Question about 2002 Kia Sedona
I have a 2002 Sedona EX with 39K miles on it. Problem: When the car is started cold (first start of the day) and placed into gear a loud chattering noise is heard underneath the hood. If shift lever is placed into neutral, noise goes away. Noise goes away quickly after driving the car and will not reappear as long as car is "warm." Transmission fluid and filter replaced at 60 months. I recently had the battery, alternator, and belts replaced by a local mechanic.
This sounds just like a heat shield on the exhaust on the manifold. what happens is when the car is cold the metal contracts and when the car is in gear IT IS UNDER LOAD AND CAUSE THE MOTOR TO SHAKE A LITTLE MORE THEN WHEN NO LOAD (Neutral) AND THE SHIELD RATTLES MAKING THE NOISE YOU HERE. ONCE THE HEAT FROM THE EXHAUST WARMS IT UP WITCH IS FAIRLY QUICK THE METAL EXPANDS AND GOES AWAY. (sorry for the caps didn't realize it). so the most common cause it the bolts rot off from rust and the fix is going to the dealer and getting a new one with new bolts. unfortunately these are not sold aftermarket and will need to be bought from a dealer. but your local shop can do that no problem.
if you have more question please ask. good luck and thanks.
