1. Introduction
The Continental 66018 Molded Radiator Hose is engineered for optimal performance within a vehicle's cooling system. Its primary function is to facilitate the transfer of glycol-based coolants to and from the radiator, as well as through other essential components of the coolant system. This hose is specifically molded to ensure full flow even through tight bends, simplifying installation and reducing stress on radiator connections.
This manual provides comprehensive information regarding the product's features, installation guidelines, operational characteristics, maintenance recommendations, and technical specifications to ensure proper use and longevity of your Continental radiator hose.

3. Setup and Installation
Proper installation is crucial for the performance and longevity of your radiator hose. It is recommended that installation be performed by a qualified automotive technician. If you choose to install it yourself, ensure you have the necessary tools and follow all safety precautions.
General Installation Steps:
- Safety First: Ensure the engine is cool and the vehicle is safely supported. Disconnect the battery's negative terminal.
- Drain Coolant: Place a drain pan under the radiator and open the drain cock to drain the coolant.
- Remove Old Hose: Loosen the hose clamps at both ends of the old radiator hose. Carefully twist and pull the old hose off the connections. Be prepared for residual coolant.
- Inspect Connections: Clean the connection points on the radiator and engine block/thermostat housing. Ensure they are free of debris, corrosion, or old hose residue.
- Install New Hose: Slide new hose clamps onto the new Continental 66018 hose. Position the new hose onto the connections, ensuring it is fully seated.
- Secure Clamps: Tighten the hose clamps securely, but do not overtighten, as this can damage the hose or connections.
- Refill Coolant: Close the radiator drain cock. Refill the cooling system with the appropriate coolant mixture as specified by your vehicle manufacturer.
- Bleed Air: Start the engine and allow it to reach operating temperature with the heater on full. Monitor the coolant level and add more as needed to bleed air from the system. Check for leaks.
Important: Always confirm that the hose fits your specific year, make, and model of vehicle before installation. Original configurations are available to ensure proper fit and function.
4. Operating Characteristics
The Continental 66018 Molded Radiator Hose is designed to operate effectively within a wide temperature range and is integral to maintaining your vehicle's engine temperature.
Temperature Range:
- Minimum Operating Temperature: -40°F (-40°C)
- Maximum Operating Temperature: 275°F (135°C)
Caution: This hose is specifically designed for coolant transfer applications. It is not for use in fuel or oil transfer applications, as this can lead to product failure and potential damage to your vehicle.
5. Maintenance
Regular inspection of your radiator hose is essential for preventing cooling system failures and ensuring the longevity of your vehicle's engine. While the Continental 66018 hose is resistant to Electrochemical Degradation (ECR), routine checks are still recommended.
Maintenance Tips:
- Visual Inspection: Periodically check the hose for signs of wear, such as cracks, bulges, leaks, or hardening. A healthy hose should feel firm but pliable.
- Hose Clamps: Ensure hose clamps are tight and free from corrosion. Loose clamps can lead to leaks.
- Coolant Level and Quality: Regularly check your coolant level and ensure it is clean and at the correct concentration. Contaminated or old coolant can accelerate hose degradation.
- System Pressure: Ensure your cooling system maintains proper pressure. A faulty radiator cap or leaks elsewhere can affect hose performance.
Replace the hose immediately if any signs of damage or excessive wear are observed to prevent engine overheating and potential damage.
6. Troubleshooting
If you experience issues with your vehicle's cooling system after installing or while using the Continental 66018 Molded Radiator Hose, consider the following common troubleshooting points:
Common Issues and Solutions:
- Coolant Leakage:
- Check Clamps: Ensure hose clamps are properly tightened.
- Inspect Hose: Look for cuts, punctures, or cracks in the hose itself.
- Connection Points: Verify that the hose is fully seated on the radiator and engine connections.
- Hose Collapse/Softness:
- This can indicate a vacuum in the cooling system, often due to a faulty radiator cap or a blockage. Inspect the radiator cap and ensure proper coolant flow.
- Hose Hardening/Cracking:
- This is a sign of aging or chemical degradation. Replace the hose immediately.
- Engine Overheating:
- While a faulty hose can contribute, overheating often points to broader cooling system issues (e.g., thermostat, water pump, radiator, fan). Consult a professional technician for diagnosis.
If issues persist after basic troubleshooting, it is highly recommended to seek assistance from a certified automotive mechanic.
