The most frequent culprit is the degradation of the internal seals or O-rings, which dry out and crack over time due to constant exposure to high temperatures and pressurized oil. For units with internal leaks, the cooler often must be replaced entirely, as accessing internal seals is impractical without specialized equipment.
Oil Cooler Leak Pressure Test: How to Detect and Confirm Leaks
This colored liquid is typically the coolant, and its presence on the ground usually points to a failed oil cooler leak. The cooler uses either air flow from vehicle movement or a secondary coolant circuit to dissipate this heat, ensuring the oil maintains the viscosity necessary for proper lubrication.
Noticeable drops in oil pressure or the oil pressure warning light illuminating. By pressurizing the cooling system and observing where the air bubbles escape, a mechanic can definitively identify a faulty cooler.

Another common cause is external damage; road debris can strike the cooler, creating cracks in the aluminum body. In some cases, a temporary stop-leak product might be used to manage a minor seep while the vehicle is driven to a repair shop.
