As a mechanic himself, Edd understands the complexity of car parts and systems, and enjoys finding unique methods to explain complicated concepts in a simple way. He’s also a motor specialist and inventor, best known for his successful automotive show ‘Wheeler Dealers’ which ran for fourteen years. Edd has his own website: and has appeared on Top Gear, Auto Trader, Scrapheap Challenge and Fifth Gear.

Edd also supported DENSO Aftermarket at Automechanika 2018 in Frankfurt, meeting and greeting fellow vehicle enthusiasts.

An entertaining and informative day

During the filming of the video, the workshop was buzzing with activity. Edd got stuck in straight away, chatting to Richard and other DENSO employees about the different components and the best way to illustrate the complex workings of the A/C system. He also conceived the grand finale idea, which highlights how equilibrium is achieved between refrigerant temperature, volume and pressure, in a very unique way!

It proved to be an enjoyable and resourceful day, with everyone taking away new perspectives and knowledge. Watch the video to find out more.
