Does 2.0 T has coolant level sensor?

Too much work. :giggle: Seriously, though, do they expect us to do this on a regular basis?
I would just to be on top of it given Jeep's reputation for losing coolant suddenly

The coolant will leave a pink residue where-ever it is leaking from, though it may not be much. I had to search a bit, but found traces under the reservoir tank and a little down below around steering shaft area. really not much. If the leak is small so it is coming out more as steam than an actual liquid leak, it doesn't seem to leave a large signature to identify with. I'd use an inspection mirror and flashlight to check under the reservoir and around the fittings there, check the left side of the engine towards the front where the water pump inlet is, and pull the top engine cover and check around the T fitting on top (right of center and back a bit), also check around the radiator seams. If you're losing that much it should have an obvious patch (although maybe small) of dried pink & whitish powder residue. Mine never left a drip on the garage floor, but leaked under pressure. Good luck!
Won’t always leave residue. What happens is the tank fails at the seams when hot/under pressure and coolant escapes via steam/vapor and once the tank cools down it “welds” itself back together making it hard to track the leak.

Yeah, I can agree with that. To be more clear (and in line with your statement) mine wasn’t visible until the tank was out and I could inspect the area without the obstructions. That was how I found the trace residue on the tank/tank mount and below. Without removing the tank, yeah, essentially not there. My bad, I’m way too analytical & literal sometimes. Microscopic evidence doesn’t always count 😄

You’re good lol. My tank was bad. Zero residue to be found lol. Was beyond aggravating to figure out

The opaque coolant reservoir, paired with long-documented coolant loss, functionally compels it. 👍

The reservoir is black because of the polymer chemistry that is required to endure the heat of the adjacent turbocharger assembly. That's why the separate intercooler circuit reservoir, behind the driver's side headlight, is clear. You've been monitoring the fluid level in that one, also, yes? (Edit: Applicable only if you've the 2.0T in your new Jeep. :) )

The OEM coolant reservoir on my '21 includes an integrated dipstick on the cap, and a separate fluid level indicator in the reservoir itself. All you need is two minutes, a cool engine and perhaps a flashlight. Done.

I check the engine fluids and tires pressures in both of our vehicles every Saturday morning. Once you get used to doing such a task, it becomes automatic and easy.

Did you replace the coolant tank and pipe as mentioned @SIGP2101 before you noticed the tank empty for the second time?
No, I did not. Still trying to establish the leak. No visible trace. Any way to pressure test only the tank? I will have to evacuate coolant, remove tank and find the way to test it somehow.

It Finally I wiggled part out to be able to inspect it. It looks like that there is factory inflicted pinch right at the flange as you can see it on second image. This car has never been to any mechanic and this is first trouble after 5 years of ownership.
