As a special vehicle, Chongqing refrigerated trucks have some precautions to pay attention to before driving to prevent unnecessary trouble during the journey. Before loading goods and driving, the refrigerated truck manufacturer recommends the following inspections:

1. The supply of diesel or gasoline fuel for refrigerated trucks should be sufficient to ensure that the engine runs at least until the next checkpoint.

2. Refrigerated truck engine oil supply should be at the (full) mark, do not overfill (replace once a year).

3. Check the coolant level gauge of the refrigerated truck to see if the coolant level is correct, and the pointer should be within the white range. If the coolant level is within the red range, it is necessary to add coolant to the coolant tank.

The usual coolant is a mixture of ethylene glycol and water (in different proportions depending on the actual situation of the product's use), and should be protected from freezing at -34 ℃. Attention: Do not open the lid of the coolant tank when the coolant is hot.
