Air Cooler Engine...

[Spiff <spiff@interport.net>]

Recently, a mechanic told me this one, I was kinda surprised to know. He 
said any air cooler are not suitable to drive continious for more than 2 
hours or 2 1/2 hours. Air cooler needs to rest after 2 hours, in other 
word, the engine itself would melt down from time to time.

Could anyone verify this one?

Thanks
