Prime antifreeze+coolant (concentrate) is for all vehicles; all makes, models, years & fluid colors. The extended life formula is safe for use with all types of metals & rubbers; including aluminum. Prestone Prime will guard against temperature extremes and the effects of rust, corrosion and premature water pump failure.

Changing Your Antifreeze And Coolant

Top-off:

Low coolant means less heat transfer, which in turn risks the engine overheating. Too much coolant also risks damage to the system, as coolant needs room to expand when cold. Without this room, parts can become cracked and damaged. Make sure you regularly check your reservoir, and top off to the fill line as needed.

For Vehicles with Expansion Tank:
REMOVE pressure cap WITH THE ENGINE COLD.
FILL tank with Prestone^® 50/50 Prediluted Antifreeze/Coolant to “cold” fill line.
REPLACE cap securely* (ILLUS. 1b).

For Vehicles with Recovery Bottle and Pressure Cap on Radiator:
REMOVE radiator cap WITH THE ENGINE COLD.
ADD Prestone^® 50/50 Prediluted Antifreeze/Coolant to within one inch of the top of the radiator cap.
TOP OFF recovery bottle to “cold” fill line* (ILLUS. 2b).
