Liqui Moly | Pro-Line Radiator Stop Leak K - 250mL

Liqui Moly Pro-Line Radiator Stop Leak K is a professional-grade, high-performance chemical sealant formulated to immediately arrest coolant loss within automotive cooling systems. Secured in a technical metal canister highlighting the premium blue-and-black "PRO-LINE" badge and globally recognized this formula utilizes specialized micro-solid polymers to target and mend leaking cooling structures.

Specifications:

• Brand: Liqui Moly.

• Series: Pro-Line.

• Product Type: Radiator Stop Leak / Cooling System Sealant.

• Volume: 250mL.

• Country of Origin: Germany.

Benefits:

• Instant Pinhole & Crack Mitigation: Rapidly localizes and completely seals hair-thin fissures, porous weld spots, and stone-strike punctures in the radiator core.

• Absolute System Safety Guarantee: Formulated to only react and cure at the leak site exposed to air, ensuring zero risk of clogging water pumps, heater cores, or narrow fluid channels.

• Universal Coolant Compatibility: Blends seamlessly and safely with all conventional ethylene glycol anti-freeze solutions and modern organic acid technology (OAT) coolants.

• Protects Seals and Gaskets: Contains dedicated stabilization additives that preserve the structural flexibility of internal rubber hoses, seals, and plastic side-tanks.

• Highly Cost-Efficient Emergency Repair: Eliminates the urgent financial necessity for total radiator replacement in the event of minor micro-leaks, saving labor hours.

How to Use:

1. Shake the 250mL Liqui Moly Pro-Line canister thoroughly to ensure all sedimented sealing particles are fully suspended.

2. Start the vehicle and allow the engine to idle until the thermostat opens and the cooling loop becomes warm.

3. Turn off the engine and carefully unscrew the radiator pressure cap (exercise extreme caution to avoid hot coolant spray).

4. Pour the entire contents directly into the radiator filler neck (not the plastic expansion tank) and secure the cap back tightly.

5. Restart the engine and keep it running or drive the car normally for 10 to 15 minutes to allow the compound to circulate and cure at the leak zone.

6. One single 250mL can is sufficient to treat up to 4 liters of total coolant volume.

Suitable For:

• All aluminum, copper, and composite plastic radiators across passenger vehicles, commercial trucks, and stationary power plants running on petrol or diesel.

Note:

• This technical treatment is intended for structural micro-fissures; large physical splits, ruptured hoses, or cracked metal pipes require physical mechanical substitution.
