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'. :cheers:

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.

You are too kind. I was going to make a snide remark about Google not working in Houston this morning, but figured I'd withhold.

Most can order it in.

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

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,
