PENNZOIL RADIATOR COOLANT
A concentrated premium quality, ethylene glycol-based coolant formulated to help protect cooling system metals such as solder, copper, brass, steel, cast iron, and aluminum throughout the year. It is silicate-free, helping reduce the risk of issues associated with unstable silicate gel formation or silicate drop-out in automotive and light-duty gasoline applications. The formulation also excludes nitrites, borates, and amines, supporting a cleaner and moving environmentally considerate coolant choice.
High water purity due to removal of dissolved solids
Prevents freeze-up in winter and boil-over in summer
Provides protection from rust and corrosion
Compatible with all other major brands of antifreeze; will not affect automotive hoses and gaskets

Recommended for use in a wide range of automotive and light-duty engine cooling systems that require an ethylene-glycol–based coolant. It can be used during routine coolant replacement, system top-up, or when preparing a proper coolant mixture after maintenance work on the cooling system. For optimum performance, the coolant concentration in the radiator should be maintained at a minimum of 33%, prepared by mixing the concentrate with clean water. This helps ensure the cooling system continues to function within its intended operating range. As part of regular vehicle care, periodically check the coolant level and condition, especially after extended driving or seasonal temperature changes, and replenish with the correctly mixed coolant when necessary.
