I found a Russian website that list's parts manuals by model. Here is the Google TRANSLATED page link: http://translate.google.com/translate?hl=en&sl=ru&u=http://www.megazip.ru/ru/auto&prev=/search%3Fq%3Dhttp://www.megazip.ru/ru/auto%26biw%3D1920%26bih%3D893 Just follow to your model.
Link was not working. "Not found" But I think they moved it: http://www.megazip.ru/zapchasti-dlya-avtomobilej/subaru/sambar-2158 I think that is the same, anyway it list all models for 1982 to 2011 I believe. Thanks for the info!
Well I just bought a 1990 KS4 this morning!.... What model do you have? such as year? van or truck? The VIN or Chassis # plate usually has some info on it. Not sure about the newer models and I have not looked at my 1990 yet but, inside the passenger door in the foot well on the outside wall there should be the VIN or Chassis plate with the Chassis number on it, it should also have your model number on it. If you use google chrome you can translate the pages into English,
If you don't have the VIN/Model plate as srmoose described, you can use the most honorable Krenicki-san's "Subaru Sambar Parts List spreadsheet", see the tab marked, "Applied Model Decoding" for the mfr. date range of your vehicle, and make a more scientific wild-ass-guess.... ;-)
All Sambars have the Applied Model on the VIN plate, and the code you are looking for are the first 4 characters of that. Depending on the year of the Sambar in question, the plate is either in the Passenger Footwell, Inside edge of the Drivers side door, or Drivers door jamb. It would be a 7 character long code that begins with either KS or KV on the 1990-1998 models, and TT, TV, or TW on the 1999-2010/2012 models (vans stopped at 2010, trucks went to 2012. After these date ranges they were rebranded Daihatsu Hijets). Otherwise, Megazip does have an english website; you just change the .ru to .net. Just keep in mind that their dataset is rather old, and does not include any part numbers that have updated after around 2012 (which are quite a few). There is a good amount of context that is left out in their conversion as well (same with all of the other websites that converted the catalog to a website), but it is better than nothing. https://www.megazip.net/zapchasti-dlya-avtomobilej/subaru/sambar-2158 For those of you who care, Megazip is a Russian company based out of Vladivostok. If you would prefer to not support a Russian company, I would suggest JapanParts, Amayama, or JP-CarParts, which are all Japanese companies.
