The oil cooler in a 2003 Cadillac CTS can fail due to several factors, including internal leaks caused by wear and tear, corrosion from age, or damage from debris. Overheating can also contribute to the deterioration of the cooler's materials. Additionally, a malfunctioning engine or cooling system may increase stress on the oil cooler, leading to premature failure. Regular maintenance and monitoring of engine temperatures can help prevent these issues.
