Rattling sound from engine area...
 

this rattling sound would only appear when the engine is cool,i would start the vehicle and in 30 sec the rattle would start,but only until engine warmed up completely then it was gone, so took it to the dealer they say it's the bearings in the belt tensioner, but no time to replace today, will reschedule in 2 weeks.;)

Yup it was the belt tensioner for us too.

Update;changed out belt tensioner today and thermostat housing w/gasket cause of leak. rattling sound gone.:thumbup:
