Nissan Xterra Heater Core
The Nissan Xterra Heater Core takes hot engine coolant from the engine and transfers it to the air inside the cabin. Located beneath the dashboard, the Heater Core has inlet and outlet hoses connecting it to the engine. Hot coolant is pumped through the hoses by the water pump. Coolant flows through the finned aluminum or brass passages of the Heater Core, and an air blowing fan blows air over the core to raise the temperature of the air inside the cabin. One can regulate the temperature by the valve controlling the flow of coolant or the door directing air around the Heater Core, allowing occupants to control heat output. In the air conditioned versions, the air first cools at the evaporator. Then, the cooled air is routed back through the Heater Core, so the occupants receive warm and dehumidified air flow. This part also helps in slight cooling of the engine. Every Nissan Xterra uses the Heater Core as an auxiliary radiator without modifying the primary cooling circuit. Regular maintenance of the coolant prevents clogging or corrosion in the Nissan Xterra system that would restrict flow. The Nissan Xterra's interior is designed for comfort while driving.
