parts cannon

10 Episode Mentions

Too Afraid to Ask

The 'parts cannon' is when mechanics just start replacing different parts of a car to see if it fixes the problem, instead of figuring out what’s really wrong first. It can end up costing a lot of money.

Technical Definition

The term 'parts cannon' refers to a troubleshooting method where mechanics replace multiple parts in hopes of fixing a problem, rather than diagnosing the specific issue. This approach can be costly and inefficient.
