That's all very good advice.
Not only your alternator, but your engine, and just about everything else in your engine space, needs plenty of cool, fresh air. Ventilation is paramount. Your engine will have less
power and run less efficiently if you don't feed it cool air, and alternators and other such
equipment won't be as efficient and won't last as long if you don't keep them cool.
Besides what DeepFrz recommends, I would suggest a temperature
sensor in the engine space to keep an eye on the ambient temperature in there.
