What are the causes and solutions for engine overheating?

[DiMelanie]

Engine overheating can be caused by: 1. Insufficient or leaking coolant, which can be resolved by replenishing the coolant and identifying the cause of any leaks; 2. Blockages on the exterior or interior of the radiator, affecting heat dissipation or coolant circulation, which can be addressed by cleaning the radiator or replacing it. If the overheating is due to poor grounding between the engine and the vehicle frame, leading to inaccurate readings from the coolant temperature sensor and causing the temperature gauge to display false readings, the solution is to have a professional electrician inspect it or to handle it yourself. If you choose to do it yourself, simply run two grounding wires from the negative terminal of the battery to the engine and the vehicle frame to resolve the issue.
