how do you change a heater core on a 2002 Nissan altima 2.5
I have a 2006 Altima and it is doing the same thing.
The thermostat on the Nissan Altima should be directly behind the alternator. This will be on the passenger side of the car and directly under a large heater hose.
You have to be more specific what kind of actuator. The Nissan's have many different actuators: door lock, heater box, etc.

The heater core is under the passenger side of the dashboard inside of the housing that holds and covers most of the A/C an Heating system components. IT is NOT easy to change.

My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.
My 2005 Nissan Altima is doing the same thing. The car has no heat when the car is stopped. You have to be going at a steady pace for it to stay warm. I have had the car looked at, at a Nissan dealership but without paying $800 dollars it can't be fixed..and there is no guerantee that it will work after the work. The dealership guy said he has alot of people complain about the heater in the 2005 Altima. Nissian won't do anything about it he said.
