1998 Altima overheating?

[Sal329]

Ok guys I need some help. My sisters car is overheating. I have not looked at it yet as I am 5 hrs away. I will be goin there tomorrow. I figured I will replace the T stat and water pump seeing how the car has 130k on it and she over course has no idea when these items were replaced. Is there any where I can go to get some instructions on how to replace these items? What else should I look for? Are there any known problems with the coolant system on these cars? I know BMW's at 60k the radiator on V8's, resvoir and T stats on both 6 and 8 cyls are prone to need replacement. Thanks
