how to test water level with a harvard water level gauge
When adding water to the water tank of Harvard to test water level, be careful of the hot weather. It is better to add water when the car is cold. Open the water tank cap or the expansion pot cap (different filling positions for different models). Start the car. If there is no water in the water tank, you can add some water first, and then start the car. Slowly add or water until water overflows, and then close the lid. At the same time, you can increase the throttle to let the water temperature rise. Until the cooling fan works, when the fan stops, find a wet towel to cover the cover and slowly open it to see if it is not at the standard water level, and then look at the water level gauge. If it is not enough, add it to the position. Pay attention to it. 1. When opening the water tank cover of the hot car, be careful not to burn it. 2. No matter what season, it is better to use refrigerant. Water will cause rust, which is not conducive to heat dissipation. 3. Pay attention to exhaust air when adding water.
You don't need to look at the instrument. Open the machine cover and see that there is a rubber pipe connected to a small pot on the side of the water tank cover, which is used to fill the water tank. If the water level is lower than the lower mark, you need to add water to this small pot. And look at the water temperature gauge. If the water temperature is high, water must be added.
The component structure of the cooling system will be different for different models. Some have a white plastic water bottle. Mark Max in the upper part of the bottle and min in the middle. The coolant is normal as long as it is between the two marks. Below the minimum height of min, the coolant warning indicator (mostly in red) of the instrument will light up, indicating that there is a lack of coolant and it needs to be replenished in time. Add coolant below the upper limit of max. Try not to exceed max. Excessive coolant will cause poor circulation. The cooling water tank in the front of the engine room has a screw cap on it, and a thin rubber tube is connected to a white kettle on the side. After confirming that the coolant in the large water tank has been filled enough (close to the water tank opening), look at the side of the make-up kettle. If it is less than half of the kettle, it needs to be added to the half kettle position.
