Peak PKA0B3 Premixed Antifreeze Coolant 1 Gallon

Product Description

The PEAK PKA0B3 is a conventional premixed antifreeze and coolant formulated with ethylene glycol and conventional inhibitors. It comes ready to use in a 1-gallon container and requires no dilution before installation. The green-colored formula is engineered to protect cooling system components against freezing, boiling, and corrosion. With a freezing point of 0 degrees F and a boiling point of 317 degrees F, this coolant maintains system integrity across a wide operating range. It is appropriate for use by fleet technicians, diesel mechanics, and experienced service professionals working on older or heavy-use vehicles.

The PKA0B3 is suited for diesel engines, light- to medium-duty trucks, and older gasoline-powered cars that require a conventional green coolant formula. It is not formulated for OAT or HOAT-spec systems. This product is typically used during cooling system flushes, radiator replacements, or top-off service on vehicles that call for a standard ethylene glycol-based coolant with conventional inhibitor chemistry. The 1-gallon size is practical for single-vehicle service or small top-off jobs.

Key Features

• Conventional premixed formula — no dilution required before use
• Ethylene glycol base with conventional corrosion inhibitors
• Freezing point of 0 degrees F (-18 degrees C) for cold-weather protection
• Boiling point of 317 degrees F (158 degrees C) for high-temp system stability
• Flash point of 241 degrees F (116 degrees C)
• Green liquid appearance for easy identification and system compatibility verification

Compatibility

Designed for diesel engines, light- to medium-duty trucks, and older cars requiring a conventional green ethylene glycol antifreeze and coolant. Not intended for systems specified for OAT, HOAT, or extended-life coolant formulations.

Installation Notes

Installation is performed by qualified automotive or fleet service technicians. Before adding coolant, ensure the engine is fully cooled and the system pressure has been safely released. Follow vehicle manufacturer service procedures for flushing and filling the cooling system. Dispose of used coolant in accordance with local environmental regulations — do not pour down drains or onto the ground.
