That's too hot. Does your fan come on when you drive in traffic without AC? If the fan is running & it still gets that close to the red, its your radiator.
Jumper the fan switch (LH side of radiator) to make sure the fan runs. This also means the delay relay isn't preventing the fan from running. If this doesn't work, unplug the fan delay relay & jumper the socket between pins 30 & 87 then try again.
Then... drive slow or idle till the temperature climbs, the fan should come on by 3/4 or so. Use the AC switch to run its fan if you need to prevent the temperature from going too high. The temperature should quickly drop back to mid-green or just below.
Our '89 n/a never needs the fan above about 25 mph even at about 90F. If you need to go much faster, maybe your radiator isn't the best? OTOH, I don't know how hot it is where you live...
Post back what happens for each of these questions, & go from there.
