what temp is it running at? Best thing to do is get a 160 degree thermastat
if you have the time. If your fan is computer controlled, you might think
about reprogramming it to kick on at 160 degrees as well if you want your
engine to live a longer life. The hotter an engine runs, the more rough it
feel. The factory installs a 190 degree thermastats and some people say
that's almost too hot. Running at or above 210 will noticably make your
idle rough. If your engine runs near 210 the thermastat won't help because
it should be open anyways and the fan should be on. If it is an overheating
issue, try flushing your coolant system. Have your waterpump checked out
and replaced if need be. Have someone make sure your fan is pushing enough
air through for adequate cooling. Maybe install a new temp gauge to make
sure it's accurate.
