3. Pautes d'instal·lació
Proper installation is crucial for the performance and longevity of your radiator hose. If you are unsure about any step, it is recommended to consult a qualified automotive technician.
3.1 Precaucions de seguretat
- Ensure the engine is cool before beginning any work on the cooling system.
- Utilitzeu equips de protecció individual adequats, inclosos guants i protecció ocular.
- Be aware that coolant can be toxic; handle with care and dispose of properly.
- Refer to your vehicle's service manual for specific instructions and torque specifications.
3.2 Passos d'instal·lació
- Drenatge del refrigerant: Place a suitable drain pan under the radiator and open the drain cock to drain the coolant.
- Treure la mànega vella: Afluixeu la mànega clamps at both ends of the old radiator hose. Carefully twist and pull the old hose off the radiator and engine connections.
- Inspeccionar connexions: Clean any residue or corrosion from the radiator and engine hose connections. Inspect for damage.
- Instal·leu una mànega nova: Feu lliscar el nou precinte de la mànegaamps onto the new Continental 62803 hose. Position the new hose onto the radiator and engine connections, ensuring it is fully seated and aligned correctly.
- Assegureu-vos Clamps: Apretar la mànega clamps securely, but do not overtighten, as this can damage the hose or connections.
- Recàrrega de refrigerant: Close the radiator drain cock. Refill the cooling system with the manufacturer-recommended coolant.
- Purgar aire: Start the engine and allow it to reach operating temperature with the heater on high. Monitor the coolant level and add more as needed to remove any trapped air from the system.
- Comproveu si hi ha fuites: After the engine has cooled, recheck the coolant level and inspect all connections for leaks.

4. Funcionament i Funció
Once installed, the Continental 62803 Molded Radiator Hose operates as a critical component of your vehicle's cooling system. It forms a sealed pathway for coolant to circulate between the engine and the radiator. The hose's EPDM construction and synthetic reinforcement allow it to withstand the high temperatures and pressures inherent in an automotive cooling system, ensuring consistent coolant flow and preventing leaks.
The molded shape is specifically designed to accommodate the contours of the engine bay, preventing kinking and ensuring an unrestricted flow of coolant, which is vital for maintaining the engine's optimal operating temperature.
5. Manteniment i cura
Regular inspection and proper care can extend the life of your radiator hose and prevent cooling system failures.
5.1 Calendari d'inspecció
- Inspect the hose every 12,000 miles or 12 months, whichever comes first.
- Check for signs of wear, such as cracks, bulges, hardening, softening, or leaks around the clamps.
- Assegureu-vos que la mànega estigui ben tancadaampsón ajustats i lliures de corrosió.
5.2 Atenció general
- Maintain the correct coolant level and use the recommended type of coolant for your vehicle.
- Address any cooling system issues promptly to prevent excessive pressure or temperature fluctuations that can stress hoses.
- Avoid exposing the hose to petroleum-based products, as it is not designed for fuel or oil transfer applications.
