[net.auto] engine heaters summary

dave@uwmcsd1.UUCP (Dave Rasmussen) (12/11/85)

Here are the messages I've thus received concerning engine heaters. If I
decide to go ahead with installing one I'll probably use the freeze-plug
type, but since my car is starting okay I'll probably forego it this season.
Thanks to all who responded.
