The analysis is as follows:
1. The water temperature sensor is installed on the cylinder head, just behind the intake bypass pipe, i.e. behind the generator and is difficult to replace. The 1.8 is just under the ignition coil.
2. Strictly speaking, water temperature sensors are divided into two categories. Regardless of the type, its internal structure is a thermistor and its resistance is between 275 ohms and 6500 ohms. Additionally, the lower the temperature, the higher the resistance, and the higher the temperature, the lower the resistance.
Detailed information
Water temperature sensor identification
The thermistor water temperature meter consists of a thermistor water temperature sensor and a bimetallic part. the composition is shown in Figure 1. Among them, the thermistor is the transmitter of water temperature information, and the bimetallic heating wire is the receiver, and the two are connected in series. The sending part is that the water temperature sensor is installed in the water channel and is in contact with the cooling water. When the water temperature is low, the thermistor value is high, the current in the loop is low, the heat generated by the. the resistance wire is small, the bimetallic sheet is slightly bent, and the indicator needle is at low temperature (zone C).
The water temperature sensor used by the water temperature meter is a negative temperature coefficient thermistor, which is installed in the water jacket of the cylinder head. The water temperature meter uses a water temperature sensor.

The 15 kilowatt generator uses water channel heating to heat water. When using antifreeze coolant, in cold areas where the ambient temperature is below 0 degrees Celsius, the fluidity of the liquid will become poor and the temperature inside the body will be too low, making it difficult starting the engine. Using a water heater can increase the temperature of the coolant, improve its fluidity and increase body temperature by relying on heat transfer.
