Genuine OEM Honda Thermostats

Just like the thermostat in your home, a automobile's thermostat helps maintain a minimum temperature in order to keep the engine coolant at an acceptable temperature. During startup, and normal operation, the cooling system in your Honda is capable of handling the load just fine, and carries on as normal. During extended or hard driving periods or when the weather is hotter out, the cooling system can endure a lot more heat, and can't handle the load, which can cause the coolant temperature to rise significantly. 

The thermostat's job is to open when the coolant temperature reaches a predetermined temperature (typically 195 degrees Fahrenheit). Once the thermostat opens, more coolant is allowed to pass through the engine reducing the coolant temperature to below that level. Once the temperature goes below that threshold, the thermostat closes. Sometimes the thermostat can get stuck either open or closed, which can result in overheating, which can severely damage your Honda's engine. It is recommended to replace the thermostat if the water pump is ever replaced.

When it comes to a thermostat for your Honda, they are not all made the same. Only an Genuine OEM thermostat is designed and manufactured to work specifically for the engine you have, and is guaranteed to fit properly and is backed by Honda's Limited Parts Warranty, meaning you can rest assured once you replace the thermostat, you won't have to worry about it again.
