Forté Bio Degreaser & Cooling System Flush (J05510)
Effective cooling system cleaning – for better performance and longer engine life
What is it?
Forté Bio Degreaser & Cooling System Flush is an advanced cleaning agent for the cooling system, designed to thoroughly remove all contaminants inside the radiator, heater core, and engine water jacket.
It is a blend of inorganic acids, corrosion inhibitors, and strong cleaning agents that:
- Contains no oil or chlorinated solvents,
- Effectively dissolves oil, sludge, scale, and rust,
- Restores full efficiency of heat exchangers,
- Allows maintaining the proper engine operating temperature,
- Prevents overheating, deposits, and failures.
Why use it?
- Thorough cleaning of the radiator, heater core, and entire cooling system – removes deposits and restores flow even in scaled heater cores without causing leaks.
- Effectively removes oil that has entered the cooling system, e.g., in the event of a head gasket failure.
- Reduces engine operating temperature, thereby extending engine oil life and improving its lubricating properties.
- Eliminates the cause of engine overheating – instead of just removing symptoms.
- Restores full heater core efficiency – especially important in winter.
- Compatible with all glycol-based coolants, including "fill for life" technology and OAT coolants.
- Safe for seals, metals, and aluminium – does not cause any damage to the system.

- Leave at increased RPM for 20–30 minutes.
- Drain the cooling system.
- Thoroughly flush the radiator and water jacket with clean water.
- Refill the system with new coolant.
- For full protection against micro-cracks and rust, we recommend adding Forté Advanced Radiator Stop Leak after flushing.
