Remembering them quickly

Learn each part with its job: the ラジエータ cools the coolant, the サーモスタット holds the temperature, the オイル・ポンプ pushes oil round the engine. When an item names a part you immediately think of its system, which tells you what the item is really asking.

For kanji words such as 燃焼室ねんしょうしつ, 倍力装置ばいりょくそうち and 端子たんし, learn each character: 燃焼 (combustion) + 室 (chamber), 倍力 (boost) + 装置 (device). Every kanji you learn helps you read many other words.

For work words see car mechanic vocabulary.

FAQ

Why does the test write バッテリ and not バッテリー?

Japanese automotive terminology often drops the final long vowel of loanwords: バッテリ, ラジエータ, モータ. Get used to it, because Class 3 items use this spelling.

What is the ・ between katakana words?

It separates the words of a compound name, as in シリンダ・ヘッド (cylinder head). You read it as one word.

Where can I look up more words?

The dictionary in the app has 2,520 entries in 9 groups; looking up the Japanese word, reading and short English or Vietnamese meaning is free.
