As Long as Your Serpentine Belt, (SINGLE MAIN DRIVE BELT) si in tact. I Believe you Would Know Otherwise as You would Not have Charge for Battery, And No Cooling system, Among other functions, Lights In Information Cluster Would Indicate All These Failures. First Culprit is Power Steering PUMP<<((( Check Fluid Level First If it is Low Or Empty "You Have A LEAK " Refill and Quickly Look Under Engine Compartment for Leakage, Have A Helper Turn Steering wheel if Power Assist Returns "You Have A Leak"If WHILE TURNING steering Wheel You See A Significant Amount of Fluid Pouring out This Would Indicate A "High Pressure Hose" LEAK))) IF you Have NO LEAKAGE the Problem Most Likely Resides in The Power STEERING PUMP OR The RACK This Can Be Determine By A Shop Equipped With Pressure Testing Gages.Hope this Leads you In the Right Direction, NOTE : A Hose Can Posibly Be A Do it your Selfer Beyond that Use your Own Judgment as I Dont Know Your Skill Level, Again I wish you Luck and Hope tou can Take care of this Without Getting ROBED by A Shop, If you Find This Info to Be Valuable to you Plaese RATE Me Accordingly Thank You And Have A Great Evening, RejakWilson

Bad power steering pump or rack or the belt came off. Pumps or racks will give you warning, belts will not.

My van is having a hard time turning, would this be the power steering pump going out and if so how can I fix my 1998 Mercury villager


It could be or the steering rack . The power steering system uses a CII type power steering pump (3A674) and a power rack and pinion steering gear.

If you never replaced either of these parts before suggest you take to a ASE certified repair shop .
Pump Flow and Pressure Tests Before performing pump flow and pressure test, complete the following checks for conditions which could cause loss of power assist. Take corrective action if necessary.
  1. Check power steering oil reservoir (3A697) for proper fluid level.
  1. Check tires for correct air pressure.
  1. Check drive belt (8620) for proper tension.
  1. Check power steering pump (3A674) for correct model and vehicle application.
  1. Check for correct size power steering pump pulleys (3A733) on power steering pump and engine.
  1. Check entire system for damage. Replace parts, if necessary.
If the above items are correct, or have been corrected, and the loss of assist still exists, test power steering pump flow and pressure to determine whether the trouble is in the power steering pump , power rack and pinion steering gear or hoses.

Sudden Loss of power steering whilst driving. No symptoms, noises, etc. before hand. Power steering fluid level is normal.


is the drive belt of the power steering pump intact, if the loss of assistance was immediate and the fluid level is okay it is almost certain you have lost the belt , or the tension in it has drastically dropped

I own a 2005buick lacrosse I was driving in snow and I was doing donuts (don't ask) now my steering wheel is extremely hard to turn, what could it be and is it easily fixable"


putting all the variables together( splashed up snow, high rpms, quick actions of the steering wheel requiring constant pump pressure and the sudden loss of power assist) I would suspect that the power steering belt is loose or missing or needs replacing

Loss of power and loss of vacuum to brakes


Restriction in the exhaust can cause this. Test with a vacuum gauge normal 60 mph readings around 14-18 hg. in depending on throttle position once power loss starts if reading goes to zero restriction is present. then use of a infra-red thermal heat gun you can locate the restriction. hot to cold at plugged stop.

2000 Grand Caravan, backing up from parking lot and experienced sudden and complete power steering loss. I possibly heard/felt a faint pop before it went. Definitely not the serpentine belt, and not the...


Hi Lisa, I'm not certain, but it is possible that the power steering has a separate belt. If the fluid level has remained constant and there are no noticeable leakages, a broken belt is the most likely cause. Regards John

Steering turns hard to left


Hopefully just out of alignment...due to "pot holes"...BUT PLEASE have professionally checked asap...Could be a tie rod worn or loose...AND could cause sudden steering loss...This is a free inspection at many shops.

Power steering problem is hard and dont find the power steering pomp


These vehicles have electric power steering. There is an electric motor under the steering column that provides the power steering assist. GM also had a special policy coverage on this motor as it has been notorious for causing the problems you are describing. Read on:

Some customers of 2004-2007 model year Saturn ION vehicles, equipped with electric power steering, may experience a sudden loss of power steering assist, which could occur at any time while driving the vehicle. If the power steering assist is lost, a chime will be heard and the Message Center will display a "PWR STR" warning message. The vehicle can still be steered in a safe manner but will require greater driver effort at low vehicle speeds or when stopped. Typically, the next time the vehicle is started, the power steering assist will return and the "PWR STR" message would no longer be displayed..................
This special coverage covers the condition described above for a period of 10 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Retailers are to replace the power steering motor. The repairs will be made at no charge to the customer.

The steering in my 98 Buick Century is hard to turn at low speeds. Is this a steering pump issue or the rack and pinion?


Your PS pump is fine.

This vehicle has:

Variable-assist power steering: A power steering system that uses valves and speed sensors to vary the amount of steering assist according to engine or road speed. At slow speeds more steering assist is delivered and steering the wheels is easier; necessary for parking, etc.. At higher speeds, steering assist is reduced and more steering effort is required to steer the car, giving the driver greater feel of the road. Also known as Speed-sensitive power steering.

Loss of current to the magnetic coils would cause a loss of power assist at low speed. Coil resistance can be checked with an ohmmeter, and should read about two ohms. An infinite (open) reading indicates a bad coil (requires replacing the rack since the coils are not serviceable). Checking for shorts between both sides of the coil assembly and rack housing is also recommended.

Best wishes
