Jeez, Dennis -- you're the very embodiment of the bearer of good tidings, aren't you? See everyone? No wonder I've developed a worrywart complex w/r/t my Vanagon! Dennis is one of the Wise Men of the List, knows whereof he speaks, and what he speaketh here be doom and gloom. -- Dolorous Edd (On the other hand, I learn something! Last week the alternator lamp comes on on the dash and battery voltage drops. My first thought [hope, actually, since I have a spare belt] is that I've dropped a belt. But was I sensible enough to pull over alongside the road immediately, unload the camping gear and open the engine compartment to inspect? No. Not at all. It was hot, the road dusty. I drove a mile or more to a prospective campsite, thinking I might be stuck there for a couple days before taking a look. I figured I had tens of minutes before the battery didn't have enough power to run the engine. BUT, a dropped belt would have meant that coolant flow would have stopped so, I had no business driving another hundred meters. My question is: if a belt is dropped, do the temp gauge/coolant lamp give sufficient time to warn of engine bakage so one can pull over?) -- RJS On 08/24/2011 04:19 PM, Dennis Haynes wrote: > Those multiple steam traumas may also done some engine damage.
