Driving an '05 Xterra with 58K miles. For the past couple of months, there is a loud RATATAT from under the hood when I start the car. This happens more than half the time upon ignition, with increasing frequency during cold weather it seems. Now that the weather is warming, the sound is infrequent, but I don't want to develop a false sense of security. Any thoughts as to what to ask my mechanic about? Valve? Belt? Loose-fitting shielding? The car has been otherwise pretty well maintained through the years.
Many thanks for your help!
