Question type: Maintenance & Repair

Hey everyone. I really need someone who knows abouts
cars advise. I currently am driving a Nissan altima 2003 3.5
SE and it keeps over heating. The car overheats 3x faster
when the air conditioner is on. I've changed the thermostat.
And had the radiator checked out but still. Coolant
container or engine oil seem to be mixed . The air
conditioner works and the heat. The car goes into a neutral
state when it gets too hot.the slip Can anyone give me
some possiblities what could be going on? My check
engine light won't turn off  nor the slip light and two others
as well. I'm getting different answers from people. I have a
2 yr old that gets therapy 5 times a week and I really need
this fixed.  Please help ?

If you are getting coolant and oil mixed either in the engine or the coolant reservoir you likely have a head gasket issue or a cracked cylinder head. Is the car losing coolant?
