The 420VU25 heater core is a crucial component of the International ProStar HVAC (Heating, Ventilation, and Air Conditioning) system for select models from 2010 to 2016. This heater core is designed to provide efficient and reliable heating solutions for the ProStar's climate control system.

It is designed to work with the vehicle's electrical and cooling systems, requiring a 420-volt electrical connection. The heater core's connection points include two inlet and two outlet ports for the coolant, as well as electrical connections for the heater elements.

When functioning optimally, the 420VU25 heater core effectively warms the cabin air, ensuring a comfortable driving experience during colder weather conditions.
