Main thermostat: Located on the front side of the engine, behind the water pump. It regulates the flow of coolant to and from the engine block.
Secondary thermostat (if equipped): Located on the cylinder head, just above the main thermostat. It helps control the temperature of the engine head.
To locate the thermostats on your specific model, you can refer to the owner's manual or a repair guide for your vehicle. It's recommended to consult with a qualified mechanic if you're unsure about the location or replacement of the thermostat.
