1. failure phenomenon
The engine is hot.
2. point of failure
• insufficient coolant
• the coolant is not replaced when it deteriorates, resulting in poor heat dissipation or blockage of the channel
• too little oil
• insufficient cooling air volume
• fan blade deformation
• radiator fins distorted or internally blocked
• clogged radiator duct
• water temperature sensor or circuit failure
• thermostat cannot turn on large loop
• the pump does not work well
• the engine ignition time is wrong and the afterburn period is too long
• engine cylinder pad damaged
• cracked engine block or head
