It is especially important to encourage the younger generation as we are only guardians of our Jeeps and the youngsters will have them one day!
It is always worth while (I feel) to engage with youngsters and show them what's in the engine bay, but you can' be with your vehicle all the time and who wants to hear an old crusty like me?.
At a local show I plastered the engine bay with "QR" codes. These are found on most products nowadays.
They can be read by youngsters with their mobile phones. It engages them and reaches them a thing or two.
The photo below shows what the engine bay looked like. Most said simple things like "Radiator - this is where hot water from the engine is cooled by the big fan" or words to that effect.
I shan't say what this QR code says - grab your smart phone and read it (you will need a QR code reader)
Each code is printed onto magnetic paper and given a quick waterproof lacquer spray
