Question
need instructions to remove the heater core in a 1990 Nissan pickup to replace it

Answer
Hi Ron -

The heater core is replaced by removing the A/C ductwork on the passenger side of the vehicle under dash. You may also have to rempove the fan motor to gain access, however it is mainly the ductwork. Take note of how it is removed so re-assembly is easier.

Hope this helps -
aloha
