How to Fix a Power Steering Hose Leak

January 27, 2012

A power steering hose carries high pressure power steering fluid between the power steering pump and the power steering rack. There are 2 types of power steering hoses-a high pressure hose that carries the fluid from the pump to the rack and a low pressure hose that carries the fluid from the rack to the pump. You can probably identify a hose leak problem if you get a smell of burning oil under the hood of the car. This is usually accompanied by difficulty in steering the vehicle.

How to Fix a Power Steering Hose Leak:

  • You should park the car and lift the hood while the engine is running. To be safe, engage the emergency brake and put the gear in park.
  • It's easy to identify the place that has sprung a leak as you can see the fluid spurting out. Since this gushing fluid can cause a fire, you shouldn't drive the car with a hose leak, even without power steering.
  • Shut off the engine and try to repair the hose leak if you are on the highway and can't get it replaced.
  • To conduct a power steering hose repair, cut the damaged portion of the hose with a sharp knife.
  • Use 2 hose clamps on each side of the hose and connect the hose together using the brass knobs on each clamp. Ensure that the clamps are tight. Remember, the clamps shouldn't be too tight as this can strip the threads of the hose. 
  • After the hose is connected, replace it in its correct position.
  • Since the power steering fluid has leaked out due to the damaged hose, it's necessary to refill the fluid.
  • Once the power steering fluid has been replaced, you can start the engine and test it for further leaks.
  • You must keep in mind that this is a temporary repair and make sure you replace the hose at the earliest.

Power Steering Hose Replacement:

  • Shut off the car's engine.
  • Remove the hose at the power steering gear and allow the power steering fluid to drain into a pan.
  • Loosen and remove the fittings that hold the hose in place at the pump and steering gear.
  • Next, cap the pump and gear fittings and remove all the clips that connect the hose to the chassis.
  • Remove the hose from the chassis and replace the O-rings at the ends of the hose.
  • Then, install the new power steering hose by attaching the hose to the chassis and connecting the clips that hold it in place at the chassis.
  • Subsequently, fasten the fittings of the hose to the pump and steering gear after uncapping the latter.
  • Lastly, reattach the hose at the power steering gear.
  • The pump should be filled with power steering fluid till the recommended fluid mark.
  • Once everything is in place you can start the engine and check for leaks.

Power steering uses the principal of hydraulic pressure. This can put a lot of pressure on the hoses and wear out the rubber. Therefore it's essential that the power steering hoses of your car are checked regularly by a mechanic and replaced when required.
