Cooling System Cleaner

Cleans the radiator and prolongs the life of the cooling system.

The Problem

Vehicle cooling systems work by transferring heat from the engine to the radiator where it can be dissipated. Over time, deposits throughout the system slow the rate of heat transfer in the radiator, while reducing the efficiency of the heater core, water pump, and thermostat. Over time, this can cause overheating, reduced efficiency, and serious damage to the system’s components.

The Solution

BARDAHL PRO® Cooling System Cleaner is a very effective cleaner that removes damaging deposits of rust, scale, and sludge. This special formula includes wetting and surface active agents that protect the radiator and promote better heat transfer and coolant flow, which restores the efficiency and performance of the cooling system. It is safe for all cooling system components and can be used in both gasoline and diesel engines and works with all types of coolant.


  • Cleans and conditions the entire cooling system.
  • Removes harmful rust, scale, and sludge deposits.
  • Safe for use in aluminum radiators and will not harm plastic components.
  • Restores heat transfer efficiency to prevent over-heating and costly engine damage.
  • Safe for all types of coolant and anti-freeze solutions.


Install cleaner into the radiator or pressurized reservoir. Run the vehicle until the engine is heated and the thermostat has opened. Exchange fluid with a professional service machine, or drain the system by removing the radiator drain valve or removing the lower coolant hose. Refill system with properly mixed anti-freeze. Recommend service every 30,000 miles. Dispose of any used or unused solution in accordance with local, state, and federal regulations.
