The radiator itself is a big deal at this point, with all these trucks 20+ years old. If vibration hasn't compromised it, a lot of the tubing in the core is likely getting plugged even with good PM practices. If the temp varies across the core in places, the cool points are clogged points - use a IR thermometer to read things, but you can physically feel the difference once it gets bad.
Another tip. Inspect and replace as much of the connecting hoseage as needed to restore it, too, while everything is getting handled anyway. A blown hose isn't as big a deal to fix, but will stop you just the same. All rubber has a limited life in the environment it lives in under the hood. Maker sure it's all good to go, too.

My Radiator started leaking right below the top tank. It would steam slightly... not sure how else to tell. I replaced it with a $230 aftermarket and have been on that for a year with no issue. Fairly easy to replace yourself as well as long as you follow the right steps.
Radiator/Water pump/Thermostat/ and all new hoses is the best PM I ever did. Makes me feel happy inside.
Use these instructions! Here @93Chewbacca Nailed it.
