Nulon Radiator Flush & Clean (R40) is a non-acidic radiator and cooling system cleaner that effectively cleans in one simple 20-minute operation. Many similar products have to be left in the cooling system for several days, which creates the risk of the user either forgetting or extending the drain and flush time for reasons of convenience. The results can be detrimental and cause expensive, long-term damage to the cooling system and associated components. Nulon R40 overcomes this potential risk as the whole cleaning process is completed in one simple operation.
- Use R40 as a complete cooling system flush to remove insulating built-up sludge and residue before changing coolant in any cooling system. This procedure will ensure optimum heat transfer and efficiency of the entire cooling system.
- Whenever draining a cooling system, or changing brands of coolant, it is always recommended to clean the system with R40.
- Use R40 before removing a radiator from a vehicle for reconditioning. Clean the entire system with R40 so when the radiator is reinstalled, the core will not be contaminated with scale and residue from the rest of the system.
