Is the Wuling Hongguang warm air tank linked to the thermostat?

Wuling Hongguang warm air water tank is linked to the thermostat. There is nothing wrong with the thermostat. Connect the inlet pipe and outlet pipe of the warm air tank directly with an iron pipe to see if it is normal. Everything that needs to be changed has been changed, and the thermostat must be exhausted after installation. The exhaust hole is upward, and the copper temperature sensing element is installed in the direction of the engine. After the installation is completed, start the engine oil filler door, and check whether there is a thin tube that circulates the water to get the engine out of the water replenishing kettle at 15 rpm to 2 rpm.
