Additive MOTUL RADIATOR STOP LEAK 300ML

MOTUL RADIATOR STOP LEAK is designed for use in all cooling circuits of all types of petrol and diesel engines, naturally aspirated or turbocharged, with or without catalytic converters, using all types of fuel. MOTUL RADIATOR STOP LEAK effectively seals critical microcracks and small leaks. It works quickly and easily in all closed liquid cooling systems.

MOTUL RADIATOR STOP LEAK can be used to seal water coolers and heat intercoolers, leaking water pumps, valves, loose connections and cracked coolant hoses without clogging the cooling system. Recommended for use in passenger vehicles, commercial vehicles, etc., and industrial heat exchangers.

Can be used in curative or preventive mode as well.

Compatible with all types of coolants (inorganic, hybrid, lobrid and OAT).

Provides perfect lubrication during the sealing process of the cooling circuit.

MOTUL RADIATOR STOP LEAK, added to the engine cooling circuit, allows:

• Covering critical microcracks and small leaks without clogging the cooling system.
• Improving the performance of valves, thermostats and water pumps.
• Lowering the engine temperature.

1. Check the coolant level.
2. Add MOTUL RADIATOR STOP LEAK and start the engine to warm up the coolant in the cooling system.
3. Move all vehicle heating controls to the ‘hot’ position.
4. Let the engine idle for approx. 10 minutes.
5. Check the coolant level again and see if the leaks have been eliminated.

Warning: Open the radiator cap slowly and gradually - pressurised installation - risk of burns! 300 ml is sufficient for cooling systems with a capacity of 12 L. Do not exceed the recommended ratio.
