Antifreeze is not the same as coolant. Antifreeze usually does not have the same performance as coolant, as it is intended for cold climates (has antifreeze agents, so the radiator's contents do not turnt into ice). Look for a coolant intended for hot climates, as it has better anti-corrosion additives and possibly better cooling performace.
