Regular inspection of rubber and plastic hoses in your vehicle's engine, accessory, and emission systems is essential due to the high temperatures under the hood, which can lead to material deterioration. Look out for cracks, loose clamps, hardening, and leaks in these hoses. Ensure that clamped hoses haven't lost tension, potentially causing leaks. When dealing with vacuum hoses, which may be color-coded, ensure that replacement hoses are of the same material. To thoroughly check hoses, they may need to be removed from the vehicle, so label hoses and fittings for proper reinstallation. Pay attention to plastic T-fittings for cracks, and inspect the fitting and hose where they connect for distortion. You can use a small piece of vacuum hose as a stethoscope to detect vacuum leaks by listening for hissing sounds while probing around hoses and fittings. When working with fuel hoses, be prepared to catch spilled fuel, as they are usually under pressure. Check for deterioration, chafing, and cracks, especially at bends and near fittings. Use hose designed for your fuel injection system when replacing fuel hoses. For fuel lines, some use quick-connect fittings requiring special tools for disconnection, while metal lines should be inspected for bends, crimps, and cracks. When replacing metal fuel lines, opt for seamless steel tubing for strength. Finally, inspect metal brake lines for cracks and loose fittings, especially at the master cylinder and brake proportioning unit, and address any brake fluid leaks promptly with a thorough brake system inspection.
