1998 TJ Wrangler Antifreeze type.

Hello and thanks for your assistance in advance.

I have looked all over for the type of antifreeze I should put in my 1998 Jeep Wrangler 4.0 with no success. The owners manual says how many quarts, but not the type.

Any suggestions appreciated.
Thanks.

Are you doing a full flush?
Zerex g05 is good stuff.

Get out and explore.

Yes, but was that designed for that vehicle. That is HOAT technology. Not sure its compatible with the vehicle.

I use the green stuff in all years of my Jeeps. Prestone All makes and models. I've never had any problems.

It makes no difference if you flush it and change it every so often. Your Jeep originally uses the old school green stuff.

I went through this, not with a Jeep, but with an older vehicle that used the older style antifreeze ( (Inorganic Additive Technology) the green stuff, which would be the same as originally came in your 98 Jeep. I flushed the system a few times, but was concerned that there might still be some of old antifreeze (albeit extremity diluted). I wanted to use the latest technology that would protect the innards of the cooling system. I used MaxLife Valvoline Universal Antifreeze/Coolant. and it has not given any grief.

It makes absolutely no difference if you mix the two. Just like people say you can't mix regular oil with synthetic, then they made "high mileage" synthetic blends. Guess what they blend it with? I still need my gluten free foods to eat with my wheat bread. Yuppies? or Democrats?? probably both. They whine just as much. Dems for 2020. Suicide is a better option.

What is your personal opinion on "high mileage" type oils?
