Confirm your engine before you order
This part is engine-specific and fits the EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS) engine only. Before ordering, find your VIN / data plate in the engine bay and confirm the line marked ENGINE reads EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS). The photo below shows where to look.
Example plate shown is an EF-NS engine (chassis S100P, 659cc). Yours shows your own code on the same ENGINE line - for this part it must read EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS).

The Hijet ran several engines in this era. Confirm your engine code on the VIN plate above, not just the chassis, against the table below.

Frequently Asked Questions
How do I know if I have the EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS) engine?
Check the VIN / data plate in the engine bay - the line marked ENGINE shows your code (the example plate above reads EF-NS; yours must read EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS)). This part fits the EF-NS (EFNS) or EF-ES (EFES) or EF-TS (EFTS) engine only, so confirm the code before ordering.
Should I fit a new belt with the tensioner?
Yes - never put a used belt back on a new tensioner. Replace them together and set tension to spec for the listed engine.
Should I replace the belt at the same time?
Yes - never put a used belt back on a new tensioner; do them together.

It's pretty straight forward. The hardest part is getting the airbag wiring off the airbag. Mine was pinned on? I had to cut the plug off my airbag and then break it apart so I could use the horn plug(could probably cut that off-(since i cut it off the airbag anyway, I didn't do that). The ceramic nuggets plug into the airbag relay to shut the light off. Tape that in and plug it back in. All that fits underneath the adapter. It's fiddly but easy. The horn plugs into one of those weird rings.
Driving two vehicles. 1989 Landcruiser and 1995 Honda ACTy. Keep an eye for any parts I might need in the future. My Landcruiser parts spreadsheet is three pages long. With Oiwa Garage’s vast parts inventory I hope to be able to do the same for my ACTy.
