Radiator Anti-Rust

Removes Rust and Lubricates the Pump to Eliminate Noise.

The Problem

Over time a vehicle’s cooling system will gradually build-up deposits of rust, scale, and sludge. This can reduce the efficiency of the cooling system and lead to radiator failure or other costly repairs.

The Solution

BARDAHL Radiator Anti-Rust & Water Pump Lubricant is an easy to use chemical solution that works while the engine is running. The solution removes and prevents rust, corrosion and sludge deposits. It also lubricates the water pump, bearings and seals, which eliminates noise caused by dry bearings and extends the life of the cooling system components.


  • Removes and inhibits rust and corrosion from forming in the radiator and cooling system
  • Lubricates the water pump bearings and seals to improve its operation
  • Restores reserve alkalinity to the coolant
  • Helps control thermal degradation of coolant
  • Safe for all coolant and anti-freeze solutions



Remove the radiator cap when the engine is cool and use a rag for protection. FOR NORMAL USE: Make sure the coolant level is 3 inches below the top of the overflow pipe and that the hose is clear. Add the entire contents, replace the cap, and run the engine for at 15 minutes to circulate the solution. FOR EXTREME CASES: If the radiator is in poor condition; drain and flush the unit, fill with clear water and add the entire contents. Replace the cap and run the engine for 15 minutes. Allow the radiator to cool, Drain the system by opening the radiator petcock or carefully removing lower radiator hose. Flush the system with clear water. Close all drains and refill the radiator with coolant or a water anti-freeze mixture. Dispose of any used or unused solution in accordance with the local, state and federal regulations.
