This o-ring sits between the oil cooler and the oil filter adapter to create a leak free seal. Over time, this seal can fail and cause a leak from the oil cooler housing, leaving you with a puddle of oil on the ground and a loss of oil in your engine. Replace your seal today and keep the oil in the engine. Recommended to be replaced any time the oil cooler is removed.

Seals the connection between the oil cooler and the filter adapter. 59x5mm

Engine Oil Cooler Gasket Failure Symptoms

External Leaks: Air-to-oil coolers are exposed to difficult road conditions and can be vulnerable to damage from rocks or other road debris.

Age/Corrosion/Rust: Due to the harsh exposure to the elements, engine oil cooler lines are susceptible to increased levels of corrosion or rust, especially at the fittings. If bad enough, the fittings can become corroded enough to leak, or at minimum lose the ability to service the oil cooler

Internal failure: Water-to-oil coolers are susceptible to internal failure, which can result in the engine coolant mixing with the engine oil. If gone unnoticed, this can result in engine failure, so it is important to regularly observe coolant or oil quality to ensure the oil cooler is in good shape, especially in older, higher-milage vehicles. Mixing water and oil will result in a "milkshake" style appearance in the fluid.

Exterior seal leaks: When replacing a water-to-oil style cooler, it is critical to also replace the seals to avoid oil or coolant leaks upon reassembly. These seals can leak either oil or coolant depending on age, mileage, and heat cycling.
