Product Description

RAVENOL Professional Radiator Stop Leak is a dispersion for protecting the cooling system and the combustion chamber against leaks and increasing operational safety. It permanently seals hairline cracks and leaks and prevents seals from sweating, thus eliminating any coolant loss. RAVENOL Professional Radiator Stop Leak is suitable for closed cooling systems.

Technical Characteristics and Features: 

  • Protection against sweating cylinder head gaskets
  • Seals hairline cracks and leaks in the cooling system

Application Notes:

RAVENOL Professional Radiator Stop Leak is added to the radiator. If there are filters in the cooling system, a radiator jointing material may not be used.

Areas of Application:

  • Severe sweating of cylinder head gaskets
  • Leaky hose connections
  • Hairline cracks in the radiator, cylinder head, or engine block

Instructions: RAVENOL Professional Radiator Stop Leak suffices for 10 liters or about 3 gallons of coolant.

Open the heating valve completely. The engine should be at operating temperature. Shake the can and fill the content into the cooling system with the engine running. Add coolant. After filling, allow the engine to continue to run for at least 10 min. or take a test drive. Check the system’s coolant level, absence of air, and leak tightness.

For semi truck radiators the maximum mix ratio is: 1:100

RAVENOL Professional Radiator Stop Leak is also suitable for closed cooling systems.

Quality Classifications:

RAVENOL Professional Radiator Stop Leak is completely compatible with anti-freeze agents and coolants. RAVENOL Professional Radiator Stop Leak is neutral to rubber, synthetic materials, light alloys, and non-ferrous metals.
