The coolant should be changed every 60,000 miles, and the spark plugs typically need to be replaced every 100,000 miles, unless they are copper, in which case they should be changed every 30,000 miles. Engine problems are common, including oil leaks that should be promptly addressed, loose gaskets that should be tightened quickly, and spark plugs that can cause engine malfunctions if they come loose. Excessive oil consumption may necessitate more frequent oil changes. One critical issue to watch out for is engine overheating, which can result in fires and even explosions.
