The Top 10 Most Important Parts for the Honda Acty
The Honda Acty is known for its reliability, efficiency, and clever engineering—but like any vehicle, its performance and longevity depend on proper maintenance. Whether you’re daily driving, working, or restoring an Acty, these are the top 10 parts every Honda Acty owner should prioritize.
1. Oil Filter & Engine Oil
Regular oil changes are the single most important maintenance task for your Acty.
-
Protects the E07A engine from premature wear
-
Improves fuel efficiency and engine smoothness
-
Should be changed every 3,000–5,000 km depending on usage
Tip: Always use an oil filter designed specifically for the Acty to ensure proper oil flow.
2. Air Filter
A clean Honda Acty Air Filter ensures your Acty breathes properly.
-
Improves throttle response
-
Helps maintain fuel economy
-
Reduces carbon buildup inside the engine
Clogged air filters are one of the most common causes of power loss in older Kei trucks.
3. Spark Plugs
Spark plugs are critical to smooth starting and combustion.
-
Worn plugs cause rough idle and poor cold starts
-
Fresh plugs improve power and fuel efficiency
-
Inexpensive and easy preventative maintenance
Replacing spark plugs is one of the fastest ways to “wake up” a tired Acty.
4. Timing Belt
This is one of the most critical parts on the Honda Acty.
-
Failure can cause severe engine damage
-
Recommended replacement interval: ~100,000 km or sooner
-
Should be replaced with the tensioner, idler, water pump and thermostat
If you don’t know when it was last changed—replace it immediately.
5. Brake Pads & Brake Rotors
Stopping safely is just as important as going.
-
Actys use front brake pads and rotors, and rear drum brake shoes and drums
-
Worn brake pads reduce stopping power and increase rotor/drum wear
-
Essential for safety and inspections
These are critical components for the safety of your vehicle
6. CV Axles & CV Boots
The Acty’s compact drivetrain relies heavily on CV axles.
-
Torn CV boots lead to grease loss and joint failure
-
Clicking noises when turning are a warning sign
-
Replacing boots early can save the entire expensive axle
This is a very common wear item on older Actys.
7. Suspension Components (Shocks & Bushings)
Good suspension keeps your Acty comfortable and stable.
-
Worn shocks cause bouncing and poor handling
-
Old bushings lead to clunks and uneven tire wear
-
Fresh suspension dramatically improves ride quality
Many owners are shocked at how much better their Acty drives after suspension refresh.
8. Cooling System Parts (Radiator, Thermostat, Hoses)
Overheating is one of the biggest threats to Kei engines.
-
Aging radiators and hoses can fail without warning
-
A stuck thermostat can cause overheating or poor warm-up
-
Preventative replacement avoids catastrophic engine damage
Cooling system maintenance is especially important on imported vehicles.
9. Clutch Kit
For manual Actys, the clutch is a high-wear component.
-
Slipping clutch reduces power and drivability
-
Worn clutches are common on work-used trucks
-
Best replaced as a complete kit (disc, pressure plate, bearing)
A new clutch restores factory-smooth shifting.
10. Fuel Filter
Often overlooked—but extremely important.
-
Prevents debris from damaging injectors or carburetor
-
Improves throttle response and idle quality
-
Especially important for older fuel systems
A clogged fuel filter can mimic much more serious engine problems.
