Newer Models feature polished stainless steel construction that resists corrosion and maintains a premium appearance through years of highway and urban operation. Modern 2011+ Hino trucks use a specific grille mounting pattern and size. Order chrome grilles for 2011+ Hino 238-268.
Chrome Grilles for 2005-2010 Models fit earlier-generation Hino 238-358 trucks with different bracket configurations and overall dimensions. If your truck was manufactured between 2005 and 2010, verify fitment carefully before ordering. Browse 2005-2010 chrome grille options.
Chrome grilles require periodic cleaning to maintain their polish and reflective finish. We recommend washing grilles monthly in urban environments where road salt and industrial pollutants accelerate oxidation.
Hino Bumpers: Black and White Options
Front bumpers protect your truck's radiator, engine, and frame from collision impacts while contributing significantly to overall appearance. Hino 238-358 trucks are available with both black and white bumper assemblies, and the choice often reflects fleet color schemes and personal preference.
Black Bumpers provide a sophisticated, aggressive appearance that works well on trucks painted dark colors or configured for premium commercial service. Black absorbs more heat from sunlight, which can be a consideration in high-temperature climates. View black bumper assemblies.
White Bumpers are standard on many factory Hino configurations and maintain a cleaner, more utilitarian appearance. White reflects heat effectively and hides dirt and road grime less visibly than black. Shop white bumper options.
Both black and white bumpers are manufactured from reinforced plastic composite materials that resist denting and UV degradation better than older steel designs. Replacement bumpers include all necessary mounting hardware and typically require minimal installation time.
Hino Mirror Assemblies and Replacement Components
Side mirrors on commercial trucks endure constant vibration, temperature fluctuations, and occasional contact with obstacles and other vehicles. Quality replacement mirror assemblies restore visibility and safety to your Hino 238-358.
Complete mirror assemblies for Hino 185-358 trucks include the housing, glass, internal adjustment mechanisms, and mounting brackets. These assemblies fit multiple Hino models across different generations, simplifying inventory management for fleet operations.
Mirror replacement typically takes 15-30 minutes per side with basic hand tools. Ensure power windows and mirror adjustment electronics function properly before and after installation. If your truck uses heated mirrors for winter operation, verify heating element functionality during the installation process.
Hino Front Panels and Structural Components
The area surrounding the grille, headlights, and hood includes various plastic and metal panels that contribute to structural integrity and aerodynamics. Damage to these components from collisions or years of weather exposure may necessitate replacement.
Front panels on Hino 238-268 trucks typically include the hood surround, grille opening reinforcement, and bumper supports. These components are engineered to withstand typical operating stresses while maintaining precise alignment for headlights and grille fixtures.
When ordering front panel replacements, confirm your truck's generation and clarify whether you need the complete assembly or specific sub-components. Some suppliers offer complete front-end kits combining grilles, bumpers, and panel assemblies at favorable pricing for comprehensive restoration projects.
Vacuum Pump Systems and Brake Assist Components
Hino medium-duty trucks, particularly the 238 and 258 models, often utilize vacuum-assisted braking systems that require a functioning vacuum pump. These pumps generate the negative pressure necessary for power brake operation and can wear out over 100,000-150,000 miles of service.
Signs of vacuum pump failure include increased brake pedal effort, longer stopping distances, and unusual hissing sounds from under the hood. Vacuum pumps are engine-driven components connected to the engine block and cannot typically be repaired—replacement is the standard solution.
Quality replacement vacuum pumps are engineered to factory specifications and include all necessary gaskets and seals for proper installation. If your Hino 238-358 requires brake service and you suspect vacuum system issues, prioritize this component in your maintenance planning to ensure safe operation.
Electrical Systems and Window Control Components
Power windows and electric mirrors depend on multiple electrical components working in concert. The master driver-side window switch for Hino controls all four windows in many configurations and experiences the highest usage rates among electrical switches.
Hino 238-358 electrical systems operate at 24 volts (in some configurations) or 12 volts, depending on model year and configuration. Verify your truck's electrical system voltage before ordering switches and relays to ensure compatibility.
Common electrical issues include windows that operate slowly, switches that stick or fail to respond, and mirror adjustment motors that malfunction. Most switches are modular components that can be replaced without removing entire door panels or interior trim.
If you're experiencing intermittent electrical problems, check all ground connections first—loose or corroded grounds cause many electrical gremlins in commercial trucks operating in harsh environments.
Routine Maintenance for Hino 238-358 Trucks
Maintaining your Hino medium-duty truck's appearance and functionality requires attention to several key areas. Headlights should be inspected monthly for condensation, cracks, or reduced brightness that indicates aging bulbs or failed assemblies.
Grilles and bumpers benefit from regular washing to remove road salt, industrial dust, and chemical residues that accelerate corrosion and fading. Apply protective coatings to chrome grilles seasonally, particularly in coastal areas or regions that use salt for winter road treatment.
Mirrors and windows should be tested during pre-trip inspections to ensure full visibility and proper operation. Address minor fogging or adjustment issues immediately rather than delaying until they affect safety.
Battery terminals, ground cables, and wiring harnesses should be inspected annually, especially on trucks operating in high-vibration applications. Loose connections cause electrical problems that often seem unrelated to their source.
Ordering Guide: Finding the Right Parts for Your Hino
