#77700-VC5083A Heater Kit - RTV-X900 X1140 X1120D

(2 hours)
This is for replacing the heater core. For better access, remove the hood by undoing two top bolts and unhooking the hood strut and wiring. The heater core has one screw and nut holding it in place under the hood, 3 wires, 3 vents, and two coolant hoses (one has shut off valve). Inside the cab there is one bolt in the firewall, by the accelerator pedal. Once the heater core is loose, just wiggle it out from under the dashboard.
