3. Інформація про безпеку
- Always allow the engine to cool completely before working on the cooling system to prevent burns from hot coolant or steam.
- Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling coolant and automotive components.
- Охолоджувальна рідина токсична. Уникайте контакту зі шкірою та проковтування. Утилізуйте використану охолоджувальну рідину відповідально відповідно до місцевих правил.
- Переконайтеся, що автомобіль надійно закріплений на домкратах, якщо потрібно його підняти.

4. Монтаж
Installation of a radiator hose typically involves draining the cooling system, removing the old hose, installing the new hose, and refilling the system. If you are not experienced with automotive repairs, it is recommended to seek professional assistance.
Загальні кроки встановлення:
- Приготування: Park the vehicle on a level surface and allow the engine to cool. Place a drain pan under the radiator draincock.
- Злийте охолоджувальну рідину: Open the radiator draincock and remove the radiator cap to allow the coolant to drain completely.
- Зніміть старий шланг: Послабте шланг клampз обох кінців старого шланга радіатора. Обережно поверніть і зняти старий шланг із з'єднань радіатора та двигуна. Будьте готові до залишків охолоджувальної рідини.
- Перевірте підключення: Clean the connection points on the radiator and engine to remove any debris or corrosion.
- Встановлення нового шланга: Вставте новий шлангamps onto the new Continental 66844 hose. Position the new hose onto the radiator and engine connections, ensuring it is fully seated and properly aligned.
- Безпечний клamps: Затягніть шланг клamps securely. Do not overtighten, as this can damage the hose.
- Доливання охолоджувальної рідини: Close the radiator draincock. Refill the cooling system with the manufacturer-recommended coolant mixture.
- Відкачування повітря: 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 purge air from the system. Replace the radiator cap once the system is full and air-free.
- Перевірте наявність витоків: After the engine has cooled, re-check the coolant level and inspect all connections for leaks.

5. Функція та використання
The Continental 66844 Molded Radiator Hose serves as a critical conduit within the vehicle's cooling system. Its primary function is to transport heated coolant from the engine to the radiator for cooling, and then return the cooled fluid to the engine. The molded design ensures a precise fit, preventing kinks and maintaining optimal flow rates. This hose is designed for use with standard automotive coolants and is not suitable for fuel or oil transfer applications.
6. Технічне обслуговування
Regular inspection of your radiator hose is crucial for preventing cooling system failures. Perform visual checks periodically, especially during routine oil changes or other under-hood inspections.
Пункти огляду:
- Cracks and Fissures: Look for any visible cracks, especially near the ends or bends of the hose.
- Hardening or Softening: Squeeze the hose. It should feel firm but pliable. A hose that is excessively hard, brittle, or mushy indicates degradation and requires replacement.
- Bulges or Swelling: Any localized bulges or swelling can indicate internal damage or weakening of the hose structure.
- Витоки: Check for any signs of coolant leakage around the hose clamps or along the hose body. White or colored residue can indicate dried coolant.
- Шланг Clamps: Переконайтесь, що шланг клamps are tight and free from corrosion.
Replace the hose immediately if any signs of wear or damage are observed to prevent potential engine overheating and damage.
7. Вирішення проблем
Common issues related to radiator hoses are typically visual and indicate the need for replacement.
| Симптом | Можлива причина | Дія |
