There are many reasons for high water temperature: factors such as
temperature control switches, pumps, sub fans, rusted water pipes, and poor
return water can all cause this phenomenon. The temperature of the engine water
is mainly related to whether the thermostat is working properly, whether the
water pump can establish sufficient pressure, and whether the cooling fan can
reach the standard speed. How to check if the water temperature of a forklift in
Suzhou is abnormal? A cooling system generally consists of components such as a
cooling fan, radiator, and thermostat. The cooling fan is often directly driven
by the engine, and the fan speed is consistent with the engine speed. The
control of cooling water temperature mainly relies on a thermostat.
thermostat
1. Inspection after engine start: Open the radiator water inlet cover. If
the cooling level inside the radiator is still, it indicates that the thermostat
is working properly. Otherwise, it indicates that the thermostat is not working
properly.
2. This is because when the water temperature is below 70 ℃, the expansion
cylinder of the thermostat is in a contracted state and the main valve is
closed; When the water temperature exceeds 80 ℃, the expansion cylinder expands,
the main valve gradually opens, and the circulating water in the radiator begins
to flow.
3. When the water temperature gauge indicates below 70 ℃, if there is water
flowing at the inlet pipe of the radiator and the water temperature is warm, the
main valve of the thermostat is not tightly closed during the gauge, causing
premature circulation of cooling water.
4. Inspection after the water temperature rises: In the early stages of
engine operation, the water temperature rises rapidly; When the water
temperature gauge indicates 80 and the heating rate slows down, it indicates
that the thermostat is working properly. On the contrary, if the water
temperature keeps rising rapidly and when the internal pressure reaches a
certain level, boiling water suddenly overflows, it indicates that the main
valve is stuck and suddenly opens.
5. When the water temperature gauge indicates 70 ℃ -80 ℃, open the radiator
cover and radiator drain switch, feel the water temperature with your hand. If
both are hot, it indicates that the thermostat is working normally; If the water
temperature at the water inlet of the radiator is low and there is no water
flowing out or very little water flowing out of the inlet pipe of the upper
water chamber of the radiator, it indicates that the main valve of the
thermostat cannot be opened.
