Product Description
The GATES Radiator hose (3474) is an original-equipment-quality flexible coolant line engineered by GATES. Positioned within the engine bay cooling circuit, its primary function is to transport high-temperature coolant between the engine block/thermostat housing and the radiator core. Constructed with an electrochemically resistant EPDM rubber body, it is structurally reinforced with a high-tensile aramid knit layer. This prevents structural wall swelling, flattening under heavy vacuum loads, and degradation from localized oil spills or extreme thermodynamic cycles.

Vehicle Compatibility
This 32mm internal-bore molded coolant line is configured specifically for early-generation, water-cooled Volkswagen Group (VAG) passenger cars utilizing small-to-mid displacement naturally aspirated engine layouts from the late 1970s through the early 1990s:
| Car Model | Compatible Engines / Variants | Engine Power (hp / kW) | Year of Manufacture |
|---|---|---|---|
| VW Golf I (17) / Jetta I (16) | 1.5 / 1.6 / 1.6 GTI / 1.8 / 1.8 GTI (Carburettor and early K-Jetronic fuel injection models) |
70 - 112 hp / 51 - 82 kW | 1977 - 1983 |
| VW Golf I Convertible (155) | 1.5 / 1.6 / 1.8 (Classic Karmann-built configurations) | 70 - 112 hp / 51 - 82 kW | 1979 - 1993 |
| VW Scirocco I & II (53, 53B) | 1.5 / 1.6 / 1.6 GTI / 1.8 / 1.8 GTI | 70 - 112 hp / 51 - 82 kW | 1977 - 1992 |
| VW Caddy I Pickup (14) | 1.5 / 1.6 / 1.8 Petrol variants | 75 - 95 hp / 55 - 70 kW | 1982 - 1992 |
⚠️ Technical Routing Advisory: Coolant plumbing paths across classic A1-chassis VAG platforms varied fundamentally depending on whether the vehicle featured a narrow core radiator (430mm) with an integrated expansion bottle or a wider cross-flow radiator paired with an external bulkhead expansion tank. Always map the precise bends and branch ports of your existing hose before final installation to verify that this 32mm GATES molded geometry perfectly aligns with your specific thermostat flange and radiator end-tank layout.
