1. Introduction
The Continental 49293 Accu-Drive Tensioner Assembly is engineered to provide optimal belt tension, enhancing the efficiency and longevity of your vehicle's drive system. This assembly features advanced torsion-spring technology, which offers superior corrosion protection compared to traditional flat-spring designs. It is designed to meet or exceed original equipment manufacturer (OEM) specifications for fit and performance, ensuring reliable operation and extended belt life.
2. Safety Information
Always prioritize safety when working with automotive components. Failure to follow these guidelines may result in injury or damage to the vehicle.
- Personal Protective Equipment (PPE): Always wear safety glasses, gloves, and appropriate clothing to protect against potential hazards such as moving parts, hot surfaces, and sharp edges.
- Vehicle Stability: Ensure the vehicle is securely supported on jack stands or a lift before beginning any work. Never rely solely on a jack.
- Engine Off: Always ensure the engine is turned off and the ignition key is removed before working on the belt drive system. Disconnect the battery's negative terminal to prevent accidental starting.
- Hot Components: Engine components can remain hot for an extended period after operation. Allow sufficient time for the engine to cool before handling parts.
- Pinch Points: Be aware of potential pinch points around belts and pulleys. Keep hands and fingers clear of moving parts.
- Proper Tools: Use only the correct tools for the job. Using improper tools can damage components or cause injury.
- Professional Assistance: If you are unsure about any step of the installation or maintenance process, consult a qualified automotive technician.

4. Setup & Installation
Installation of the Continental 49293 Accu-Drive Tensioner Assembly requires basic automotive tools and adherence to proper safety procedures. Refer to your vehicle's service manual for specific torque specifications and detailed routing diagrams for the serpentine belt.
Tools Required:
- Socket Wrench Set
- Torque Wrench
- Tensioner Release Tool (if applicable for your vehicle)
- Gloves and Safety Glasses
Installation Steps:
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and turn off the engine. Disconnect the negative terminal of the battery.
- Locate the Tensioner: Identify the existing belt tensioner. It is typically located on the front of the engine, part of the serpentine belt system.
- Relieve Belt Tension: Using a tensioner release tool or appropriate wrench, rotate the tensioner arm to relieve tension on the serpentine belt. Carefully remove the belt from the tensioner pulley.
- Remove Old Tensioner: Unbolt the old tensioner assembly from its mounting points on the engine. Note the orientation and any shims or spacers.
- Inspect Mounting Surface: Clean the mounting surface on the engine to ensure proper seating of the new tensioner.
- Install New Tensioner: Position the new Continental 49293 Accu-Drive Tensioner Assembly onto the mounting points. Install the bolts and tighten them to the vehicle manufacturer's specified torque. Do not overtighten.
- Reinstall Serpentine Belt: Refer to your vehicle's belt routing diagram. Carefully route the serpentine belt over all pulleys, ensuring it is correctly seated in all grooves. Use the tensioner release tool to rotate the tensioner arm and slide the belt onto the tensioner pulley.
- Verify Belt Routing: Double-check that the belt is correctly routed and seated on all pulleys.
- Reconnect Battery: Reconnect the negative terminal of the battery.
- Test Operation: Start the engine and observe the belt and tensioner for proper operation. Listen for any unusual noises.
5. Maintenance
The Continental 49293 Accu-Drive Tensioner Assembly is designed for long-term, maintenance-free operation. However, periodic inspection of the entire serpentine belt system is recommended as part of your vehicle's routine maintenance schedule.
Inspection Guidelines:
- Visual Inspection: Regularly inspect the tensioner pulley for signs of wear, cracks, or damage. Check the tensioner arm for proper movement and ensure it is not seized or excessively loose.
- Belt Condition: Examine the serpentine belt for cracks, fraying, glazing, or missing ribs. Replace the belt if any signs of wear are present.
- Noise Check: Listen for any squealing, chirping, or grinding noises coming from the tensioner or belt system, especially during engine startup or acceleration. These noises can indicate a failing tensioner or worn belt.
- Tension Check: While the engine is off, observe the tensioner's position. It should maintain consistent tension on the belt. Excessive vibration or flapping of the belt during engine operation may indicate a failing tensioner.
If any issues are detected during inspection, it is recommended to replace the tensioner assembly to prevent further damage to the belt system or other engine components.
6. Troubleshooting
This section provides solutions to common issues you might encounter with your Accu-Drive Tensioner Assembly.
| Symptom | Possible Cause | Solution |
|---|---|---|
| Squealing or Chirping Noise from Belt | Worn or misaligned belt, failing tensioner pulley bearing, insufficient belt tension. | Inspect belt for wear and proper alignment. Check tensioner pulley for smooth rotation. Replace tensioner if pulley bearing is noisy or seized. |
| Belt Slippage | Insufficient tension from tensioner, worn belt, contaminated belt/pulleys. | Verify tensioner operation. Replace belt if worn. Clean any oil or fluid contamination from belt and pulleys. |
| Excessive Belt Vibration/Flapping | Failing tensioner spring or damper, worn tensioner pivot. | Replace the tensioner assembly. |
| Grinding Noise from Tensioner | Failing tensioner pulley bearing. | Replace the tensioner assembly. |
If troubleshooting steps do not resolve the issue, it is recommended to seek professional automotive service.
