Problem overview

Some Chrysler Town & Country owners report experiencing issues with oil mixing in antifreeze, often linked to the need for oil cooler replacement, which can prevent further oil leaks into the cooling system. Additionally, some owners find that warped heads may contribute to this problem, as cracks in the cylinder head or block can allow coolant to mix with oil, leading to costly repairs. Coolant leaks from O-rings, gaskets, and other components can also cause antifreeze contamination in the oil, making it crucial to address these leaks promptly. Regular maintenance, including monitoring oil levels and inspecting the oil cooler and filter housing, is recommended to help prevent these issues. Furthermore, some owners discover that a malfunctioning Positive Crankcase Ventilation (PCV) valve can lead to oil leaks even after an oil cooler replacement, highlighting the importance of ensuring the PCV valve is functioning correctly. When replacing the oil cooler, it's essential to inspect rubber O-rings for wear and check for any signs of damage to avoid recurring oil mixing problems.
