What are the common faults of car engines?

[DelJake]

Common engine faults include failure to start, lack of acceleration power, stalling during gear shifts, and excessive coolant temperature. Below are detailed explanations of engine faults: 1. Engine failure to start: When there's no response during ignition, observe the dashboard or turn on the headlights. If the lights dim during ignition, it indicates a weak battery. Use jumper cables from another vehicle to assist in starting. 2. Lack of acceleration power and stalling during gear shifts: For acceleration issues, check the air intake and fuel supply systems. The air filter and fuel filter require regular replacement, typically every year or 40,000 km. Replacement intervals can be adjusted based on fuel grade and operating conditions. 3. Excessive coolant temperature: Check if the coolant level is insufficient. Regular replenishment is necessary, and periodic replacement should also be remembered. Additionally, monitor the cooling fan. If the air conditioning operates when turned on, inspect the water temperature sensor, water pump, and upper/lower coolant circulation hoses.
