- Use a wrench to loosen the clamp and pull the hose off.
Remove the mounting bolts securing the power steering pump to the engine.
Carefully detach the pump from the engine.
Install the new power steering pump.
- Torque the mounting bolts to the manufacturer's specifications (refer to service manual for exact torque values).
Reconnect the return hose and ensure it is secure.

4. Inspect and Replace Power Steering Hoses

Inspect the power steering hoses for cracks, leaks, or damage.
If any hoses are damaged, remove them using a wrench to loosen the clamps.
Install new hoses, ensuring they are routed correctly and securely fastened.
Check for proper fitment and clearance from moving parts.
