Rislone Liquid Aluminium Stop Leak

Use When You Notice…

• Temperature gauge creeping higher in traffic: Engines idling 20–30 minutes in Bengaluru or Mumbai jams lose coolant through micro-leaks — 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 — this liquid stop leak formula seeks hidden leak paths and fills them within one to two heat cycles.
• Rusty or discoloured coolant in the reservoir: Hard Indian tap water accelerates scale and rust buildup, narrowing passages and reducing flow — the scale-dissolving agents restore circulation without flushing.
• Radiator repeatedly topped up with tap water: Untreated water leaves mineral deposits that corrode aluminium components — liquid aluminium inhibitors coat and protect vulnerable surfaces.
• Seasonal overheating during April–June: Ambient temperatures above 45°C reduce cooling system headroom dramatically — adding this product restores the margin your engine needs to stay safe.

Key Benefits

• Overheating Protection: Protects against overheating in 45°C+ Indian summer conditions, reducing the risk of head gasket failure and warped cylinder heads.
• Leak Sealing: Liquid aluminium particles permanently seal micro-leaks in radiators, heater cores, and water jacket seams without blocking narrow coolant passages.
• Scale and Rust Removal: Removes scale and rust deposits caused by Indian hard water, restoring full coolant flow and improving heat transfer efficiency.
• Aluminium Corrosion Defence: Corrosion inhibitors form a protective layer on aluminium radiator fins and engine water jackets, extending component life.
• Universal Coolant Compatibility: Safe with all OEM-specified coolant formulations — no colour mixing issues, no chemical incompatibility risk.

The Technology Inside

Rislone Liquid Aluminium Stop Leak combines suspended metallic sealing particles with organic acid technology (OAT) corrosion inhibitors specifically chosen for compatibility with modern aluminium and plastic cooling components. The sealing particles remain inert in free-flowing coolant but activate under pressure and heat at a leak point, bonding to form a durable seal without blocking coolant passages. A secondary package of scale dissolvers attacks calcium and magnesium carbonate deposits — the exact mineral compounds left by hard Indian tap water — breaking them loose so they can be carried out during a subsequent flush. Wetting agents lower coolant surface tension, improving heat transfer across radiator cores that may have suffered partial blockage. The result is a cooling system that runs measurably cooler, holds its level longer, and resists the corrosion cycle that shortens radiator life in India's humid monsoon climate.

Dosage & Coverage

Add one bottle directly to the coolant reservoir or radiator as directed on the label — always with the engine completely cool and never above the maximum fill mark. One bottle treats a standard passenger car cooling system of 4–8 litres capacity, covering most Maruti Suzuki, Hyundai, Tata, Honda, and Mahindra models. Allow one to two full heat cycles for sealing particles to locate and seal active leak paths, then check coolant level and temperature gauge behaviour.

Compatibility

Safe to use with

• All coolant colours and formulations — green (IAT), pink, blue, and orange (OAT/HOAT)
• Aluminium, copper, brass, and plastic radiators and engine water jackets
• Maruti Suzuki, Hyundai, Tata, Honda, Mahindra, Toyota, and Kia cooling systems
• Petrol, diesel, and CNG engines including BS6-compliant vehicles

Not suitable for

• Mechanical failures — thermostat failure, water pump failure, or blown head gasket require workshop repair
• Large physical cracks or splits in the radiator body — these need professional replacement
• Engines already running at dangerously high temperatures — cool the engine fully before adding any product

Why It Matters in India

Radiator and cooling system failures are among the top causes of roadside breakdowns on Indian highways, particularly in north and central India between April and June when ambient temperatures regularly exceed 45°C. BS6 engines run at tighter tolerances and are more sensitive to coolant condition than older BS4 units, making proactive cooling system maintenance more important than ever. Indian stop-and-go city traffic prevents the airflow that keeps radiators efficient at highway speeds, meaning even a small leak or partial blockage can push coolant temperatures into the danger zone within minutes. Addressing minor leaks and scale early with a liquid aluminium radiator sealant costs a fraction of the head gasket or radiator replacement that follows if overheating goes unchecked.

How To Use

1. Park on level ground and allow the engine to cool completely — at least two hours after last use.
2. Open the coolant reservoir cap slowly and confirm the level is below the maximum mark.
3. Pour the entire bottle into the reservoir or radiator as directed on the product label.
4. Replace the cap, start the engine, and monitor the temperature gauge over the next two to three heat cycles.

Safety Note: Never open a radiator or reservoir cap on a hot engine — scalding coolant can eject under pressure and cause serious burns. If the temperature gauge is in the red, pull over safely and wait for the engine to cool before inspecting.

Frequently Asked Questions

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

Yes — Rislone Liquid Aluminium Stop Leak is compatible with all standard coolant formulations including green IAT, orange OAT, and pink or blue HOAT types. There is no need to drain your existing coolant before adding this product, saving you time and money.

Is this safe for my BS6 Maruti Suzuki or Hyundai?

Yes. The formula is safe for all BS6-compliant petrol and diesel engines, which use aluminium-intensive cooling systems that benefit from the corrosion inhibitors in this product. Always follow the dosage on the label to avoid exceeding the recommended concentration.

Will Indian tap water cause problems after I use this?

This product helps dissolve existing hard-water scale deposits, but using tap water for future top-ups will continue adding new mineral deposits. Always top up with distilled or demineralised water — available at most Indian pharmacies and auto parts shops — to keep the cooling system clean long-term.

How often should I use a liquid stop leak treatment?

Use it when symptoms appear — rising temperature gauge, slow coolant loss, or discoloured coolant — or as a preventive measure at the start of every summer season. For high-mileage vehicles or those operating in extreme heat, a preventive dose before April is a sound practice.
