Chevrolet cooling system
Respond to overheating before investigating its cause
What does this guide cover?
Identify whether the warning appears in traffic, with the air conditioning on or after a long drive. These conditions help diagnosis but do not by themselves establish a fan or thermostat fault.
Responding to the warning
Stop safely and follow the vehicle message about switching off the engine. Seek assistance if there is steam or a severe leak.
Checking the level
Do not open the cap of a hot cooling system. Check the vehicle manual for the coolant type, mixing ratio and checking procedure.
Match the source to the vehicle version
Start with the Chevrolet Egypt library when servicing a vehicle for the Egyptian market. If an older Aveo model is not listed, ask the dealer for the manual matching the VIN; a US-market vehicle manual is not automatically a substitute.
Include the model, model year, original market and engine or transmission code in the inspection request. Do not publish the complete VIN in public comments; provide it to the appropriate organisation when needed.
