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.
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.

Where does the coolant go after leaving the radiator?
Coolant flows from the radiator, through and around the engine, and then back to the radiator once more. In the radiator, the coolant releases its heat into the atmosphere, and then starts the journey around the engine once more. It enters and leaves the radiator through two hoses – the upper and lower radiator hoses.

Can a radiator hose fail during an oil change?
In fact, it’s highly recommended that you have your radiator hoses inspected at every oil change to ensure that you can replace them before they fail. If a hose fails while you’re driving, it could be very damaging to the engine (the loss of coolant could very easily overheat the engine).
Why is the water coming from the top of the radiator?
Considering it is the top hose, the coolant is coming from the thermostat and flowing down through the radiator to be cooled. The water pump is what pushes it through the thermostat, and if you have excessive pressure, you will want to direct your attention there.

The clip pushed down is open so it can slide over and pushed up it closes to engage the groove.
Why is coolant leaking from the radiator hose?
Only problem is its leaking at the connection of the hose and plastic radiator neck that you mentioned. the leak is under neath so i cannot tell if its the hose or the plastic neck. I’m having the same problem as yours. I replaced the hose with a brand new one but still didn’t solve the problem. Any hint would be much appreciated. Thanks!

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. When you disconnect the transmission line, you may lose up to 1 quart of transmission fluid.
What causes the radiator hose to collapse on a car?
At 195°F, the thermostat should be fully open. If the thermostat fails in the closed position, the water pump will attempt to pull coolant from the radiator and that can cause the upper radiator hose to collapse. However, this stuck radiator condition will also cause the engine to overheat.
What happens to a rubber radiator hose as it ages?
Rubber radiator hoses degrade over time and lose their ability to hold their shape.Rubber hoses deteriorate with age from the inside out. But they can also be damaged by oil. If you spill oil on a rubber radiator hose, you clean it off. Deteriorated radiator hoses lose their firmness and feel “spongey”.

Why does a Datsun have a radiator cap?
Those clever Datsun engineers had it covered. Many cars use a 195 F degree thermostat along with a 14 lb. radiator cap to raise the boiling point. A radiator is more efficient at higher temperatures, because the temperature differential to the air will be greater, thus shedding heat faster.
What kind of radiator does a Datsun 1200 use?
Datsun 1200 uses a small radiator, perfectly adequate for 69HP when in good condition. Using a small radiator is good for light weight and efficiency. B110 radiator has 20% more cooling capacity than B10 unit, yet and same weight. The capacity increase was intended for high speed running.
How do you cool a Datsun 1200 Club engine?
Fill it with coolant and run the engine (with no radiator cap and heater on hot) until the thermostat opens (you will see (hot)coolant flowing rapidly across the top of the radiator), then top it up and shut the engine off, leaving it to cool comepletely. Once cold, top up the coolant and put the radiator cap on.
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.
After the coolant passes through the radiator and sheds excess heat, the coolant exits the bottom of the radiator into the lower radiator hose, bringing the cooled fluid back to the engine. What are the symptoms related to a bad radiator hose? A coolant leak may be noted from the hoses. Coolant hoses can be damaged by oil leaks, or age.
