Cooling to well or is something broken?

[trainguy1989]

On my 94 ATX the temperature gauge only gets to the "N" or "O" (usually closer to the "N") on hot 90 degree days. I have even driven it 150 miles and it will not even get past the "O". I have read about the thermostat getting stuck open or the temp gauge sending unit going bad. I do not know what the most likely cause is. I have not driven the car enough to determine if fuel economy has suffered. Every time after popping the hood after running her for a while, she seems pretty damn hot, but the coolant has not reached the hot line on the reservoir (unless I need to add some coolant).

So, with all the experience you SHO owners have, which is a more likely cause?

Thanks,
David

Well, I replaced the thermostat and the gauge still does the same thing. I guess this would have to be the temp sending unit, right?

I was about 109 here on Saturday. I drove about 200 miles and never went above the "M". I also have a triple core rad

So you're gauge is within the "NORMAL" range, you have no diveability issues, are not getting poor a mileage and you made sure you're thermo was good. That gauge is very inaccurate, it works on resistance IIRC I really don't think you have anything to worry about.

If the car is running within the normal section on the gauge, that means it's normal.

Replace the sensor.
