Power Steering Cooler Return Hose, BMW - E85/E86 Z4M

BMW has two hoses they call a Return Line - this is the hose running from the power steering cooler to the reservoir. It returns fluid back to the reservoir. Like the Inlet/Supply Hose it has non-reusable crimped hose clamps where the hose meets the reservoir. Leaks are very common here as the clamps loosen and the rubber hose swells.

Chances are very good that one or more of your E85/E86 Z4M power steering hoses are leaking. Power steering leaks are a not uncommon trait of BMW ownership. Most of the leaks can be traced to old hoses and fittings that have been in service for too long. Just like cooling hoses and belts, rubber power steering lines need periodic replacement. Don't wait too long to replace a leaking power steering line! It's only going to get worse and coat the underside of your engine in dirty oil. Replace them before they fail in order to save you from further headaches and expenses.

This is a Genuine BMW PS return hose with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
