    5-in-1 Radiator Stopper Leak 310ml

    5in1 Radiator Stop Leak is a coolant additive for petrol and diesel engines, specially developed for G12 and G12+ coolants, which permanently seals radiator leaks. Simple hairline cracks in the radiator are often overlooked during maintenance. These hairline cracks can cause a leak in the long term. A leak is detected by the 5in1 Radiator Stop Leak and filled with sealing components.

    1. The new formula is good for 30 liters of coolant.
    2. Suitable for petrol and diesel engines
    3. Effective repair of radiator leaks
    4. Stops and prevents leaks
    5. Radiator leak stop protects the cooling system
    6. Added corrosion inhibitors
    7. Radiator leak stopper helps prevent blockages
    8. Suitable for all types of coolant and antifreeze

    User manual
    Suitable for all aluminium, plastic, and steel radiators of cooling systems in petrol, diesel, and LPG engines. Compatible with water, coolants, and conventional antifreeze. Not suitable for cooling circuits with a built-in filter unit. Shake very well before use. Add the contents of the can to the slightly warm (but NOT hot!) cooling system with the engine switched off.

    It is recommended to pour the contents directly into the radiator. If the radiator is a closed system, the contents can also be poured into the coolant expansion reservoir. After adding, seal the cooling system properly, start the engine and let it run for 10 minutes, or drive a short distance with the heating system switched on.

    Important: be careful when opening the radiator or the cooling system: hot coolant or steam may escape from the system! Contaminated cooling systems must first be cleaned with TecLub Radiator Cleaner.

    A 310 ml bottle is sufficient for cooling systems with a capacity of up to 12 liters.

      Minimal leakage in the radiator, but with 5in1 the radiator is sealed again. Excellent result. Recommended.
