Changing a heater core on a 4 runner with AC requires discharging the AC, removing the dash and then removing the heater box. The job is around 6 - 8 hours for a shop to do.
AnswerActually I own a 3.0L not sure about the 2.4L but you dont need to discharge the A/C at all. Basically you need to take the whole dash apart yes, it is fairly easy just remember where the parts go back into place.

After flushing coolant and replacing thermostat heater now throws out cold air on a 2000 Toyota celica?
Flushing sometimes frees up mineral deposits that then clog up your heater core. My mechanic told me to never flush a Toyota as the heater core was low in the engine. That is, only drain and fill when doing a coolant change to prevent dislodging the deposits.
