Justice Brothers RC-22P Super Radiator Cooler is a high-performance radiator additive that improves heat transfer, reduces cylinder head temperatures, and helps prevent overheating in diesel and gasoline cooling systems—ideal for heavy-duty towing, high ambient heat, and work-truck uptime for peak fleet performance. It is compatible with all antifreezes, inhibits rust and acid formation, and prevents foaming to protect radiators, water pumps, and cooling passages under severe use.
Enhances coolant wetting and heat transfer to shed heat faster, lowering cylinder head temperatures under load and at sustained RPM.
Helps prevent overheating in severe duty, including towing, hauling, and high ambient temperature operation common to diesel trucks.
Protects the system by inhibiting rust and acid formation while preventing foaming for consistent coolant contact and pump efficiency.
Compatible with all antifreezes and cooling system metals for broad platform coverage across modern diesel pickups.
Reduces cylinder head temperatures by improving radiator-side heat transfer characteristics during sustained load.
Prevents foaming to maintain stable coolant flow and heat exchange at high RPM and grade.
A must for air-conditioned vehicles where condenser heat adds to cooling system load, especially in hot climates.
Trusted additive within Justice Brothers’ Radiator System Products line alongside cleaners and protectants.
Diesel pickups used for towing, hauling, and commercial duty where thermal margin is critical to reliability.
Compatible with gasoline and diesel engines across automotive, agricultural, and heavy equipment segments for mixed fleets.
RC-22P is provided in a 14 oz bottle for heavy equipment and severe-duty use cases.
Use rate: add 1 quart of Super Radiator Cooler per 20 quarts of coolant/water mixture; check system capacity before dosing. (1 quart = 32 oz)
For a 20-quart system, add 1 quart; scale proportionally for larger or smaller systems and avoid overfilling the expansion space.
Always follow the cooling system manufacturer’s capacity guidance and ensure proper bleed/vent procedures after service.
With the engine cool, shake well and pour the calculated amount directly into the radiator or degas/expansion tank, then top off with coolant as needed.
Run the engine to operating temperature with the heater on high to circulate and burp air; recheck coolant level when cool and top off if necessary.
Compatible with ethylene glycol and propylene glycol antifreezes and standard corrosion-inhibitor formulations.
