High-Performance Radiator Flush & System Restorer

SPG Cooling System Cleaner is a professional-grade, fast-acting formulation engineered to clean and restore optimal thermal efficiency within automotive cooling systems. It helps remove rust, sludge, scale, oil residues, scum, and calcareous lime deposits.

Suitable for light and heavy-duty petrol and diesel engines, this cleaner helps neutralize residual acids, protect internal metal and rubber components, reduce localized overheating, and support long-term engine performance.

Key Features & Benefits

• Advanced Sludge Dispersion: Rapidly disintegrates and suspends rust, sludge, and hard-water lime scaling inside radiator cores and engine jackets.
• Oil & Grease Counteraction: Helps break down greasy coatings and combustion byproducts that may contaminate the coolant flow path.
• Acid Neutralization: Acts against harmful acid conditions caused by degraded glycol anti-freeze solutions.
• Material Neutral Integrity: Formulated without aggressive mineral acids or harsh caustics, making it safe for rubber hoses, gaskets, O-rings, and cooling system plastics.
• Universal Compatibility: Compatible with conventional and modern extended-life OAT/HOAT anti-freeze mixtures and cooling fluids.

Application & Usage Directions

Safety Precaution: Never open the cooling system cap or add fluids while the engine is hot. Allow the engine and cooling system pressure to cool down fully before servicing.

1. System Drainage: Make sure the engine is completely cold, then drain the old or contaminated coolant from the system.
2. Chemical Introduction: Close all drain ports securely, shake the can gently, and pour the full 300 ml content into the radiator neck or expansion reservoir. Top off the system with clean water.
3. Thermal Cycling: Reinstall the pressure cap, set the cabin heater to hot, start the engine, and let it idle at normal operating temperature for 10 minutes.
4. Flushing Protocol: Turn off the engine, allow a short cool-down period, then drain the cleaner-water mixture and flush with clean water until the discharge runs clear.
5. Final Refilling: Refill the cooling system with the recommended anti-freeze and water mixture or pre-blended premium coolant.
6. Reservoir Maintenance: If the vehicle has an overflow or expansion tank, rinse it thoroughly and refill to the correct level.
