It'll take less than a mile to cook the engine when under load -- Sent from my Palm Pre atx wrote: The generator pulley on my 1600 SP busted this weekend. Luckily I was close to the house and got him home safely. So it's an obvious and easy repair. Is this a common failure, so I should have an extra on hand? Also, if I had been far from home, is this a stop in your tracks failure? Or could you drive a few miles with out the fan? Jeff sent via iPhone
