Rislone 41196

Use When You Notice…

• Coolant level drops gradually with no obvious large leak: A silent internal weep drains your system — this car radiator leak sealer deposits a seal precisely where pressure is escaping.
• Damp or white crusty patches under the front of the car: Mineral-rich Indian tap water leaves scale marks as coolant seeps — seal the source before it becomes a costly failure.
• Heater output has turned lukewarm: A slow heater core weep reduces hot coolant flow to the cabin — sealing it early avoids an expensive heater core replacement.
• Temperature gauge creeping up in stop-start city traffic: Even tiny coolant loss dramatically cuts cooling capacity during long Mumbai or Delhi commutes — especially in 42–48°C Indian summers.
• Radiator fins show minor stone-chip damage: Road debris on Indian highways causes tiny coolant weeps that worsen over time — early treatment prevents a full overheating event.

Key Benefits

• Fast-Acting Seal: Closes small leaks within 15–30 minutes of normal engine running — no draining, no disassembly.
• Universal Coolant Compatibility: Works with all coolant colours and formulations, including modern OAT and HOAT types used in BS6 vehicles.
• Non-Clogging Formula: Fine sealing particles are engineered to deposit only at leak points, leaving water pump bearings and healthy passages completely unaffected.
• Overheating Prevention: Restores proper coolant volume and pressure, protecting engines in Indian summer heat of 42–48°C ambient temperature.
• Rejuvenates Aging Engines: Trusted by Indian mechanics to restore high-mileage Maruti, Hyundai and Tata cooling systems without costly workshop repairs.

The Technology Inside

Rislone 41196 uses a suspension of fine reactive particles — formulated at a specific particle-size threshold — that circulate freely through the entire cooling circuit. When these particles encounter a leak point, the localised drop in fluid pressure and velocity causes them to react and form a stable, heat-resistant seal. This targeted deposition mechanism, sometimes called selective precipitation sealing, means healthy metal surfaces, coolant passages and water pump impeller clearances are never affected. The formula also contains corrosion inhibitors and conditioners that help maintain coolant chemistry, extending cooling system life in the high-dust, high-heat conditions typical of Indian driving.

Dosage & Coverage

One 325 ml bottle of Rislone 41196 treats a typical Indian passenger car cooling system — including systems on Maruti Swift, Hyundai i20, Tata Nexon and similar vehicles — as per label guidance. Add to a cool radiator or expansion tank, run the engine for 15–30 minutes including idle time, then top up coolant level if required. For ongoing protection, the product may remain in the system permanently between regular coolant service intervals.

Compatibility

Safe to use with

• All coolant colours — green, pink, blue and orange
• Aluminium, copper, brass and plastic radiators
• All OAT, HOAT and conventional coolant types including BS6-compliant formulations
• Petrol and diesel passenger cars, SUVs and light commercial vehicles

Not suitable for

• Large cracks, split hoses or severely corroded radiators — physical repair or replacement required
• External hose joints or clamp failures
• Heavy-duty commercial truck cooling systems requiring commercial-grade sealants

Why It Matters in India

Indian roads throw stones and debris that chip radiator fins and cause tiny coolant weeps that are easy to ignore until overheating strikes. Speed breaker impacts stress heater core connections, while 42–48°C May–June ambient temperatures mean even a small coolant loss leads to rapid thermal overload — particularly in stop-start traffic on Delhi's Ring Road or Mumbai's Western Express Highway. Indian vehicle owners typically keep cars for 10–15 years, and aging cooling systems on high-mileage Maruti, Hyundai and Tata models benefit enormously from a proactive best radiator sealant treatment that extends service life without a full workshop overhaul.

How To Use

1. Ensure the engine is cool, then remove the radiator cap or expansion tank cap carefully.
2. Shake the bottle well and pour the entire contents directly into the radiator or expansion tank.
3. Replace the cap, start the engine and run for 15–30 minutes, including some idle time, to allow full circulation and sealing.
4. After the sealing cycle, check coolant level and top up with compatible coolant if needed.

Safety Note: Never open a radiator cap on a hot engine — wait until fully cool to avoid scalding from pressurised coolant.

Frequently Asked Questions

Will this clog my heater core or water pump?

No — the sealing particles are sized to deposit only at actual leak points where fluid velocity and pressure drop significantly. They pass freely through healthy passages and water pump clearances without any build-up.

Can I leave Rislone 41196 in the system permanently?

Yes — it is safe to leave in as a long-term protective measure and will not degrade coolant chemistry or corrosion inhibitors. Simply treat it as part of your regular coolant and change at normal service intervals.

Is it safe for BS6-compliant vehicles like the Tata Nexon or Hyundai Creta?

Yes — the formula is compatible with modern OAT and HOAT coolants used in all BS6 petrol and diesel vehicles. It contains no chlorides or harsh solvents that could affect modern aluminium engine components.

How do I know the leak has been sealed?

After the 15–30 minute run cycle, the coolant level should stabilise and the damp patches or dripping under the car should stop. If the temperature gauge returns to normal and coolant level holds steady over subsequent days, the seal is working.

Is Cash on Delivery available and how quickly will it be delivered?

Yes — naredi.in offers Cash on Delivery (COD) and free delivery across India. Most orders reach metro cities within 3–5 business days; Tier 2 and Tier 3 cities within 5–7 business days.
