038 117 070A – Oil Cooler O-Ring

Description

The 038117070A Oil Cooler O-Ring creates a leak-free seal between the oil cooler and the oil filter adapter. This small but essential seal keeps engine oil contained at the cooler housing connection. Therefore, it helps maintain proper oil level, lubrication, and a cleaner engine bay.

Heat, oil exposure, and pressure cycles eventually wear down the original rubber seal. As a result, the O-ring may harden, flatten, or crack. Replacing it during oil cooler service restores dependable sealing performance.

Why This Seal Matters

The oil cooler helps control oil temperature during normal engine operation. However, the cooler and filter adapter require a secure connection to prevent oil loss. Even a small leak can leave oil residue around the housing.

Furthermore, continued leakage can create puddles under the vehicle. It can also lower the engine oil level over time. Consequently, replacing this inexpensive seal helps prevent avoidable lubrication concerns.

Signs of 038117070A Oil Cooler O-Ring Failure

Inspect the oil cooler housing area if you notice these common signs:

• Fresh oil around the oil cooler or oil filter adapter.

• Oil droplets on nearby hoses, brackets, or engine components.

• A puddle of engine oil under the vehicle.

• A burning-oil smell after driving.

• Dirt accumulation around an oily housing connection.

• A flattened, brittle, or damaged seal during oil cooler removal.

• A gradual loss of engine oil without another visible leak source.

Key Features
