Pontiac Grand Am coolant reservoir leak causing overheating and fans not activating on Pontiac Grand Am

Some Pontiac Grand Am owners report experiencing coolant reservoir leaks that lead to overheating and non-activating cooling fans. Common causes of these leaks include loose hose connections, broken radiators, and failed water pumps. Additionally, cracks in the coolant reservoir due to age or temperature changes, along with faulty caps and regular wear and tear, can contribute to the problem. Owners also note that regular maintenance, such as monthly inspections of the cooling system, is vital to catch leaks early. Furthermore, if the cooling fans do not activate during overheating, this may indicate issues with the fans or relays, necessitating a diagnostic check. In some cases, excessive pressure buildup in the system, potentially caused by a faulty radiator cap or malfunctioning pressure relief valve, can lead to coolant dumping from the reservoir. Addressing these issues promptly is essential to prevent overheating and ensure the vehicle operates efficiently.
