Imoto Radiator Stop Leak 300ml – Cooling System Leak Sealer

Imoto Radiator Stop Leak (300ml) – Cooling System Leak Sealer

Seal pinhole leaks, hairline radiator cracks, and weeping gaskets fast with Imoto Radiator Stop Leak (300ml). Engineered as an emergency repair fluid and protective preventative additive across South Africa, this advanced formula circulates freely through vehicle cooling systems to seal coolant leaks without clogging narrow radiator channels or heater core matrix tubes.

Fast Emergency Leak Sealing Without Dismantling

Coolant leaks lead to rapid engine overheating, lost pressure, and severe internal thermal damage. Imoto Radiator Stop Leak contains micro-sealing fibers and active sealing particles that seek out oxygen and pressure differentials at leak points. Upon reaching hairline cracks or weeping hose fittings, the particles interlock to form a permanent, heat-resistant seal that stops fluid loss instantly.

Prevents Corrosion & Lubricates Water Pump Seals

In addition to sealing active leaks, Imoto Radiator Stop Leak provides ongoing anti-corrosion protection for aluminum, cast iron, and copper cooling components. It contains active lubricant additives that condition water pump seals, preventing shaft squeaks and extending water pump bearing life.

Safe for Modern Aluminum & Synthetic Cooling Systems

• Safe for All Metals: 100% compatible with aluminum, brass, copper, and cast iron blocks and radiators.

• Hose & Gasket Protection: Will not degrade rubber coolant hoses, silicone gaskets, or plastic radiator tanks.

• Universal Coolant Safety: Mixes safely with all standard green, red, yellow, and blue OAT/IAT coolants and anti-freeze liquids.

Key Performance Features

• Fast-Acting Leak Sealer: Permanently seals hairline cracks, pinholes, and weeping radiator seams.

• No Clogging Guaranteed: Micro-particle formulation flows freely without clogging radiator channels or heater cores.

• Protects & Lubricates: Conditions water pump seals and guards metal surfaces against rust and scale.

• Multi-Part Cross-Reference: Matches industry part codes BL, CH328L, CH431L, M3590500, and SH205.

• Convenient 300ml Bottle: Single-dose bottle size treats standard passenger car and light commercial cooling systems.

Recommended Application Guidelines

1. Allow the engine to cool completely before removing the radiator cap or expansion tank cap.

2. Shake the 300ml Imoto Radiator Stop Leak bottle vigorously to suspend sealing particles evenly.

3. Pour the entire bottle into the radiator or expansion tank.

4. Top up with coolant if necessary, replace the cap, and turn on the vehicle's interior heater to maximum hot.

5. Start the engine and idle or drive the vehicle for 10 to 15 minutes to allow the sealer to circulate and cure at leak sites.

Mechanic's Tip: Keep a bottle of Imoto Radiator Stop Leak in your vehicle boot or glovebox as part of your emergency roadside toolkit to prevent getting stranded by sudden coolant leaks!
