2.0 Liter Coolant Flush/Fill

[jeffk487]

This is my first Turbo Jeep and I want to do a coolant flush and fill. I have read that I need to change the coolant in the Turbo System and the Engine itself. I cannot determine if these two systems are independendent or not. I am assuming they are one system, draining and refilling main system would replace the approximate 9.5 quarts for engine and 3.5 quarts for turbo system. YouTube channels usually answer these questions but none have mentioned it. Can someone let me know if they are the same or independent system? Also anyone have a good link to YouTube video on this? Thanks!

And all I'm saying is that until or unless I see PROOF of why the service guidelines should not be trusted, I personally think it's silly to not follow them. Again, in almost 30 years of doing this Jeep thing, I have yet to see an example of why they shouldn't be followed.

It went from 5w30 to 5w20 to now 0w20. I've personally owned Wranglers with 3.6L that have required all 3 and for each, I've just followed what was stated to use in the owners manual and without any problems.

As I've stated, this is just me going of of my personal experience and not my imagination or what I can read on the internet. But again, that's just me, what would I know.

No disagreement. Just proposed an answer to your question for a possible why.

There was a Chevy truck or GMC truck that suffered premature wear and a recall for the thinner oil. This is the case I see most often cited for using 5w30 vs 0w or 5w20. GM gambled on a shortcut to get a bit more mpg and lost.

Thankfully the Biden era EPA unreasonable mandates have been rolled back. Personally, I don't think mpg should be regulated, just the amount of non-CO2 pollution coming out the tailpipe. Let the market work on mpg vs cost.
