VAICO V20-1280 Radiator Hose

VAICO V20-1280 Radiator Hose

The VAICO V20-1280 Radiator Hose is a high‑performance cooling system component designed to deliver reliable heat transfer and durability in automotive applications. Crafted from premium materials, this hose meets the stringent demands of modern engines while offering ease of installation and long‑term reliability.

Key Features & Specifications

• Material: High‑grade silicone reinforced with a durable rubber core to resist heat, pressure, and chemical degradation.
• Diameter: 20 mm inner diameter, ensuring optimal coolant flow for most mid‑size engines.
• Length: 1280 mm (1.28 m) – a standard length that fits a wide range of vehicle models without the need for custom cutting.
• Pressure Rating: Up to 8 bar, suitable for high‑pressure cooling systems found in performance and heavy‑duty vehicles.
• Temperature Range: Operates effectively from –40 °C to +120 °C, accommodating extreme climates and engine operating conditions.

Compatibility & Vehicle Applications

The V20-1280 is engineered for a broad spectrum of vehicles, particularly those in the BMW 5‑Series lineup. It is fully compatible with:

• BMW E60, E61, E63, and E64 models (2003–2010)
• BMW 5 Touring (E61) from 2004 to 2010
• Other mid‑size sedans and touring cars that use a 20 mm upper radiator hose specification.

Because of its standardized dimensions, the hose can be swapped into many other makes and models with similar cooling system layouts, making it an excellent choice for aftermarket replacements or performance upgrades.

Installation Guide

1. Preparation: Drain the coolant system completely to avoid pressure buildup. Remove the old hose by loosening the clamps and carefully detaching the hose ends from the radiator and water pump.
2. Cleaning: Clean the connection points on both the radiator and the water pump with a soft brush or compressed air to remove debris and ensure a tight seal.
3. Mounting: Slide the new V20-1280 hose onto the radiator outlet, ensuring that it sits flush against the fitting. Repeat for the water pump side.
4. Securing: Tighten the clamps evenly to avoid uneven pressure points that could lead to leaks or hose damage.
5. Re‑filling: Refill the cooling system with fresh coolant, then bleed air from the system according to the vehicle’s service manual. Check for any signs of leakage before starting the engine.

Performance Benefits

• Enhanced Heat Transfer: The silicone outer layer reduces thermal resistance, allowing coolant to flow more efficiently and keep engine temperatures within optimal ranges.
• Extended Lifespan: Resistance to UV radiation, ozone, and chemical attack means the hose remains flexible and intact for many years, even under high‑temperature operation.
• Improved Reliability: The robust construction minimizes the risk of burst or leakage, which can lead to engine overheating and costly repairs.
• Easy Maintenance: Standardized size and fittings mean that replacement is straightforward for mechanics and DIY enthusiasts alike.
