How to replace Power Steering Pressure Line Hose of your Car
The Power Steering system of your Car consists of Power Steering pump, fluid, belt, hoses and steering gear (Rack and pinion unit). The Power Steering Hose carries high pressure fluid between the Power Steering Pump and the Power Steering Rack gear unit. There are two types of Power Steering Hoses, one the high pressure Hose & second the low pressure Hose that carries the fluid from the pump to the Rack. It consists of resistant fabric cover and a patented synthetic rubber tube that is outfitted with standard steel reusable fittings. Your Car’s Power Steering system is connected to a pressure Hose and a return Hose as it pumps the fluid from the Reservoir and further feeds it to the Steering Rack, so as when steering effort is reduced the fluid returns to the Reservoir via the return line. A hydraulic pump driven by a belt from a crankshaft pulley to provides the pressure required to operate the Power Steering system in your Car. Power Steering uses the principal of hydraulic pressure which can put a lot of pressure and wear out the rubber Hose.
You can identify a Power Steering Hose leak if you smell of burning oil or see a clear or red fluid (Power Steering fluid) underneath your Car which is eventually accompanied by difficulty in steering while driving and taking swift turns. Power Steering Systems have other fluid hoses in addition to pressure hose which can also leak and may require replacement.

Remove the Hose from the chassis and replace the O-rings with new ones at the ends of the Hose.
Then replace the new Power Steering Hose by attaching it to the chassis and connecting the clips that hold it in place to the chassis.
Fasten the fittings of the hose to the pump and steering gear after uncapping the pump as dismantled before.
After reattaching the hose at the Power Steering gear the pump should be filled with new Power Steering Fluid if available till the recommended fluid mark in reservoir.
Turn the steering wheel several times and check for the fluid reservoir to show “Add” and “Full” signs if new readings are visible then it shows that the new hoses are working perfectly. If not, repeat the steps, and add more fluid if necessary. Once everything is in place as before you can crank your Car’s engine and check for any leaks.
