Rislone Radiator 10-Minute Flush 355ml

Use When You Notice…

• Temperature gauge creeping higher in traffic or summer heat — scale and rust restrict coolant flow; this car radiator flush cleaner clears those restrictions in 10 minutes.
• Brown or discoloured coolant in the reservoir — rust contamination reduces heat transfer; flushing restores proper cooling before engine damage occurs.
• Coolant level dropping slowly with no visible external leak — mineral deposits stress internal seals; flushing removes the root cause early.
• Cooling system repeatedly topped up with tap water — Indian hard water accelerates scale buildup inside passages, and a flush is the fastest corrective step.
• Engine running warmer than usual after monsoon season — temperature swings stress seals and loosen rust; flush before winter to start fresh.

Key Benefits

• Rapid 10-minute action: Dissolves years of scale and rust buildup in a single short engine run — no overnight soak needed.
• Overheating protection: Restores full coolant circulation so your engine stays safe in 45°C+ Indian summer conditions.
• Hard-water deposit removal: Targets the calcium and mineral scale that Indian tap water leaves inside radiator tubes and water jackets.
• Aluminium-safe formula: This aluminium radiator cleaner uses non-acidic chemistry that protects modern alloy components found in BS6 engines.
• Universal coolant compatibility: Works safely alongside all OEM-specified coolants without gel formation or chemical conflict.

The Technology Inside

Rislone Radiator 10-Minute Flush uses a blend of surfactants, chelating agents and corrosion inhibitors to break down oxide scale, calcium carbonate deposits and ferrous rust particles that cling to coolant passages. The chelating agents surround and lift mineral ions — the same mechanism used in industrial descaling — without attacking the base metal of aluminium, copper or plastic components. A wetting-agent package lowers surface tension inside narrow radiator tubes, flushing loosened debris into suspension so it drains completely when you flush the system. Corrosion inhibitors then leave a protective film on metal surfaces, slowing fresh rust formation between service intervals. This chemistry is why it qualifies as the best radiator flush for diesel engines and petrol engines alike — the formula is fuel-type agnostic.

Dosage & Coverage

One 355 ml bottle treats a standard passenger-car cooling system of 4–8 litres — covering most Maruti Suzuki, Hyundai and Tata models sold in India. Add the product to a cool radiator or reservoir, run the engine for 10 minutes at idle, then drain and refill with fresh coolant and distilled water. Repeat annually or whenever coolant appears discoloured — more frequently if your vehicle operates daily in heavy city traffic.

Compatibility

Safe to use with

• All coolant colours and formulations — green, pink, blue and orange OAT/HOAT coolants
• Aluminium, copper, brass and plastic radiators and engine water jackets
• Petrol, diesel and CNG-powered BS6 vehicles from all major Indian OEMs
• Compatible with Maruti Suzuki, Hyundai, Tata, Honda and Mahindra cooling systems

Not suitable for

• Does not fix overheating caused by a failed thermostat, faulty water pump or blown head gasket — those require mechanical repair
• Not a coolant replacement — always refill with the correct coolant after flushing

Why It Matters in India

Radiator failures are among the top causes of roadside breakdowns in India, particularly during April–June when ambient temperatures in Rajasthan, UP and Maharashtra regularly cross 45°C. Indian tap water used for topping up is often hard water, depositing calcium and magnesium scale that narrows coolant passages over time. For vehicles running in Delhi, Mumbai or Bengaluru traffic — where engines idle for 20–30 minutes continuously — a clean, free-flowing cooling system is not optional, it is survival. Using this car radiator cleaner once a year keeps high-mileage Indian vehicles protected through every season, from summer to monsoon.

How To Use

1. Ensure the engine is completely cool before opening the radiator cap or coolant reservoir.
2. Pour the entire 355 ml bottle into the radiator or coolant reservoir without exceeding the maximum level mark.
3. Start the engine and allow it to idle for 10 minutes with the heater set to maximum.
4. Drain the cooling system fully, flush with clean water, then refill with fresh coolant and distilled water.

Safety Note: Never open a hot radiator cap — allow the engine to cool for at least 30 minutes. Dispose of drained coolant responsibly; do not pour into drains or open ground.

Frequently Asked Questions

Can I use this with any coolant colour in my BS6 car?

Yes — Rislone 10-Minute Flush is compatible with all standard coolant formulations including green, pink, blue and orange. It is safe for every BS6 vehicle sold by major Indian OEMs without voiding coolant compatibility.

Will hard Indian tap water cause problems after flushing?

After flushing, always refill with distilled or demineralised water mixed with the correct coolant. Using tap water again will restart scale buildup — distilled water is available at most Indian petrol stations and auto-parts shops for very low cost.

Is this the best radiator flush for diesel engines like the Innova or Scorpio?

Yes — the formula is fuel-type agnostic and works equally well in high-displacement diesel engines. It is particularly valuable for commercial-use diesel vehicles that idle frequently and accumulate scale faster than petrol cars.

How often should I use a radiator flush in Indian conditions?

Once a year is the general recommendation — ideally before summer (March) or after monsoon (October). Vehicles driven daily in heavy city traffic or filled repeatedly with tap water may benefit from flushing every six months.
