What causes the car's coolant temperature to be too high?

[JourneyFitz]

There are two main reasons for the engine coolant temperature being too high. First, the cooling system's heat dissipation capacity decreases, and second, the engine generates more heat. Relevant information about antifreeze is as follows: 1. Introduction: The full name of antifreeze should be antifreeze coolant, meaning coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or cylinder head when the car is parked in cold winter. 2. Function: It provides anti-corrosion protection for the components of the cooling system; prevents scale formation and avoids reducing the radiator's heat dissipation effect; ensures the engine operates within the normal temperature range.
