Cooling question

My 96 analog guage will get to 260, the digital guage will only get to 220, which one is most reliable?

The analog gauge is non linear and by design not as accurate as your digital--trust your digital gauge

Thanks, makes you a little nervous watching that gauge creep up.

Unless it's "pegged" all the way to the needle stop, it is not reading 260.
Look real close, and I bet the needle is just shy of the shaded area on the gauge.

Here is a link to an online copy of the 96 owners manual in PDF format courtesy of forum vendor GM Parts House.

See page 2-96 for an explanation concerning temp gauge operation.

94 runs hot

My 94 coupe runs hot. DIC says 225 in traffic around 210 at speed. Had the car a couple of months. Outside temp low 90s. Is this normal for this model year?

225 in stop and go traffic is not at all unusual.
If your not moving, there isn't any airflow across the radiator fins unless the cooling fans are running.
And they don't come on until approx. 225-228 range (depends on year).

Running 210 at speed is not really normal, but depending on conditions it is possible.
At any speed above 40mph, there should be enough airflow across the radiator fins to keep the coolant temp in the 195-198 range.
