Over time, prolonged exposure to high-temperature coolant can take a toll on your vehicle's hoses. Made from reinforced rubber, these hoses are prone to wear and failure in various ways, including splitting at hose clamps, swelling, cracking, or breaking. Any of these issues can lead to coolant loss and potentially leave you stranded. Replacing your hoses at the first sign of wear is essential to maintaining a properly functioning cooling system.

This replacement hose is designed with the correct diameter, bends, and length for a precise fit, making it an ideal solution for swelled or damaged hoses. With straightforward installation, this hose provides peace of mind, whether you're embarking on a long road trip or simply commuting to work.

When replacing your radiator hose, some coolant loss is unavoidable. Browse our website to find the exact replacement coolant and other parts for your vehicle, delivered straight to your door. Don’t forget to order a new thermostat housing as well—factory plastic units often crack or warp during removal, and replacing them ensures a complete and reliable repair.

Subject to the ravages of heat cycling during each driving cycle - rubber hoses are more susceptible to wear and fatigue than aluminum piping. BMW utilized a single part number for their aluminum pipe and hose combination - making this part typically over $100 to replace. Rein to the rescue! By supplying just the rubber component, repairs can be made quickly and cost effectively (and without the waste of scraping a perfectly good aluminum pipe!) Includes both hose clamps and rubber hose.

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the left side of the engine. Additionally, the two o-rings that seal this hose to the water pump flange and the thermostat module housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating. This is especially helpful due to its cramped location, requiring the intake manifold to be removed for replacement.
