Wurth Radiator Flush & Cooling System Cleaner (250ml)

Maintain optimum engine cooling efficiency and peak operational reliability with the Wurth Radiator Flush & Cleaner (250ml). Over time, your vehicle's cooling circuit accumulates rust, limescale, mineral deposits, and oily residues caused by breakdown or component wear. These blockages isolate heat transfer, leading to engine overheating and potential gasket failures. This premium German formulation is specifically engineered to dissolve, loosen, and safely flush away stubborn contaminants from the entire cooling matrix.

This advanced flushing treatment is completely neutral to metallic alloys, rubber components, and plastic parts used within modern radiator systems. By restoring unrestricted coolant flow through the water jackets and radiator cores, it safeguards your engine against thermal stress and ensures stable operating temperatures during demanding driving conditions.

Key Product Features & Performance Benefits:

• Cleans the Entire Cooling Circuit: Thoroughly dislodges and flushes out lime, scale, rust, and sludge deposits accumulated inside the radiator and engine block.
• Dissolves Oil & Grease Contaminants: Efficiently binds and emulsifies oily residues caused by cylinder head or oil cooler leaks, ensuring a clean system.
• Prevents Engine Overheating: Restores factory-level heat dissipation across the radiator core to keep the engine operating within optimal temperature ranges.
• Component and Seals Safe: Highly safe formulation that does not degrade or affect radiator metals, plastic tanks, water pump seals, or rubber hoses.
• Universal Engine Application: Perfectly safe and highly recommended for use in all Petrol, Diesel, and LPG vehicle cooling systems before adding fresh coolant.

3. Turn the vehicle cabin heater control to maximum, start the engine, and let it idle at normal operating temperature for approximately 30 minutes.
4. Switch off the engine, let it cool slightly, and completely drain out the flushing liquid along with all the dislodged deposits.
5. Flush the system briefly with fresh water to clear any remaining loose debris, then refill the system with fresh radiator coolant mixed as per manufacturer guidelines.
