2001 Honda Accord mileage: 55,000. I need to replace the thermostat and I want to know the difference between them. You can purchase 170 degree, 180 degree, and 192-degree thermostats. What is the difference between these, and which one is the best for my car. I drive my car only in the summer months.
The difference in the thermostats is the temperature at which they open allowing coolant to flow into the radiator. We would suggest installing a 192 thermostat because that is the original factory specification. This is necessary for all of your computer engine management systems to work properly.
