Heat question - turbo

[NHTerrys]

my new 19 JLU turbo seems to put out cabin heat almost immediately on startup - is that normal with the turbo ?

Yup normal for the 2.0L... Awesome in the winter.

The 2,0 T sure does run hot, oil temps 190s, coolant 212. Trans fluid temps high as well, 180s.
And that's with ambient air temps in the 50s, not working hard ,rpms under 2000.
Synthetic fluids will have to perform well, fingers crossed

190*F is certainly not “hot” by any means. Many modern engines run oil temps over 210* to evaporate any water/condensate in the oil, this extends the oil life and reduces corrosive engine damage. As an example, my 2015 Challenger ScatPack averaged between 210*-220* most of the time, independent of the ambient temperature.

The 2.0 coolant heats up fast because the exhaust manifold is water-cooled, this part of the cooling of the turbo which is attached directly to the head.

My 2015 JK would run up to 226 water temp pretty easy.

mine does too, unless I put the HVAC on auto, then it will gladly blow cold air in the winter. I'm told that's a normal feature.

Yes, the coolant is heated very quickly because the exhaust is water cooled. Few other engines are.

It’s not a bug, it’s a feature!

I would have paid good money for this feature back in my CJ days! LOL!

That 'splains how it goes from stone cold to operating temp before I get out of my driveway in the winter.

This means top quality Synthetic lubricants to take the heat

Uh, yeah. That’s why Jeep recommends a top quality synthetic in the manual. You read that, right?

Don't worry; likely just an angry V6 owner who made the wrong choice

Frankly, I love my Hurricane!

On my 2020 2.0L, I was doing 220 - 226℉ oil temperature in Vegas summer at 105℉. With temps in cool 80s now in September, I barely reach 210℉ climbing a hill, but hover around 199 - 203℉ downhill or on flat road on my 23 mile commute to work.
