And this is for a 05 Altima V6 correct. The MB symbol confussed me. Sounds like taking the radiator off is the big problem. Is that correct? Thanks for all the help. Sounds like it's going to be a job

That is correct. The MB symbol is for my repair shop here in California, we specialize in MB vehicles, but work on all makes. But yes this is for an 05 Altima 3.5L V6. It will be a bit of a job but don't let the radiator removal discourage you. It actually is not terribly difficult and is really only held on by a couple of upper retainers that are easily removed from the upper radiator support. After you disconnect the hoses and transmission lines the radiator and fan will pretty much just slide out. But all in all this will be a good days work if your not familiar with the vehicle.

I got the alternator changed. Now when I stop at a red light the heater goes cold. I figured out today that when I turn the AC and the recirculate off it doesn't do it. Any ideas? Thanks again

Was this a previous issue or did this just start after the repair? If it happened immediately after the repair it is more than likely related to the repair. Check your coolant level, a lot of times your system will burp after you fill it and drive awhile leaving room for much more coolant. Also check to make sure you have no leaks and that all coolant hoses are clear of kinks. Let me know what you find.
