Where is the coolant drain port located on the Great Wall Coolbear?

[McCorbin]

Great Wall Coolbear does not have a coolant drain port. Generally, the return hose under the radiator is removed for drainage. Below is some relevant information about antifreeze: 1. Definition: Antifreeze prevents the coolant from freezing during cold winter parking, which could crack the radiator and freeze the engine cylinder block. 2. Function: It provides anti-corrosion protection for components of the cooling system. It prevents scale formation, avoiding reduced heat dissipation in the radiator. It ensures the engine operates within the normal temperature range. It must have characteristics such as anti-freeze, anti-boiling, anti-corrosion, anti-scale, and no foam, and is unaffected by seasons or regions.
