Proper Coolant for 2003 Jeep Wrangler Sahara 4.0L Auto

My trusted friends, I have been scouring the internet and this forum, thread after thread, and I can't seem to get a solid final answer.

I own a 2003 Jeep Wrangler Sahara 4.0L Auto.
It has 80,000 miles on it.

The coolant inside is at the 'fill' line, even when the engine temp is hot, so I know it needs to be topped off.

The color of the coolant is an orange/rust color.

What is the correct coolant to top my cooling system off? What would the exact brand name be?

Note: I have no plans or intentions to do a coolant flush, mainly because I travel too much and don't have the time to actually do so. I'm simply looking to just top my coolant off and keep on truckin'.

Second Note: Everything is stock, nothing has been replaced.

You need HOAT coolant. Most people skip the dealership and just buy Zerex G-05 from an auto parts store, which is HOAT.

Zerex GO5 is a good HOAT choice.

If NAPA doesn't have it on hand, check if Grainger has it.. I get my Zerex there and it's a few bucks cheaper

Houston must have reached its bandwidth limits

Thanks so much guys!!!

Sorry to make this thread longer, but would you guys recommend a coolant flush? I'm thinking maybe I might do it.
80,000 miles on it, haven't changed the coolant ever.

Also, I was at Advanced Auto Parts, and they're carrying this Prestone 50/50 coolant that claims you can add to "ANY vehicle, ANY color coolant."
Have you guys heard of this coolant? Thoughts?

Hi all

This is for 98 model year.....

Honestly I have checked the FSM and in the fluid capacity and cooloing section all it says is 2.5 ltr,- 8.9 qts. no mention of type or color? I have always used the green color, never red. it is probably because of the year model I have. Plus I always change the coolant every two years, replace thermostat, cheap insurance................................

Green is fine for you. IIRC the switch to HOAT was 2001,
