Frequently Asked Questions
How do I know I need the timing belt and tune-up done?
If the belt age is unknown on a used import and the truck idles rough or starts poorly, both jobs are due. Read the plugs, check the cap, and treat an undocumented belt as overdue.
How long should I budget for this job?
It is a weekend job for most - the timing belt portion is the slow part, so give yourself time to set the marks carefully.
Should I replace the water pump while I am in there?
Yes - it sits in the same area, so doing it now costs only the part, not a second teardown.

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.
