Your high temperature readings are a bit concerning, because you should be good on coolant for another year. You typically need to flush and fill your coolant every two years or 30,000 miles.
If you’re noticing higher-than-average readings on your vehicle’s thermometer, you could be experiencing coolant loss through a leaky gasket or damaged hose. In that case, you should get to a mechanic so they can run diagnostics.
