Thanks for the info dsmuts. The rattling sound is heard only on a cold start-up. Once the engine is warmed up for a few minutes, the sound goes away. After it is warm, no rattling sound is heard again and for as long as the motor is started warm no rattling sound. If I remove the SC drive belt and start the engine up cold to see if it is the SC, will this damage the motor or the computer at all? thanks for any input.
