I have a 2005 Dodge Ram 1500 SLT pick up 4 wheel drive and when I start it in cold weather I get a noise coming from the engine compartment
The noise is like a "tinny rattling exhaust" sound like used to come from exhaust heat
risers that were used in older vehicles. The sound goes away after about 5 minutes when
it warms up. It has 110,000 miles on it and used to do it only on rare occasion-now
happens every time I start it. Any help would be appreciated.
