2000 Jeep Cherokee rusty coolant

HI there,

you should drop off the lower radiator hose and remove the thermostat, all so remove the heater hose and flush all the coolant out until it runs clear, (make e sure the heater is on) replace the thermostat and the radiator pressure cap if its a few years old, replace coolant and bleed system, run up to temp check the heater is hot and that there are no leaks in the system.
