Default HELP -- Knocking noise when cold

Hello,

Recently, I have been hearing some sort of rattling noise in the engine compartment. The noise is more pronounced underneath the car and when the car is cold -- more towards the driver side. I don't see obvious rattling parts. I know someone was discuss this issue before but search ended with no hits.

Thanks!

Does it happen when placing the car in gear??? You may have the typical belt rumble.Take it to the dealer and get the updated alternator and tensioner as described in the TSB...

Thank you for the reply. I was able to test it only while in "P" I recently had the tensioner pulley and alternator replaced... Could it be anything else?
