Power Steering Pump Replacement Service

How much does a power steering pump replacement cost?

It depends on the type of car you drive and the auto repair shop you go to. Our mechanics are mobile, which means they don't have the overhead that repair shops have. They provide you convenience by coming to your home or office.

What is the power steering pump and how does it work?

The power steering pump is an electric-driven or belt-driven hydraulic pump that produces the hydraulic pressure required to provide power steering assist. It develops output pressures of 1,000 PSI or more. The pump output, often a rack and pinion type unit, is directed to the steering gear where the hydraulic pressure pushes on the steering rack, greatly decreasing the effort it would otherwise take to turn the steering wheel.

When should you replace your car's power steering pump?

  • Whining or groaning noise when turning. A low fluid level or trapped air can also cause noises. Noise can occur if there is problem on the pump bearings or impeller vanes. Adding fluid may not get rid of the noise and replacement of the pump might be necessary if the pump has already been operating while dry.
  • Power steering fluid leaks. Leaks can develop at threaded connections, hoses, pump seals, or on the steering rack and pinion unit. Pump seal leaks will generally need a replacement.
  • Tough steering. If you notice it is harder to turn the steering wheel, it might indicate that the power steering pump output pressure is too low, or there could be blockages in the pump or lines.
  • Damage to the pump pulley. Should the pump pulley become broken or is loose on the pump shaft, you might detect vibration, drive belt damage, or hard steering. Either the pump assembly be replaced or the pulley will have to be serviced.

How do mechanics replace the power steering pump?

  • The power steering pump is bolted to the engine through a bracket that allows for adjustment of the pump drive belt if driven by a drive belt. The drive belt is removed once the engine is cold and safe to work on.
  • If driven by an electric pump, the pump may be mounted in conjunction with the steering shaft or in conjunction with the steering rack. Removal of any dash, panel, or steering components is performed to access the pump with either a drive belt or electric pump.
  • The threaded connectors to the pump inlet and outlet are loosened and detached.
  • Any mounting brackets and bolts are removed so the pump can be removed.
  • The system is flushed if the old pump has failed terribly, or there is reason to suspect contaminants in the power steering hoses.
  • The new pump is fastened on, the pressure and return hoses attached and the system is depleted of all air. Pump is tightened to the manufacturer’s specification if it is belt-driven.
  • Lastly, the engine is run and the car is road tested to ensure normal steering effort. If a new drive belt was installed, belt tension is measured again, and adjusted as necessary, after the belt has run for a few minutes.

Keep in mind when replacing the power steering pump

  • Any belts driving the pump must be inspected and replaced as necessary. If it is driven by the belt, the pump will only produce the required hydraulic pressure at an adequate speed.
  • Power steering leaks from aged rubber hoses are not unusual and should be carefully inspected, particularly where the rubber is crimped to the steel tube. The system functions under high pressure. The fluid is flammable, and if leaking fluid happens to contact a hot engine part, a fire might start. You always want to make sure the hoses and connections are thorough.

Is it safe to drive with a power steering pump problem?

No. The pump reservoir will not hold fluid due to a large leak if the power steering pump is operated without an adequate amount of fluid. The pump could seize, which would snap the serpentine belt and likely leave you stranded. If the pump turns and there is enough fluid, but there is no power assist, it will need much greater effort to turn the steering wheel, and that presents inherent safety risks. Generally, the wisest course is to seek immediate repairs if you suspect a problem with any component in your car’s power steering system.

After having a couple bad experiences at some large shops in Calgary I came across these guys while searching for another mechanic on google. Sounded a bit too good to be true at first, but after contacting them I was emailed back a detailed quote within 30 minutes. One day later I had a friendly mechanic named Clay show up at my work to replace my timing belt, water pump AND serpentine belt; all done in the parking lot well before I needed to drive home. This is an amazing service and I hope you guys get the recognition you deserve! Thanks!read more

Great service! I had 2 quotes from other garages. 1 said I needed a water pump and the other said I needed a new radiator. Both quotes were for $750. Instamek charged me $90 and told me I needed a $28 radiator cap. I've used them 3 times and will recommend them to anyone. Convenient, knowledgable staff, and way cheaper than any garage in town. Also available evenings and Sundays.
