The spark plugs should typically be changed every 100,000 miles, unless they are copper spark plugs, which need replacement every 30,000 miles. Replace your air filter every 15,000 to 30,000 miles and the coolant every 60,000 miles. Engine issues may arise, such as loose gaskets that need tightening or spark plugs popping off causing problems. It is crucial to address engine overheating promptly to prevent potential fires and explosions. Look out for excessive oil consumption, which may require more frequent oil changes, and address any oil leaks promptly.
