Rislone Liquid Aluminium Stop Leak

Use When You Notice…

• Temperature gauge climbing in traffic: Engines idling 20–30 minutes in Delhi or Mumbai jams overheat fast — this liquid stop leak restores proper heat transfer quickly.
• Coolant level dropping with no visible external leak: A slow internal seep is often the culprit; sealing it early prevents costly head gasket damage.
• White residue or scale inside the reservoir cap: A clear sign that hard Indian tap water has deposited minerals — this product dissolves that stubborn buildup.
• Coolant looking rusty or brown-coloured: Rust particles circulating through the system accelerate wear; the aluminium-safe formula neutralises corrosion at the source.
• Monsoon temperature swings stressing seals: Rapid heat cycling during June–September weakens rubber hoses and gaskets — regular treatment keeps seals pliable and leak-free.

Key Benefits

• Overheating Protection: Maintains safe coolant temperatures even when ambient heat crosses 45°C during Indian summer months.
• Leak Sealing: Seals minor radiator and water jacket leaks progressively over one to two heat cycles without workshop visits.
• Scale and Deposit Removal: Removes scale and rust deposits caused by Indian hard water, restoring full coolant flow through blocked passages.
• Corrosion Inhibition: Protects aluminium, copper and brass components from electrochemical corrosion common in mixed-metal Indian cooling systems.
• Universal Coolant Compatibility: Works with all OEM-specified coolant colours — no costly flush needed before adding.

The Technology Inside

Rislone Liquid Aluminium Stop Leak uses a blend of organic acid technology (OAT) corrosion inhibitors, proprietary sealing particles and scale-dissolving surfactants that target the root causes of cooling system failure in Indian vehicles. The sealing particles are sized to plug micro-fractures and pinhole leaks in radiator cores and water jackets without blocking coolant passages or the heater matrix. Wetting agents reduce surface tension inside the coolant circuit, improving heat transfer efficiency — critical when coolant temperatures spike during prolonged idling on congested Indian highways. The formula is phosphate-free and safe for the aluminium-heavy engine architecture of modern BS6-compliant engines, where traditional inorganic inhibitors can cause pitting and deposit formation over time.

Dosage & Coverage

Add one bottle directly to the coolant reservoir or radiator as per label instructions — always to a completely cool engine and never exceeding the maximum level mark. A single bottle treats most passenger car and light commercial vehicle cooling systems found in India, typically ranging from 4 to 8 litres of total capacity. The product works progressively over one to two heat cycles; check coolant level and temperature behaviour after your next two drives.

Compatibility

Safe to use with

• All coolant colours — green, pink, blue and orange OAT and HOAT formulations
• Aluminium, copper, brass and plastic radiator cores and tanks
• Rubber hoses, thermostat housings and water pump seals
• BS6 and BS4 petrol and diesel engines in passenger cars and SUVs
• Maruti Suzuki, Hyundai, Tata, Honda, Mahindra, Toyota and Kia cooling systems

Not suitable for

• Does not fix overheating caused by a failed thermostat, faulty water pump or blown head gasket — these require mechanical repair
• Not a permanent replacement for a cracked radiator or severely corroded cooling system
• Not intended for heavy commercial diesel engines above 3.5 tonnes GVW

Why It Matters in India

Radiator and cooling system failures are among the top causes of roadside breakdowns in India, particularly across Rajasthan, UP, MP and Maharashtra during May and June when road surface temperatures exceed 55°C. Indian vehicles frequently accumulate scale faster than European counterparts because tap water — high in calcium and magnesium — is routinely used to top up radiators at roadside dhabas and petrol stations. Addressing minor leaks and scale buildup early with a trusted radiator repair liquid prevents the overheating events that cause permanent engine damage hundreds of kilometres from the nearest authorised service centre. This product is an essential part of any preventive maintenance kit for the Indian vehicle owner.

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 directly into the coolant reservoir.
3. Replace the cap securely, start the engine and allow it to reach normal operating temperature.
4. Check coolant level and temperature gauge behaviour after the next two to three heat cycles.

Safety Note: Never open a radiator cap on a hot engine — pressurised coolant can cause severe burns. If your temperature gauge is in the red, pull over safely, switch off the engine and wait at least 30 minutes before inspecting.

Frequently Asked Questions

Can I use this with any coolant colour already in my system?

Yes — Rislone cooling products are compatible with all standard coolant formulations including green, pink, blue and orange. There is no need to drain your existing coolant before adding this product.

Will hard Indian tap water cause problems after using this?

The product will dissolve existing scale caused by hard water, but always use distilled or demineralised water for future top-ups to prevent new deposits from forming. Tap water reintroduces minerals that counteract the inhibitor package over time.

Is this safe for my BS6 Maruti Suzuki or Hyundai engine?

Yes — the phosphate-free, aluminium-safe formula is specifically compatible with modern BS6 engine cooling systems. It will not damage light-alloy cylinder heads, aluminium radiators or the plastic components used in contemporary Indian vehicles.

How often should I use this product?

Use it as a treatment when symptoms appear or as a preventive measure at every second coolant service interval, typically every 40,000–50,000 km. In Indian conditions — extreme heat, hard water, stop-and-go traffic — annual treatment is a sensible precaution.

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

Yes — COD is available on all orders across India through naredi.in. Most metro and Tier-1 city deliveries arrive within 2–4 business days; Tier-2 and Tier-3 locations typically receive orders within 4–7 business days.
