E53 Coolant Hose - Water Valve

The rubber coolant hoses in your vehicle are subject to constant abuse. Being exposed to a full range of temperatures multiple times a day can degrade them easily. Actually, it's a wonder they last as long as they do being made of only rubber. However, as the years catch up to them, a split coolant hose can quickly turn into a tow home. Don't let such an inexpensive part result in a costly tow. Replace all of your rubber coolant hoses at the first sign of wear and be sure you will get to your destination.
