Where are the coolant hoses located on a BMW?
Inside this passageway will be a dedicated pipe for the coolant. One such example is found on BMW-sourced V8 and V12 engines. An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added).
Is it easy to replace radiator hoses upper and lower?
Also learn how to replace the upper and lower radiator hoses. Most radiator hoses will last over 200k miles (this one was 280k) and over 15yrs. Replacing the radiator hoses is easy for both the upper and lower radiator hoses in most cars yet they charge a lot to do the job, so do it yourself and save a ton of money!
What’s the name of the fifth coolant hose?
Bypass returns are generally short in length and are often considered a “fifth hose”. Although not commonplace, some engines such as this BMW V8 position their coolant bypass pipes internally in difficult-to-reach locations.
How do you replace a radiator water pump hose?
Install the new hose on the water pump inlet… and reservoir tube. Attach it with two new clamps by compressing them with pliers to slide them over the tube… and water inlet. Then connect the other end of the hose to the radiator outlet… and replace its clamp. Loading…

Why are the coolant hoses on my car degrading?
Coolant hoses also degrade when their outsides are exposed to direct contact with oil or other contaminants. This can occur, for example, when hot oil drips onto the rubber from a leaky engine. Also keep in mind that in addition to hot coolant from within, excess engine compartment temperatures can stress the rubber compounds.
Why do coolant hoses need to be flexible?
Reservoir tanks also feature their own pressure cap – which should not be opened while the coolant is hot. In order to withstand the vibration and movements of the engine without breaking, cooling system hoses must be flexible. To achieve this, traditional (and OEM) coolant hoses feature outer layers made of a durable rubber compound.
What kind of material are coolant hoses made out of?
To achieve this, traditional (and OEM) coolant hoses feature outer layers made of a durable rubber compound. Underneath the rubber outer layer is a flexible fabric reinforcement mesh. The mesh is designed to withstand high levels of heat and pressure.
