What are the effects of not bleeding air from the coolant?

The effects of not bleeding air from the coolant: 1. Excessive air being heated can cause rapid and excessive pressure buildup. Short-distance driving may result in coolant overflow, while long-distance driving could lead to excessive pressure forcing open the reservoir cap and causing spraying. 2. The high temperature of the engine will simultaneously heat the air in the pipes, and the movement of colliding air can disrupt the normal circulation of the antifreeze coolant. Poor cooling performance may cause engine overheating and damage. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when parking in cold winter conditions. Many car owners believe that antifreeze is only used in winter, but in fact, antifreeze should be used throughout the year.
