Question type: Maintenance & Repair

The noise rarely lasts more than 1 minute, but it's never happened before. i should mention that it doesn't happen when it's warmed up & the weather has been cold lately.

When you start the engine, energy is drained from the battery. When the engine fires, the alternator sends current to the battery to recharge it. That put a heavy load on the cold alternator belt. The belt squeals until it warms up and the load decreases. Now is a good time to change the belt before winter hits.

Loose or worn fan belt as person said above, regular maintainence avoids thing like this happening
