BMW 535i Oil Cooler Hoses

The oil cooler hose in your BMW 535i sedan may not seem like much, but it's an important part when it comes to keeping your engine cool and operating efficiently.

How Your Oil Cooler Hose Works

The motor oil lubricates the moving parts inside your engine, while also helping to cool the engine. However, the engine oil can break down because of that heat. An oil cooler hose connects to your engine and allows the hot oil to circulate out of the engine to the oil cooler, where it moves around tubes that are fitted with fins. The fins release the heat from the oil. The cooled oil is then free to return to the engine.

How to Identify Oil Cooler Hose Problems

Even the best oil cooler hose can eventually start to fail in due time. Here are some signs that your oil cooler hose is starting to go bad:

• You spot oil leakage
• You experience diminished engine performance
• You see black smoke coming from your exhaust
• The low oil pressure warning light comes on

In normal conditions, your oil cooler line should last as long as your engine. However, corrosion can occur, so it's always a good idea to regularly inspect the condition of your oil cooler hoses. While you can drive with one that's faulty, it can lead to significantly low engine oil levels – which is a precursor to engine damage. Replacing your oil cooler hose is simple, especially when you choose the right part for the job. That would be the genuine BMW oil cooler hose that's guaranteed to fit your 535i sedan.
