94 Taurus - radiator hose expands due to building pressure when car is running. Why?

Your coolant system is a pressurized one so some pressure is normal, if the hose is expanding it probably needs to be replaced. Check to be sure that you have a good radiator cap that has the correct psi rating for the vehicle. If the radiator cap is venting pressure into the overflow tank and it is a proper functioning cap then there may be a head gasket issue to deal with but it sounds like what you have is normal, but the radiator hose is getting old.

What could be the problem if there is no pressure in either of the hoses going to or from the radiator?
If the engine is cool, then this isn't a problem (pressure in the cooling system isn't developed by the running engine, it is developed by the heat from the running engine). However, if the hoses don't feel like they're under pressure at normal or higher operating temperature, it does indicate a possible problem. The possible problems could be anything from a blown head or intake gasket to a low or empty radiator. Regardless, if this is the case, the problem needs to be diagnosed and repaired before the engine becomes damaged.
When do you know you need a new radiator?
If your radiator is leaking then you will need to replace it. Additionally, if you find that your car is constantly running hot you will need a new radiator.
Steam is coming from the left-hand side of the radiator when running fan does kick on and it stops Does my radiator have a leak?
It may NOT be a leaky radiator. However, you may wish to check your upper and lower radiator hoses and tighten all of the fittings (if necessary), and also trace the hoses all the way down to where they meet the engine. Be on the look-out for dry-rot and be looking for spots that might be bulging out. The bulging spots could indicate that the hose is ready to burst. It is best to conduct this inspection while the vehicle IS running and HAS BEEN running for a few minutes so that it is warmed up. BE SURE to be VERY careful because radiator hoses are HOT, and engine compartments are intentionally small. P.s: IF you can identify to the location and actually SEE the steam coming directly from your radiator, then yes, you DO have leak in your radiator.
What would cause the sound of running water when accelerating in a peugeot 106?
Sounds like your water level is running low. Check the level in the radiator reservoir You may also have a leak.
Why do tires wear out in the center before the outside?
If that happens, you are running them at too high of a pressure. Consult the pressure recommendations printed on the sidewall.
Why does your radiator leak only when the car is on?
When vehicle is running: Water pump is circulating coolant and cooling system pressure is building
Where is the ac low pressure port on a 1991 Honda accord?
It is the port on the aluminum line running right behind the radiator, near the radiator cap.
Why is the coolant not staying in the car?
Most likely you have a leak when the system is pressurized (engine running and at normal operating temperature). A radiator shop will be able to pressure test your coolant system and find the leak. Could also have a cracked engine block, or a hairline crack that expands when the casing gets hot.
Does water in the reservoir circulate through radiator when engine runs?
No. When the engine is running coolant is heated and expands. Excess coolant then flows from the radiator to the expansion (overflow) tank. When the engine is shut down coolant cools and contracts drawing fluid back out of the tank to keep the radiator topped off.
What causes radiator to spurt water out while engine is running?
A hole in the radiator would do that, or a damaged radiator cap. It could be a cracked engine block that is allowing cylinder pressure into the cooling system, pressurizing the water until it breaks through a weak spot in the radiator.
Where are the transmission cooler lines for a neon?
The transmission cooler lines are located coming from the radiator on the bottom. One is for the sending and the other for return. The lines are high pressure, just as your radiator hoses are when the car is running. The lines go from the radiator to the top of the transmission.
Where is the radiator cap located on the 1990 Jeep Cherokee How do you add coolant with only uncapping the overflow and no radiator cap?
I believe the 1990 year still had the sealed system. So there is no rad cap. You can add fluid by pourig it into the overflow bottle with the vehicle running the coolant will be sucked into the system. No radiator cap exist in the 90, 91 model. You add the coolant to the coolant container (The coolant container cap is the equivalent of the radiator cap, (pressure device))and the palstic container is under pressure all the time. Be carefull when you want to open it after the car has been running. After those year models, Jeep discontinued the use of the pressure container and went back to tha radiator cap and remove the pressure coolant container.
Leaking coolant when not running?
Can be a hole in the radiator or a problem with one or more of the hoses. A mechanic can run a pressure test to see where the problem(s) are located at.
Where exactly is the ac low pressure port on 1998 grand am?
open the hood and look down. its the line running right behind the radiator and fan.
Can Antifreeze be added to a warm engine?
Yes it can, as long as the engine is running. Be careful when taking the radiator cap off thou, cause its under pressure.
What can cause no pressure in upper and lower radiator hoses if radiator radiator cap thermostat water pump and hoses have all been replaced?
Actually if car is not running hot and temp gauge is staying within range then car is probably fine. I've seen a few that didn't have a lot of pressure on hoses because the flow of coolant was just that good. If you have too much pressure on a hose then you may need to worry.
How does an automobile radiator system work?
The radiator consists of cooling fins around tubing which the coolant flows through. A water pump circulates coolant from the radiator through the engine. A smaller radiator around the dashboard makes up the car's heater. An automotive cooling system has 6 basic components; the radiator, coolant/water, pressure cap, expansion tank, thermostat, and the water pump. When an engine is running, the water pump circulates the engine coolant inside the engine. As the engine heats up, the thermostat opens (usually at above 160 degrees), which allows the engine coolant to be pumped into the radiator, through the top radiator hose. The coolant flows through tubes inside the radiator, and is cooled by air passing over the car's grill. The cooled coolant exits the radiator and reenters the engine through the bottom radiator hose. The pressure cap holds the entire cooling system under pressure, which allows the coolant to reach higher temperatures without boiling. The expansion tank holds extra coolant for the system and allows for extra capacity when the coolant expands with the heat.
