Engine squeals, and smokes! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Every once in awhile when I haven't started my truck in a long time, (say a month) the engine will squeal and smoke will appear under the hood. 87 5.7 tbi. Is it possible this is a belt? I hope so. What would cause an old engine to squeal and smoke? It generally won't do it if its been started recently.

First guess would be alternator freezing up when it sits, causing belt slippage.

I'm assuming you did look for a loose belt first?
