Replacing power steering hoses

Replacing power steering hoses is performed when power steering fluid leaks, cracks, and bulging hoses are found during the check. Always refer to the manufacturer’s service information before starting a replacement.

Power steering hoses

Steering fluid is under pressure in the supply hoses. When the hose bursts, it comes out under pressure and falls on the hot engine and exhaust system. The hot parts cause the power steering fluid to smoke and catch fire. Small leaks or leaks in the return line result in a low fluid level in the power steering pump reservoir and fluid ends up on the floor under the vehicle. If the steering fluid level gets low enough, it can cause a buzzing sound while driving. This noise is louder when steering the vehicle. If any of these symptoms are present, or to catch problems before they become this serious, the power steering hoses must be inspected regularly and replaced at any sign of wear.

Never attempt to patch or plug a leak at a hose or fittings. Hoses must not rub against other components as this can create a hole. The high-pressure hoses are multi-layered from rubber-coated braided steel with cast steel fittings at each end.

To replacing power steering hoses, follow these steps:

Removal of hoses

Place the container under the vehicle. While the engine is off, remove the return hose from the reservoir or steering rack. Allow the power steering oil to drain into the drain pan. Loosen and remove all defective hose connections from the pump and steering wheel. Remove the hose.

Hose assembly

Before installation, compare the new and old hoses. Lubricate new seals or O-rings with steering fluid and install them on fittings. Mount the new hose on its connections and tighten it with the force specified in the instructions.

Checking the condition

If the drain hose was changed, connect it back. Pour new power steering fluid into the reservoir to the maximum. Perform bleeding from the system according to the given procedure. Start the engine and after a short warm-up, turn the steering wheel several times. Check the condition of the hoses and connections for leaks.
