Question about Toyota 4Runner

1 Answer

Are the power steering lines connected to the oil lines somehow? Just before my power steering crapped out, I would top up the pump reservoir only to blow white smoke out the tailpipe all the way home. How do I know that won't happen again after I replace the power steering pump?

Hi. Your power steering pump hoses are closed looped. They run from the pump assembly to the reservoir.They do not run to any of your oil lines. Now, with that said, i would recommend to inspect your assembly for possible leaks. This is a high pressure setup that will produce leaks during hose or clamp failure. The reservoir can crack as well. This will cause fluid to leaks on the engine block or exhaust manifold, thus, causing the white smoke or burn off affect. Use the procedure below to inspect for possible loose hoses or compromised pump seals and reservoir issues.



Once you have staged your vehicle in a safe place, open the hood and locate your power steering system on your vehicle. The easiest way is to follow the part of the steering column assembly that goes through the firewall. Follow the components connected to the steering column all the way to the wheel assemblies and hoses connected to the power steering pump and reservoir. Attempt to scrub wet and dirty components around the steering system, using shop rags if the leak source is not readily apparent. Now,start the engine, rotating the steering wheel all the way from left to right several times to increase system pressure in the pump and hoses. Turn off the engine and inspect the system from the engine compartment, using a flashlight preferably. In some cases, you might have to wait one or two days for the leak to reveal itself . Next, check around the power steering pump, for possible cracks. If you find fluid around the pump case, the case is damaged and should be replaced. Some pumps are equipped with internal seals that may be replaced when necessary. Also, look around the reservoir and make sure it is in good condition. A cracked reservoir must be replaced as well.

Now, look around all fittings and hoses. A loose fitting cannot contain the high pressure in the system. Tighten clamps using a Phillips or flathead screwdriver or ratchet and socket, depending on the type of fitting or clamp used in your system. Additionally, check along the hoses for cuts. If possible, run your fingers along the length of the hose to find hidden wet spots. A hose leaking somewhere along the middle will have to be replaced. If the gash is very close to the end of the hose, you might be able to cut off the damaged part and reconnect the hose to the component. You will also need to Check the metal lines connecting the steering gear assembly to other components. A ruptured metal line must be replaced.

Lastly; Inspect completely around the rubber boots located between the ends of the steering gear assembly and the arms linking the assembly to the wheels. If fluid is leaking at either end, then the seals at the ends of the steering gear assembly will need to be replaced. If necessary, raise the front end of the vehicle using a floor jack and support it on jack stands or ramps. Once the vehicle is safely supported, inspect the steering gear assembly more closely to see if it is in good or bad condition . Make sure you check all the ares above for possible leaks or loose connections before replacing the entire pump.

    Concerning the white smoke:

    You may have an entirely different issue that may be causing the smoke discharge. This is commonly caused be a ruptured head gasket or damaged intake manifold gasket. I would have these gaskets inspected for damage, asap. Check your oil to be sure it is not in a milky state. This will confirm the gasket issues.

How to replace power steering pump on 1998 Volvo v70


Place the vehicle in park or neutral with the emergency brake. Let the engine idle. Raise the hood and remove the cap on the power steering pump reservoir. The cap will have a plastic dipstick on the end of it. Wipe the dipstick portion with a rag and screw it back down on the reservoir. Unscrew the lid and check the level indicated on a marked scale on the dipstick. The level should read at the top "Hot" mark. Low fluid level will cause the pump to whine. Fill to the appropriate level and listen for noise.
Inspect the condition of the power steering fluid with the cap off the reservoir. It should be translucent red and slightly thick to the touch. Brown, black or sudsy-looking fluid indicates contamination. Power steering fluid that has lost its viscosity (thickness) cannot properly lubricate the seals, bearings and vanes inside the pump, which will cause a high-pitched whine or squealing noise. If the fluid feels gritty between the fingers, it means rust, metal shavings and dirt has entered the reservoir.
Use a slot screwdriver to loosen the low-pressure rubber hose clamp on the bottom side of the power steering pump reservoir. Catch any drippings in a pan. Loosen the high-pressure metallic line nut on the power steering pump body with a fuel line wrench. Let the fluid drain into a pan. Remove the reservoir cap and use a used turkey baster to suck out all of the power steering fluid. Clean the inside of the reservoir with a rag wrapped around a screwdriver.
Reconnect the rubber low-pressure side hose and tighten the clamp with a slot screwdriver. Screw the metallic line nut on by hand and finish tightening it with a fuel line wrench. Fill the reservoir with new (manufacturer's recommended) power steering fluid to the top mark. Start the engine and listen for noise.
Test the tension and condition of the serpentine belt, or the individual power steering belt. The belt should not be cracked or contaminated with oil or power steering fluid. Clean the belt with alcohol. Adjust the (individual) belt for tension, using an end wrench to loosen the adjusting bolt, and a socket and wrench to slightly loosen the pump mounting bolts. Pry the pump outward with a screwdriver to tighten the slack in the belt. Tighten the adjusting bolt with an end wrench. Tighten the mounting bolts with a socket and wrench.

2005 Impala Power Steering Fluid Leak


If you recently added power steering fluid, this is a very common issue that many people come across. Power steering fluid is very commonly over filled. When the fluid reservoir is overfilled, it will flow right out over the top of the reservoir when you make a full turn either right or left. When this occurs, it gets onto your belt {s} and is then transferred all over the engine vie the belt and the air being blown back over your engine by your fan. If it is not an overfilling issue, then you have either a loose pressure line, a ruptured pressure line, a bad crimp on a pressure line or your fluid reservoir O-ring and body have somehow become separated. Pressure lines are typically easy to replace. If it is the pump and fluid reservoir, then unless you have experience at working on automobiles, I would suggest taking it to your mechanic.

Where do u put the power steering fluid?


Hi.

Most Chevys have a reservoir under the hood. The reservoir is often near to engine oil reservoir. You will need to bleed the old fluid. This can be done using a siphon or disconnecting the pump return hose. Using the siphon from the reservoir cap is easier and safer.

Here the picture of the reservoir while bleeding with a siphon on a Blazer:

Terrible whining in the steering? What could this possibly be?


Thank you for the inquiry.
For some reason power steering fluid does get contaminated and needs to be replaced. Worst case the fluid is low and you are hearing gear whine. It's a known issue with this pump to whine when the PSF is contaminated. Needs to be checked and serviced.
Here is a procedure for you Do It Your-self-ers:
You can easily change the fluid yourself, and save a ton of money.

If you follow the lines that go from the steering rack to the cooler located around the radiator area, there's a hose that comes out of the cooler, and connects with a hard line right above the left front frame rail. The connection is a simple spring clamp.

Easy but fairly messy to change. Engine OFF, lift the front of the car to get the front wheels off the ground, put a pan under the hose line, and pulled it loose from the hard line. The bad fluid will drained out, then slowly turn the wheels from side to side a bunch of times to pump out all of the fluid from the rack. When all of the fluid is out, reconnected the line, then fill the fluid reservoir with a high quality Power Transmission Fluid. You can again, turn the wheels side-to-side to get the new fluid into the rack. Then, start the car, again turning the wheels side to side. Top off the reservoir, and should not have any more noise from the power steering pump. It will take a little less than a full quart to completely refill the system.
Kind regards,
TF

Power steering pump or fluid?


From the top. The reservoir is located on the power steering pump which is ran off of a belt so it will be located in the front of the motor. Look for the cooling fan and then you will be close and should find it from there.
