The 2004 Chevy Silverado has an exhaust pipe diameter of 2.75 inches. Spark plugs should typically be changed every 100,000 miles, unless using a copper one, in which case they should be replaced every 30,000 miles. Air filters should be replaced every 15,000 to 30,000 miles, while coolant should be changed every 60,000 miles. Various engine issues may arise, such as loose gaskets that should be tightened, spark plugs popping off causing problems, and the serious issue of engine overheating, which could lead to fires or explosions. Keep an eye out for excessive oil consumption, which may require oil changes sooner than expected, and promptly address any oil leaks that may occur.
