I have a 2003 Fronty with the 3.3L non-supercharged engine and i've been having overheating issues.  While warm and running the top radiator hose is hot and the bottom hose is cool to the touch.  If it is the thermostat, where is it's location and do you recommend NISSAN oem stuff or will a reputable name aftermarket one be good?

thanks,

Brian

My truck has 76,000 miles.  I'm sure the truck could use a timing belt.  The serpentine belt looks good-no cracking, no excessive slack.  I filled the coolant overflow on Sunday and when I looked today it was under "MIN".  I am planning on cleaning out the radiator with compressed air on the backside out.

I just thougt it was weird that the top radiator hose was hot when the bottom one was cool. 

Do you have to take off the brackets holding the A/C pulleys and etc. to get to the thermostat?

It looks like a time-consuming ordeal!
