Rislone Liquid Aluminium Stop Leak

Use When You Notice…

• Temperature gauge creeping higher in traffic: Engines idling 20–30 minutes in Delhi or Bengaluru traffic lose coolant through micro-leaks — liquid aluminium sealing particles close those paths before serious damage sets in.
• Coolant level dropping with no visible puddle: Internal seeps around gaskets or the heater core lose coolant silently. Sealing particles seek out hidden leak paths and fill them within one to two heat cycles.
• Milky, rusty, or discoloured coolant in the reservoir: Hard Indian tap water accelerates scale and rust buildup, narrowing passages and degrading seals — this formula dissolves deposits and restores flow.
• Coolant topping up has become a routine habit: If you find yourself adding water or coolant every few weeks, a slow internal leak is the likely cause — address it early to avoid engine damage.
• Overheating warning light during monsoon temperature swings: Rapid heat cycling from June to September stresses cooling seals — proactive treatment keeps seals conditioned and leak-free.

Key Benefits

• Overheating Protection: Guards your engine in 45°C+ Indian summer conditions where cooling system failures are the number-one cause of highway breakdowns.
• Leak Sealing: Liquid aluminium repair particles target and permanently fill micro-leaks in radiators, heater cores, and gasket faces without clogging passages.
• Scale and Rust Removal: Dissolves mineral deposits from Indian hard water that narrow coolant passages and reduce heat transfer efficiency.
• Corrosion Inhibition: Protects aluminium radiators and engine water jackets from electrochemical corrosion — especially important in BS6-era engines with more aluminium components.
• Universal Coolant Compatibility: Works with all coolant colours — green, pink, blue, and orange formulations — so no coolant drain is required before use.

The Technology Inside

Rislone Liquid Aluminium Stop Leak combines sub-micron aluminium sealing particles with advanced corrosion inhibitors and scale-dissolving agents in a single, non-clogging formula. The sealing particles remain suspended in the coolant and are drawn to leak sites by pressure differential, depositing and hardening to form a durable seal — a process sometimes called particulate stop-leak technology. Scale dissolvers target calcium and magnesium carbonate deposits — the mineral compounds left behind by hard Indian tap water — freeing up restricted coolant passages without damaging rubber hoses or seals. The corrosion inhibitor package forms a protective film on aluminium and copper surfaces, preventing the electrochemical degradation that shortens radiator life. This multi-action chemistry makes it suitable for the diverse engine cooling architectures found across modern Indian vehicles.

Dosage & Coverage

Add the contents of one bottle directly to the radiator or coolant reservoir as directed on the product label — always to a completely cool engine and never above the maximum coolant level mark. One bottle treats most passenger car and light commercial vehicle cooling systems, which typically hold 4–8 litres of coolant. Allow one to two full heat cycles (cold start to operating temperature and back to cold) for the sealing particles to locate and fill leak paths effectively.

Compatibility

Safe to use with

• All coolant formulations — green OAT, pink HOAT, blue, and orange extended-life types
• Aluminium, copper, brass, and plastic radiator and heater core materials
• Aluminium engine water jackets and thermostat housings
• Rubber and silicone coolant hoses and seals
• Maruti Suzuki, Hyundai, Tata, Honda, Mahindra, Toyota, and Kia cooling systems

Not suitable for

• Does not fix overheating caused by a failed thermostat, worn water pump, or cracked head gasket — these require mechanical repair
• Not a substitute for a full coolant flush when coolant is severely contaminated
• Not recommended for heavy-duty diesel truck cooling systems without confirming label compatibility

Why It Matters in India

Radiator and cooling system failures are among the top causes of roadside breakdowns in India, particularly across Rajasthan, UP, and Maharashtra during April–June when ambient temperatures routinely touch 48°C. Indian vehicles are frequently topped up with untreated municipal tap water, which is high in dissolved minerals that form scale inside radiators and degrade coolant additives faster than in cooler climates. BS6-compliant engines use more aluminium in their cooling circuits than older BS4 units, making corrosion protection more important than ever. Treating minor leaks and deposits early with a liquid aluminium repair product prevents the catastrophic overheating events that cause permanent engine damage — often far from a workshop on a national highway.

How To Use

1. Ensure the engine is completely cool before removing the radiator cap or reservoir cap.
2. Shake the bottle well and pour the contents into the radiator or coolant reservoir.
3. Replace the cap, start the engine, and run it to normal operating temperature.
4. Monitor the coolant level and temperature gauge over the next two heat cycles for improvement.

Safety Note: Never open a radiator cap on a hot engine — pressurised coolant can cause serious scalding burns. If overheating is severe, allow at least 30 minutes of cool-down before inspection.

Frequently Asked Questions

Can I use this with any coolant colour in my Maruti or Hyundai?

Yes — Rislone Liquid Aluminium Stop Leak is compatible with all standard coolant formulations including green, pink, blue, and orange types. There is no need to drain the existing coolant before adding this product, making it a convenient solution for all common Indian passenger vehicles.

Will hard Indian tap water cause problems after I use this?

This product helps dissolve existing scale from hard water, but always use distilled or demineralised water for future top-ups to prevent new deposits forming. Tap water in most Indian cities contains high levels of calcium and magnesium that rapidly form scale inside radiators, undoing the benefits of any treatment product.

Is this product safe for BS6 engines?

Yes — the formula is safe for the aluminium-intensive cooling systems found in modern BS6-compliant engines. Its corrosion inhibitor package is specifically designed to protect aluminium surfaces, which are more prevalent in newer Indian vehicles than in older BS4-era engines.

How often should I use Rislone Liquid Aluminium Stop Leak?

Use it when symptoms appear — rising temperature gauge, dropping coolant levels, or discoloured coolant — or as a preventive treatment at each annual coolant service. For vehicles driven in extreme Indian summer conditions, a preventive dose before the April–June heat season is a worthwhile precaution.

Is Cash on Delivery available, and how quickly will it arrive?

Yes — naredi.in offers Cash on Delivery and free delivery across India, so you can order with confidence without prepayment. Most orders are dispatched within 24–48 hours and delivered to major Indian cities within 3–5 business days.
