3. Setup and Installation
Proper installation of the AGS BL512 line is crucial for safety and performance. This product is intended for professional installation or by individuals with significant automotive repair experience.
3.1 Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands or a lift before working underneath.
- Disconnect the vehicle's battery if working near electrical components.
- Be aware of hot engine components and exhaust systems.
- Handle brake fluid, fuel, and transmission fluid with care, as they can be corrosive or flammable. Dispose of fluids properly.
3.2 Required Tools and Materials
- Line wrenches or flare nut wrenches (to prevent rounding off fittings)
- Tubing bender (if custom bends are required)
- Tubing cutter (if custom length is required)
- Flaring tool (if custom flares are required)
- Brake fluid, transmission fluid, or fuel (as applicable)
- Drain pans and rags
3.3 Installation Steps (General)
- Preparation: Identify the old line to be replaced. Clean the surrounding area to prevent contamination.
- Removal: Carefully disconnect the old line from its fittings. Be prepared for fluid leakage. Note the routing of the original line.
- Forming (if necessary): If the new line needs to be bent to match the original routing, use a tubing bender to create smooth, gradual bends. Avoid kinking the line.
- Installation: Route the new AGS BL512 line in the same path as the original. Secure it with appropriate clips or fasteners.
- Connection: Connect the ends of the new line to the corresponding fittings. Hand-tighten first, then use a line wrench to tighten securely, but do not overtighten.
- Fluid System Specifics:
- Brake Lines: After installation, bleed the brake system thoroughly to remove all air. Check for leaks.
- Fuel Lines: Check all connections for leaks before starting the engine.
- Transmission Lines: Refill transmission fluid to the correct level and check for leaks.
- Final Inspection: Double-check all connections for tightness and ensure the line is not rubbing against any moving parts or sharp edges.
4. Operating Considerations
Once installed, the AGS BL512 line operates as an integral part of your vehicle's fluid transfer system. Its function is passive, ensuring the safe and efficient flow of brake fluid, fuel, or transmission fluid as intended by the vehicle manufacturer.
No direct user operation is required for the line itself after proper installation and system bleeding/filling. The line is designed to withstand the pressures and temperatures typical of its intended automotive applications.
5. Maintenance
The AGS BL512 steel line is a durable component designed for long service life. Regular inspection is recommended as part of routine vehicle maintenance to ensure continued safety and performance.
5.1 Inspection Schedule
- Inspect the line during routine oil changes or other under-vehicle inspections.
- Check immediately if you notice any signs of fluid leaks, spongy brakes, or unusual odors (like fuel).
5.2 What to Look For
- Leaks: Any visible fluid weeping or dripping around the line or its connections.
- Corrosion: Significant rust or corrosion on the line, especially in areas exposed to road salt or moisture.
- Damage: Kinks, dents, cracks, or abrasions on the line.
- Loose Connections: Ensure all fittings are tight and secure.
If any issues are detected, it is critical to address them promptly. A compromised brake, fuel, or transmission line can lead to serious safety hazards or vehicle damage. Replacement of the affected line is typically the recommended course of action.
6. Troubleshooting
Troubleshooting issues related to the AGS BL512 line primarily involves identifying and addressing leaks or blockages. Given its passive role, most problems stem from improper installation or physical damage.
6.1 Common Issues and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Fluid Leak at Connection | Loose fitting, damaged flare, cross-threaded connection | Tighten fitting (do not overtighten). If leak persists, inspect flare and fitting for damage. Replace line or fitting if damaged. Ensure correct threading. |
| Fluid Leak Along Line | Corrosion, physical damage (kink, crack, abrasion) | Replace the damaged section of the line or the entire line. |
| Restricted Fluid Flow (e.g., weak brakes, fuel starvation) | Kinked line, internal blockage (rare for new lines) | Inspect the line for kinks. If kinked, replace. If blockage is suspected, flush or replace the line. |
For any persistent or severe issues, it is highly recommended to consult a qualified automotive technician.
