3. Installation Guide

Proper installation is critical for the performance and safety of your cooling system. If you are unsure about any step, it is recommended to consult a qualified automotive technician.

Safety Precautions:

• Ensure the engine is completely cool before beginning work to avoid burns from hot coolant or engine components.
• Wear appropriate personal protective equipment, including safety glasses and gloves.
• Dispose of old coolant responsibly according to local regulations.
• Do not open the radiator cap when the engine is hot.

Tools Required:

• Pliers or hose clamp removal tool
• Screwdriver (flathead or Phillips, depending on clamp type)
• Drain pan for coolant
• New hose clamps (recommended)
• Coolant (appropriate type for your vehicle)

Installation Steps:

1. Drain Coolant: Place a drain pan under the radiator draincock and open it to drain the coolant. If no draincock is present, carefully remove the lower radiator hose to drain.
2. Remove Old Hose: Loosen the clamps securing the old radiator hose at both ends. Use pliers or a hose clamp tool to slide the clamps away from the connection points. Carefully twist and pull the old hose off the radiator and engine outlets.
3. Clean Connection Points: Inspect the radiator and engine outlets for any debris, corrosion, or old hose residue. Clean these surfaces thoroughly to ensure a good seal with the new hose.
4. Install New Hose: Slide new hose clamps onto the new Continental 66032 hose. Position the hose onto the radiator and engine outlets, ensuring it is fully seated and aligned correctly. The molded shape of the hose is designed for a precise fit.

5. Secure Clamps: Position the hose clamps over the connection points and tighten them securely. Do not overtighten, as this can damage the hose or the connection.
6. Refill Coolant: Close the radiator draincock. Refill the cooling system with the appropriate type and amount of coolant for your vehicle.
7. 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. Squeeze the upper and lower radiator hoses to help release trapped air. Ensure all air is bled from the system.
8. Inspect for Leaks: After the engine has cooled, recheck the coolant level and inspect all connections for any signs of leaks.

4. Operating Principles

The Continental 66032 Molded Radiator Hose is a critical component of your vehicle's engine cooling system. Its primary function is to facilitate the circulation of coolant between the engine and the radiator.

How the Cooling System Works:

• The engine generates heat during operation.
• Coolant, a mixture of antifreeze and water, absorbs this heat as it circulates through the engine block and cylinder head.
• The hot coolant then flows through the upper radiator hose (which the 66032 may be, depending on application) into the radiator.
• Inside the radiator, the coolant is cooled by airflow passing over the radiator fins.
• The cooled coolant then returns to the engine via the lower radiator hose, completing the cycle.
• The molded design of the Continental hose ensures that coolant flow is maintained efficiently, even around tight bends, preventing kinks that could restrict flow and lead to overheating.

5. Maintenance and Care

Regular inspection and proper maintenance will extend the life of your radiator hose and ensure the optimal performance of your vehicle's cooling system.

Inspection Schedule:

• Inspect the radiator hose at least once a year, or during routine vehicle maintenance.
• Check for signs of wear, such as cracks, bulges, softness, hardness, or fraying.
• Look for coolant leaks around the hose connections.
• Ensure hose clamps are secure and not corroded.

Tips for Longevity:

• Maintain the correct coolant level and use the type of coolant recommended by your vehicle manufacturer.
• Address any cooling system issues promptly to prevent excessive heat or pressure that could damage hoses.
• Avoid exposing the hose to petroleum-based products, as it is not designed for fuel or oil transfer and such exposure can degrade the EPDM material.
