There aren’t usually any problems for 2001 cars with 2.0 motor with microclimate. Usually you don’t find problems with heating in Sportage with FE(16V) motors under the hood. Warming of Kia Sportage interior is possible with heat exchanger. All modifications of 2001 Kia Sportage with FE(16V) motor used exactly such type of heating exchanger. But if it needs replacement use 160 mm in height, 163 mm in width and 44 mm in depth equipment.
It also may be seen in Kia as bad heating, especially in 2001 year of production. While repairing Kia Sportage 2.0 purchase radiator with 160 mm X 163 mm X 44 mm (height, width, depth). Cooling liquid may flow out if exchanger in 2.0 Sportage is broken.
