Product Description
The ORIGINAL IMPERIUM Radiator hose (220391) is an original-equipment-quality molded coolant delivery line engineered by Original Imperium. Positioned at the bottom configuration of the engine bay, its primary operational purpose is to bridge the gap between the lower outlet of the engine radiator and the cooling loop inlet at the mechanical water pump. It provides a flexible yet highly durable conduit that channels chilled coolant back into the engine block to absorb combustion chamber heat. Because radiator hoses are subjected to severe internal cooling system pressures, constant vibration from engine movement, and rapid temperature shifts from freezing to boiling, original factory hoses eventually experience internal fabric reinforcement failure, soft spots, bloating, or splits near the attachment clamps. This premium replacement restores robust, leak-free fluid transfer to safeguard against critical coolant loss.

Vehicle Compatibility
This lower radiator molded hose configuration is a standard cooling circuit profile engineered to fit early water-cooled Volkswagen Group (VAG) passenger cars and light utilities from the 1970s through the 1990s, as well as selected classic Daewoo applications:
| Car Model / Platform | Compatible Engines / Variants | Engine Displacement Range | Year of Manufacture |
|---|---|---|---|
| VW Golf II (19E, 1G1) / Jetta II (19E) | 1.6 / 1.8 / 1.8 GTI / 1.6 D / 1.6 TD (Standard lower radiator loop setups) |
1595 - 1781 cc | 1983 - 1992 |
| VW Golf I (17) / Jetta I (16) / Golf 1 Convertible (155) | 1.5 / 1.6 / 1.6 GTI / 1.8 / 1.8 GTI / 1.5 D / 1.6 D | 1471 - 1781 cc | 1974 - 1993 |
| VW Caddy I (14) / Scirocco I & II (53, 53B) | Standard petrol and diesel overhead cam powerplants | 1.5 / 1.6 / 1.8 / 1.6 D | 1974 - 1992 |
| Daewoo Lanos (KLAT) / Nubira (KLAJ) / Saloon / Hatchback | Selected 16V overhead-cam petrol variants | 1.6 16V | 1997 - 2003 |
⚠️ Cooling System Hose Profile Fitment Warning: Within the Volkswagen Golf MK2 and MK1 platforms, lower radiator hoses vary drastically depending on whether the vehicle was factory-equipped with an integrated oil cooler, a larger hot-climate radiator option, or manual vs. automatic transmissions. This hose features a **length of 222mm with stepped 31mm and 34mm internal diameters**. Always physically measure your existing hose layout before ordering. When replacing a lower hose, never reuse old, corroded spring-tension hose clamps; installing fresh, high-quality stainless steel worm-drive or constant-tension clamps is highly recommended to prevent premature leaks at the radiator plastic neck flange.
