Honda Acty Timing Belt Kits — HA3, HA4 (1990-1999)
This is the job every Honda Acty owner eventually faces, and it is our best-selling collection. The factory manual says replace the timing belt no later than 100,000 km (62,000 miles), or every 7 years. Read that second number again. Every Acty on the road is decades past it. The belt is rubber, and rubber hardens and cracks whether the truck is driven hard or parked. We have packaged the job every way you might want it, from a 4-piece belt kit up to a 25-piece Mega kit that tunes the whole truck. It covers the HA3 and HA4 truck built from 1990 to 1999 with the 656cc E07A engine, both the 2WD and the 4WD. Kit contents vary, so check your chassis against the fitment on each product page before you order.
Parts and when to replace them
How to find your Honda Acty chassis number and model code
Two Actys from the same year do not always take the same parts, so order by your chassis code, not the year. Your truck carries it in two places:
- Stamped in the frame. Open the driver-side wheel well and look at the bare body metal. The chassis code and serial number are stamped right into it, something like HA3-1234567 or HA4-1234567.
- On the ID plate. Look at the passenger footwell wall, just left of where your feet sit. A small metal plate is riveted there with your model code, serial number, and trim. The color changes from truck to truck, so go by where it sits, not what color it is. It is also where the Acty Van shows its HH3 code.
