What are the reasons for the high engine temperature of the Chery Tiggo 3?
2 Answers
Chery Tiggo 3 engine overheating may be caused by fan failure, insufficient coolant, and insufficient lubricating oil. Fan failure: Specific reasons include the fan electromagnetic clutch or fan motor temperature control switch acting too late or closing too early; the fan not turning at all; failure of the fan silicone oil clutch. Insufficient coolant: Insufficient coolant with excessive internal consumption, mainly due to cylinder gasket damage. Insufficient lubricating oil: This prevents the moving parts from receiving adequate lubrication, increasing frictional resistance, accelerating wear, and generating more heat. At the same time, the temperature of the lubricating oil rises, causing a corresponding decrease in the viscosity of the lubricating oil, further promoting friction, heat generation, and poor heat dissipation. This ultimately leads to engine overheating.
My Tiggo 3 also experienced engine overheating recently. While driving on the highway, the water temperature suddenly skyrocketed, which really scared me. Later at the repair shop, they found the coolant was severely low due to a minor radiator leak. The mechanic said it's common for older Tiggo 3 models (especially those over 5-6 years) to have aging small coolant hoses with holes. Other possible causes include: radiator fan failure (broken motor or electrical issues) - particularly problematic in city traffic jams, a stuck thermostat disrupting coolant circulation (requires replacement), or a worn-out water pump reducing efficiency. Regularly check coolant reservoir levels and clean radiator fins to prevent debris buildup. For safety, pull over and shut off the engine immediately if overheating occurs - continuing to drive risks severe engine damage and costly repairs. Never underestimate this symptom - early intervention is crucial.
