A reservoir hose is exposed to engine-bay heat and to power steering fluid over time. The following signs suggest this hose may need replacing:

• Fluid seeping at the hose or at its connections.
• A cracked, swollen or softened hose.
• A fluid level that keeps dropping.

If this hose is the source of the leak, the Sunsong 3404943 replaces it. After installation, refill and bleed the system as directed by the vehicle's service information.
