Liqui Moly | Motorbike Radiator Stop Leak - 125mL

Liqui Moly Motorbike Radiator Stop Leak 125mL (Kühler Dichter) is a highly specialized, premium-grade technical cooling system additive engineered explicitly for motorcycles and powersports applications. Formulated to circulate fluidly with the engine's coolant, this advanced German treatment is designed to target, react with, and permanently seal hairline cracks and micro-leaks caused by stone impacts, vibration stress, or minor corrosion. Activating instantly upon contact with external air at the leak source, it creates a durable and heat-resistant seal, effectively preventing critical coolant loss and protecting the engine from catastrophic thermal spikes without creating internal flow restrictions.

Product Specifications:

• Brand: Liqui Moly

• Product Line: Motorbike Dedicated Series

• Product Type: Radiator and Cooling Circuit Leak Repair Additive (Kühler Dichter)

• Volume: 125 mL

• Country of Origin: Germany 

Key Features & Performance:

• Instantaneous Micro-Leak Sealing: Rapidly seals hairline cracks, pinholes, and weeping joints in the cooling circuit under active operating pressures.

• Guaranteed Safe on Flow Passages: Advanced chemical composition ensures localized reaction at the leak point only, guaranteeing that narrow radiator cores and water jackets remain completely unblocked.

• Aluminum and Polymer Neutral: Fully compatible and safe for use with modern lightweight aluminum radiators, plastic end tanks, and elastomeric coolant hoses.

• Safeguards Powertrain Integrity: Prevents catastrophic engine overheating by maintaining optimal cooling fluid levels, avoiding costly head gasket structural failures.

• Cost-Efficient Maintenance: Provides an immediate, field-proven remedy that eliminates the costly need for immediate radiator teardown or full hardware replacement.

Usage Instructions:

• Ensure the motorcycle engine is entirely cold; never attempt to loosen or open the radiator cap while the cooling system is hot or pressurized.

• Shake the 125mL Liqui Moly canister thoroughly to guarantee absolute distribution of the active sealing particulates.

• Open the radiator cap (or the expansion/overflow reservoir) and pour the entire contents of the bottle directly into the coolant mix.

• Securely re-fasten the radiator cap.

• Start the ignition and let the engine idle continuously, or take the motorcycle for a smooth ride for at least 10 to 15 minutes to allow the thermostat to open, circulating the additive to seal the leak.

• One 125mL canister is optimally calibrated to treat cooling systems containing up to 5 liters of coolant fluid.

Suitability & Applications:

• Universally engineered for all liquid-cooled motorcycles, scooters, sports bikes, and ATVs; completely compatible with all standard, organic, and synthetic antifreeze formulations and coolants.

Note:

This formulation is strictly designed for the preventative upkeep and therapeutic sealing of minor hairline micro-cracks; it cannot remedy physical macro-failures, such as large structural ruptures in plastic end tanks, completely blown coolant hoses, or heavily failed water pump mechanical seals. Never introduce this additive into the engine oil crankcase or the fuel delivery system.
