How much freon does a 2005 international truck hold?

There is no such thing as "freon" in an International truck. Freon is a brand name often associated with chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), refrigerant chemicals used in older air conditioning systems. However, due to their harmful environmental impacts, these chemicals have been phased out in favor of more environmentally friendly alternatives.

International trucks have air conditioning systems that use modern refrigerants, such as R-134a or its replacements. The specific amount of refrigerant required for your International truck's air conditioning system depends on the model and year of your truck.

Refer to your truck's owner's manual or contact an authorized International truck dealer or service center to obtain accurate information about the refrigerant type and quantity for your specific vehicle.
