Where are the radiator and heater hoses located?
Radiator and Heater Hoses In a typical automotive cooling system, you’ll find at least 4 main hoses. First, the upper radiator hose leads directly from the thermostat housing (on the intake manifold or cylinder head) into the top of the radiator. Attached to the bottom of the radiator is a lower radiator hose.
How often do coolant hoses need to be replaced?
Carmakers do not consider coolant hoses a routine maintenance item, so it follows that there can be a lack of guidance about how often these hoses should be replaced. Without a specific mileage point or time interval to use as a reference, it’s crucial that you stay informed about how coolant hoses work and how they wear out.
What do you need to know about cooling system hoses?
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. Underneath the rubber outer layer is a flexible fabric reinforcement mesh.
How does the overflow hose in a radiator work?
An overflow hose runs between the radiator cap and the reservoir tank where extra coolant is stored (and added). As pressures within the cooling system change with coolant temperature, a valve in the radiator cap allows coolant to flow back into the reservoir to relieve pressure buildup which naturally occurs.

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).

What happens when a radiator hose is not replaced?
Radiator hoses circulate coolant from the radiator to parts of the engine that need to stay cool. Over time, radiator hoses can weaken. If they are not replaced when necessary, they can completely collapse, causing the engine to overheat and unable to run. In extreme cases, a collapsed hose can cause the engine to burst.
Why are radiator hoses overlooked during routine car inspection?
One reason radiator hoses are overlooked during a routine car inspection is that the hoses can be difficult to reach. The upper radiator hose runs from the radiator to the motor. You can usually see most of this hose. The lower radiator hose is harder to find.
How do I remove the lower radiator hose?
Remove the lower hose from the outlet of the water pump. Open the power distribution box in your engine bay and remove the cap. Disconnect the oxygen sensor connector retainer… and harness from the radiator hose. Remove the radiator upper tube bolt… and disconnect the radiator vent tube.
Is the thermostat on my new car overheating?
I got a new radiator, which stopped the leaking, but the car was still overheating so then we tried replacing the thermostat but it is overheating even now. I spent my entire check on getting those things fixed, what now? I just got paid again but don’t have much to spare towards getting it fixed, so I need to make it count.

How big of a radiator do you need for a Mercedes?
Below is a list of parts and tools that you will need to change the radiator on most Mercedes-Benz vehicles. Between 3 and 4 gallons. Check capacity in your owner’s manual. Mix Anti-freeze coolant and distilled water in a 50-50 ratio. Most Mercedes have the transmission cooler integrated into the radiator.
Where is the radiator connector on a Mercedes?
It is clipped to the bottom of the top radiator bracket. Locate the electrical connector on the back of the cooling fan. Mercedes E550 Cooling Fan Connector Location – Passenger side, behind the fan. Press the connector and pull it to disconnect it. Remove two U clips at each top corner of the radiator.
How do you change a Mercedes Benz radiator?
Open the drain plug on the driver’s side of the radiator and allow the engine to cool down. Make sure to have a drain pan under the radiator. On some models, the drain plug is red. Pry out the two plastic pins at each end of the top radiator bracket. Remove the upper radiator support.
Where is the cooling fan on a Mercedes E550?
Mercedes E550 Cooling Fan Connector Location – Passenger side, behind the fan. Press the connector and pull it to disconnect it. Remove two U clips at each top corner of the radiator. These clips can be removed by prying them up with a screwdriver. Slide the radiator colling fan up.
