Radiator treatments

MOTUL MoCOOL 500ml coolant additive is a unique product that reduces the overall temperature of the cooling system by 15°C. Its unique concentrated formula contains corrosion and rust inhibitors. It radically improvesheat exchange.

WARNING: Does not contain glycol and therefore has no protection against freezing. This product must not be used undiluted!

Dosage for racing circuits:
- Mix 5% MoCool with 95% demineralized or distilled water (when ethylene glycol is prohibited).
Road dosage:
- Mix 5% MoCool with your usual coolant (it's compatible with all ethylene glycol-based coolants including "long life").

Benefits :
- Reduces cooling system temperature by up to 15°C.
- Optimum protection against corrosion and oxidation.
- Water pump protection (prevents cavitation).
- Resistant to high temperatures.
- Recommended for magnesium alloy and aluminum casings, cast-iron blocks and brass, copper and bronze parts.
- Compatible with seals, hoses and plastic components.

Please observe safety precautions.

BY MECACYL 300ml radiator cleaning additive is a top-of-the-range preventive and curative treatment designed to rapidly emulsify and disperse pollutants in the cooling circuit (oils, greases, deposits, etc.). Its de-oiling effect restores optimum operation of the water pump, radiator and thermostat, and restores heat exchange for improved engine cooling. Ideal for completely cleaning thewater circuit following a faulty cylinder head gasket .
What's more, its properties, derived from Mecacyl's hyper-lubricant technology, enable it to protect hoses, temperature sensors and seals to limit the risk of breakdown due to their deterioration.

Dosage : 1 bottle of 300ml for all cooling system capacities.

Advantages :
- Removes oils, greases and pollutants (immediate effect).
- Restores heat exchange.
- Protects all mechanical parts in the cooling circuit.
- Compatible with all types of car and motorcycle engines, aluminum radiators and pumps, cast-iron or alloy engine blocks and all types of coolant (G11, G12, G12 , G12 and G13 included).

Directions for use:
- Drain cooling system completely.
- Close the circuit.
- Shake bottle well.
- Pour the additive into the circuit via the radiator cap.
- Top up with water (volume according to manufacturer's recommendations).
- Start engine.
- Leave to act (engine idling) for 30 minutes.
- Drain the system and rinse thoroughly with clean water before topping up with new coolant.
- To prevent future leaks and seepage, add By Mecacyl stop radiator leak additive (reference UD10241).

Please observe all safety precautions.

BY MECACYL 300ml stop radiator leaks additive is a top-of-the-range preventive and curative treatment designed to quickly and durably plug cooling system leaks and seepage . It restores heat exchange and improves calorstat operation for improved engine cooling. Ideal after using By Mecacyl radiator cleaner (reference UD10240).
In addition, its properties, derived from Mecacyl hyper-lubricant technology, provide long-term protection against seizure of heating valves and prevent greasy deposits in the circuit (particularly on temperature sensors).

INFORMATION: Greasy deposits are produced by tiny oil vapors passing through the seals. These deposits clog the circuit and, above all, the temperature sensor that controls the fan's start-up and shut-down. As the fan is calibrated to operate at a precise temperature, the result is a rise in cooling system temperature (during city traffic or at idle) and the risk of cylinder head deformation, leading to costly breakdowns.

Dosage : 1 bottle of 300ml for all cooling circuit capacities.

Advantages :
- Curative use (eliminates leaks and seepage with immediate effect).
- Restores heat exchange.
- Preventive use possible in a clean circuit, on a new vehicle or after a repair.
- Provides long-term protection against future breakdowns.
- Compatible with all types of car and motorcycle engine, aluminum radiators and pumps, cast-iron or alloy engine blocks and all types of coolant (G11, G12, G12 , G12 , and G13 included).

Directions for use :
- Shake the bottle well and pour the additive into the circuit via the radiator cap.
- Start engine.
- Switch on the heating system.
- Allow engine to idle for a few minutes, with immediate effect.
- Final results after a few tens of minutes.

Please observe all safety precautions.

METAL 5radiator anti-leak 300ml is a preventive and curative treatment designed to plug leaks and ensure perfect sealing of the cooling circuit. It works with all types of coolant, while respecting hoses, seals and metals.

Its specific formula combats micro-leaks without clogging the pipes, restoring the cooling system's original performance.

Dosage: 1 bottle of 300ml treats circuits containing up to 12L of coolant.

Advantages :
- Easy to use.
- Restores radiator and seal tightness.
- Prevents engine overheating.
- Extends radiator life.
- Resists heat and vibration.
