Chris;
Try driving it around under "normal" conditions and then tell us
if it is still too hot.
Good Luck and Drive Safely

Hello all,
Just replaced my catalyctic converter, O2 sensor, temp2 sensor, and
temperature sending unit. I ran it until the fan kicked on and these are
my observations: First, the temperature gage gave the appearance that
the van was warming up quicker than usual. Second. while feeling the
radiator to determine thermostat opening the dash temp. gage read higher
than it used to. Lastly, by the time the fan kicked on, the needle was
just under the line indicating the upper end of the operating temperature
range. I have both the lower temp fan switch and thermostat in. The O2
sensor I replaced had been unplugged for the better part of a year. Is
it normal for a new sending unit to read higher thsn the old one? Is
there any way to 'calibrate' the new one? Is it possible one of the new
sensors is causing a lean condition resulting in higher temperatures?
During normal operation the needle used to hover right around the LED, a
little higher in stop & go driving, a little lower on the highway. My
test drive today (85 degrees) the needle hovered about halfway between
the LED and the hot end of the temperature range. Any thoughts from the
list?
