2017 GLE350
coolant change interval etc

I have a 2017 GLE350 4matic. at 70K miles now. Is coolant change recommended? Ever? I can't seem to find reliable info on this one. If so, what coolant?

I'm about to replace both batteries....they are original, and performing well now, but It's about time.

Thanks!
Tom

All lubricants / fluids have service intervals / life spans. ICEs are a harsh environment, heat & time take their toll. I always hate when I see trans fluid is not readily serviceable anymore. Built in obsolescence...

2017 should have chem pack build into coolant tank, who gives it 15 years life/100,000 miles
Whenever coolant is replaced the pack/tank should be replaced as well.
Check the manual to confirm.

Coolant is 150k miles, the maintenance booklet is is posted on this site. I think it is in the DIY in my signature, I can’t access it on a mobile device. I will check tonight and post if it’s not already there.
