Home What Causes Porsche Hoses Leakage?

What Causes Porsche Hoses Leakage?

The largest and perhaps the most complex part of your Porsche engine is mechanical. But over and beyond that, hydraulics play a key role. It therefore does not come as a surprise that your Porsche engine and the hydraulics system work in tandem to guarantee you a one of a kind Porsche experience. For this to happen, your car will need different fluids which include the engine oil, the brake fluid, the washer fluid, the power steering fluid and the transmission fluid. All these fluids must move from one to another. That is where hoses come into the picture. Read on to learn more.

The Concept

Some fluids primarily run within the engine or inside a special component. This is actually the case with the transmission fluid and even the oil. Others do not. Take the engine coolant for instance. It is always stored inside the radiator as well as the overflow reservoir. It must however, run from the radiator to the engine then back to the radiator again. The power steering fluid is another good example of fluids that run through different components. It must first be moved the power steering fluid tank at the pump straight into the rack before it goes back to the power steering. This kind of movement from one component to another requires use of hoses. Unfortunately, hoses wear over time. They therefore need to be replaced. Anything else other than a timely replacement can easily mean you’ll notice fluid leaks.

Heat

Heat is yet another key reason behind hose leaks. This is especially the case with hoses inside the engine where temperatures run high once the engine is running. For instance, the coolant hose must first deal with heat from the engine before it can deal with heat from the coolant itself.

Note that rubber, with all its resilient can only last for some time. It eventually degrades. Exposure to high temperatures also weakens it eventually. So it dries up and become brittle. That’s why squeezing a dry rubber makes one feel the crunch of something dry. Rubber then rips or even decays and before you know it, a hose inside the engine or one that serves the A/C compressor starts leaking.

Contact With Sharp And Hot Surface

A wrong size hose or one that been kinked in a wrong position can easily come in contact with hot or sharp surfaces inside the engine bay. This is of course, bad. The sharp area will wear out a part of the hose and eventually cut through it. It becomes even worse where vibrations occur as the engine runs. A leak will eventually happen. A hot surface on the other hand will melt the rubber and cause leakage.

Pressure

Combine heat exposure and pressure and you have a perfect recipe for leaking. Remember most hoses inside the Porsche engine carry pressurized fluid. This is the case with the hot coolant, the pressurized brake fluid and the pressurized power steering fluid. The pressure is necessary for obvious reasons – no hydraulic system can work without it. So pressure builds inside the hose. If for one reason or another a weak spot develops, it will easily punch through and create a leak.
