Car overheats amd power steeerong wont turn fluid is good and new pumo amd hoses what is the cause

My car has 255000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hello, thanks for writing in. Assuming the power steering system has been properly bled, and there is no more air in the system, I suspect the pressure relief valve in the pump itself is stuck, not allowing pressure to "assist" steering effort.

If you need assistance with this, I would recommend having a steering issue inspection completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

How to Identify and Fix Common car Problems ?

Low fluids

If you have a leak in your system, low power steering fluid levels can easily overheat due to not having enough liquid to properly disperse the extreme heat of your engine. This can actually cause your power steering fluid to boil, which reduces its effectiveness and longevity.

Thick Fluid

It becomes too thick to flow freely and lubricate all the parts of the system if you don`t change it within the specified period. It especially causes steering wheel hard to turn at low speeds. The only solution is to flush the old fluid out of the system and refill it with new, fresh liquid.

The belt that turns the power steering pump also turns the water pump, so if it fails, it won`t be long before the car overheats. The coolant will boil and you might see some steam venting around the overflow tank.
Some of the major causes for hard steering are less or thick fluid in the power steering, improper tyre pressure, damaged serpentine belt, etc.
Make sure the power steering reservoir has fluid at all times during the process. If that does not work, make sure the lines are connected properly, and no leaks. If everything is correct, you either have a blocked high-side hose, or a bad seal in the steering rack.
The power steering pump operates by hydraulics, and anything that operates by hydraulics can easily be affected if air gets into the system. Any air that gets into the power-steering system will be compressed by the pump and will result in noise and difficulty steering.
Under inflated tyres reduce the grip between the road surface and the tyres, which causes steering to become heavier and less cooperative. Power steering fluid – lack of steering fluid can also be a common cause of heavy steering – reducing the pressure in the system.
Heavy steering refers to when the steering wheel of your vehicle becomes stiff, making it difficult to turn. This can be caused by a number of things, such as tyre pressure, lack of fluid oil and tyre alignment.
The most common cause of a stiff steering wheel is when you are running low on power steering fluid in your system. Often, this happens when there is a leak in the system from the pressurized hose area. Most of the time, it is due to a cracked or loose hose causing the fluid to leak out.
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
3. Grinding noise when steering. A bad or failing gearbox is typically caused by lack of proper lubrication and service. The excess heat causes metal-on-metal contact and thus creates a loud grinding noise when you turn left or right.
All you need to do is turn off your engine, then restart it so the light can reset. In most cases, it should come back on, and this only indicates that it may have thought it suspected a problem due to a mistake in the computer system.
A serious problem with a faulty power steering pump is steering that doesn`t respond. You may turn the wheel, but your vehicle may not change direction. As you can imagine, this can put you in a very dangerous situation and might even cause an automobile accident.
M-type fuse.
Constantly stiff hydraulic steering (low assist)

It`s simple to check which problem is present. Because it`s easiest start by checking the fluid, take a look at the steering fluid level and condition to find out if something has gone wrong in the system.

Automatic transmission fluid (ATF) is the same fluid used inside the automatic transmission. ATF can also be used in some power steering systems. Some ATF types include Dexron and Mercon. Synthetic power steering fluid is a non-oil-based fluid that`s created in a lab.
The power steering pump delivers power to the air conditioning compressor. A coupling inter-connects the power steering pump and the air conditioning compressor. Usually the power steering pump has an output shaft and a coupling is connected to the output shaft.
Electronic failure is when the electrical systems keeping the power steering running stop functioning. This type of failure can be caused by a fuse issue, so you can easily check the fuse box to see if one of the fuses needs replacing.
Antifreeze will cause oil to get milky and therefore ruin the power steering pump or steering assembly.
Your transmission does not have anything to do with the power steering system. Either of the two would not have any cause or effect on the other.
If you suspect your power steering is burnt either from the color or the smell, consider having your system flushed immediately. The more likely cause of “boiling” in your power steering system is actually just air getting pulled into the system and being released in the power steering reservoir.
Hydraulic Power Steering System

Using hydraulic pressure supplied by an engine-driven pump, or power steering pump, this pressure assists the motion of turning the steering wheel.

The most common vehicle symptoms associated with a worn pitman arm include play in the steering wheel, wandering, tire edge wear, and loose or erratic steering. Idler arm inspection techniques and specifications vary; have your vehicle inspected by a qualified service professional.

New power steering pump and hoses. The fluid is good too but it’s hard to turn the steering wheel. What causes it?
ANSWER : Hello, thanks for writing in. Assuming the power steering system has been properly bled, and there is no more air in the system, I suspect the pressure relief valve in the pump itself is stuck, not allowing pressure to "assist" steering effort.

If you need assistance with this, I would recommend having a steering issue inspection completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

Could the power steering pressure sensor cause my steering wheel to be hard or hard to steer?
ANSWER : Hello. The pressure switch (or "sensor") on your vehicle supplies a signal to the engine computer to increase engine idle speed as the power steering line pressure increases. If the switch were bad, what you would notice is the engine stalling or idle speed dropping very low as you turn the wheel toward the extreme left or right position.

If the engine is not slowing or stalling when you turn the wheel, then the switch is probably OK. Among the causes of excessive steering effort are very low tire pressure, low power steering fluid or trapped air in the system, damaged or loose power steering belt, and damaged steering rack.

If you would like to have this resolved, a certified professional from YourMechanic can diagnose your steering issue and follow through with needed repairs.

Hard to turn steering wheel when on park.
ANSWER : Hey there. There is a check valve in the power steering pump that quite often sticks after a rebuild. Since these are "restoration" components, they tend to sit on shelves longer than present-day parts. Tap lightly on the power steering pump housing and shaft with a hammer to "unstick" the check valve.

It is also possible that the control valve, which routes high pressure fluid to the "power assist" cylinder, is sticking or was not properly rebuilt. With this power assist system, which acts on the steering drag link to assist turning the front wheels, rather than through the gearbox itself – it is really irrelevant whether the steering gearbox is manual or power.

If you prefer some assistance with this issue, I would recommend having a steering system inspection conducted so that this issue can be repaired correctly.

Very loud pop when turning sharp left leaking transmission or power steering fluid where steering column meet rack
ANSWER : Hi there. If everything else has already been installed from the donor vehicle then it sounds like the high pressure hose is all that you need to install. The hardest part of doing this is the routing. One thing you may also want to double check is that the donor vehicle and your 2003 Escape have the same rack. There are different models depending on the model and the size of your wheels. You need to install the pressure line first, but if it does not line up then you may have the wrong rack installed. If you would like some assistance installing this hose, consider YourMechanic, as a certified mechanic can come to you to [replace your high pressure steering hose] https://www.yourmechanic.com/services/power-steering-pressure-hose-replacement

Steering wheel does not center
ANSWER : The problem to me sounds like you have worn out bushings that hold the power steering rack and pinion assembly. This is why your steering wheel gets off center in the direction of the turn. Have the steering inspected and the bushings replaced if they are bad. You should have no problems then.

hard to turn steering wheel
ANSWER : You need to have the vehicle taken to a GM dealer to perform the steering recall to fix the power assist. You say that they fixed something, but it sounds like it not repair the hard steering. Get in contact with them again to see if they can address the recall properly. If you would rather not take it back to the dealer, a certified technician from YourMechanic can come to your car’s location to diagnose the steering and can assist you with repair.

Hard to turn vehicle when car is idling. No leaking of power steering fluid under the car
ANSWER : Hi there. Chances are the power steering pump is at fault for the steering wheel being hard to turn both directions at idle. It could be, a faulty power steering pressure switch not sending a signal to the computer to raise engine rpm (revolutions per minute) to compensate for power steering load at idle. The power steering fluid level being low, indicates there is a power steering fluid leak even though, your not seeing it on the ground. Replacing components without proper diagnoses, can be expensive and time consuming without resolution. I recommend having your vehicle’s steering wheel is hard to turn at idle be diagnosed and repaired by a certified technician, such as one from YourMechanic.
