Do you have to replace the radiator hose?
Radiator hoses should be firm, but not hard. A hose that feels brittle, spongy or soft should be replaced, even if it’s just one spot on the hose that feels that way. A leaky radiator hose will cause your vehicle to lose coolant, which can cause more serious issues, like overheating.
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 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.
Where does the coolant come from in a radiator?
Overflow Hoses For The Reservoir Tank 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.

How can you tell if your car thermostat is stuck?
The hose can be very hot, so only touch it for a few seconds with your fingertips. Repeat for the bottom radiator hose. Both radiator hoses should be very warm to the touch. If one hose is very hot and the other one feels cool or even cold to the touch, the thermostat is likely stuck in the closed position. Using the Squeeze Test
What happens if the thermostat is stuck in the closed position?
However, if the thermostat gets stuck in the closed position, the coolant can’t flow through the radiator and can make your engine overheat. To quickly tell if your thermostat is stuck, watch the flow of coolant through your radiator.
Why are my coolant hoses degrading from the outside?
This coolant hose degraded from the outside. 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.
Is the lower radiator hose hot or cold?
The upper radiator hose is extremely hot, the lower radiator hose is cold. The thermostat has been replaced 3 times now. They have all been put in boiling water, and they all opened. The car has been parked on an inclined and filled with coolant, been jacked up and filled, we’ve used the cap to vent, we’ve used the bleeder to vent.
