A 3800 SC just looks right in a Fiero.

Good luck.

Checked the sending unit with my laser, car running, and hit from 230 to 250.  Just under the thermostat housing was 190-200.

Bought a laser thermometer. Fan was kicking on around 190 even though my temp gauge said 220+.
Replaced the temp gauge sending unit.

Everything looks good now.

Next step, AC.

Decided to swap fan switches with a spare 2.8 in my garage. Didn't help.  If anything, the car ran hotter.

Noticed the fan switch already in my Fiero looks a lot like the one on Rodney's page.  The fan switch from my spare had a much thinner base.

Can fan switches go bad? 

The radiator fan runs when the car gets hot.  I have the AC off.  Is there any other reason the radiator fan would run?  Basically, I'm wondering if the wires to the fan switch might be bad.

Try a laser thermometer to be sure of the temps you are reading.  Even a cooking one can be put between the radiator fins to check.   You can check at any point along the system looking for hot and cool spots.  Fiero's have been known to get air bubbles in the system when the radiator has been opened, possibly one occurred or moved to an undesirable spot.

HAven't convinced my wife to loan me her cooking thermometer.  Think she's afraid it might have the same fate my measuring tapes have when I lend her one.

Jacked the car up and followed your procedure. Heard lots of gurgling, but coolant was still at the top of the T-stat housing when I checked.  Went for a drive and it felt great!  Still warmed up to 220, maybe a bit higher.  I'm going to order the "210 on / 200 off" fan switch Charlie mentioned earlier.

The radiator hoses were not cold.  The upper hose was hot, and the lower one was warm.

Side Note: 
 1) Filled the coolant up when the car first started running hot.  It was an inch or two below the Add line.  Filled it above the Add line. 
 2) Noticed dark, non-metallic dirt(?) in the reservoir when I filled it.  Not much.  Just noticed it was there.

Went for a longer drive.  Same thing.  Needle went a bit above 220 and stayed there.
Started cooling down while it was still running in the garage.

Suggestions?  Ideas?  Is 225 too hot as a cruising speed?

Went for a drive this morning.  Warmed up nicely.  Went a bit above 220, then when back down to 220.  Exact midpoint on the thermostat.  Drove some more.  Needle didn't budge. Came home and fan was running.  Needle stayed straight down at 220.  Perfection.  Grrrrrr.....

Still don't trust the car.

I'll check the fan the next time I drive it.

The temp needle is at the bottom of the thermometer symbol with the key OFF and at the 100 mark when the key is turned on.

Didn't see/feel any crushed areas.  Both pipes were hot to the touch.
