Each page here takes one assembly of a car, such as a wheel, a spark plug or a clutch, and shows it as a line drawing with a numbered ring on every part worth naming. Many are cut-aways or exploded views, because the parts people ask about sit inside.
More about these tools
Find a part by name, name the ring that lights up, or switch to Study and read what each part does. Missed parts come back at the end of the round. Every drawing prints blank or labeled.
The pages are made for auto shop students learning a unit's vocabulary, for teachers who want a blank sheet to hand out, and for drivers naming a part on a repair estimate. No drawing shows a particular make or model, and every name was checked against at least two published references. The pages teach names and do not give repair instructions.
