What is the Oil Cooler Hose (Automatic Transmission) all about?

The oil cooler hose is responsible for keeping the transmission and engine oil from overheating. The hose runs from the radiator to the transmission and the engine. The oil that is used to lubricate the engine and transmission circulates through the oil cooler hose to the radiator, where it is cooled down. The keeps the oil from overheating and damaging the engine and transmission.

Keep in mind:

Any time the oil cooler hose is replaced, the oil cooler pump should be inspected as well.

How it's done:

• Inspect for oil leaks
• Inspect the oil cooler hoses
• Replace oil cooler hose assembly
• Check for leaks

Our recommendation:

Your oil cooler system should be inspected during all routine maintenance and servicing. It’s also a good idea to have your oil cooler system inspected every time your oil is changed.

What common symptoms indicate you may need to replace the Oil Cooler Hose (Automatic Transmission)?

• Oil is leaking

How important is this service?

Your oil cooler system is responsible for cooling the oil in your engine and transmission. The oil circulates through the oil cooler hose and to the radiator, where the oil is cooled before returning to the engine and transmission. This oil is needed to keep the engine well lubricated. When the oil cooler hose breaks, oil will leak out of the hose, and will be removed from the system. The engine and transmission won’t have the lubrication they need, which can be harmful to both systems, and will likely cause overheating.
