What would cause a 1998 Oldsmobile achieva to overheat?

A 1998 Oldsmobile Achieva may overheat due to several factors, including a malfunctioning thermostat that prevents coolant flow, a failing water pump that impedes circulation, or a clogged radiator that restricts heat dissipation. Additionally, low coolant levels due to leaks or a damaged head gasket can also contribute to overheating. Regular maintenance and addressing any signs of engine trouble promptly can help prevent these issues.
