2.0 cooling system all connected?

[Ostranza]

I recently took 2018 Sahara in for oil change and asked them to top fluids at dealership and got it back and they were all in the same place. Dip stick in overflow is bone dry although I can see a little at bottom of tank, turbo tank is almost 2inches below MIN line and same thing with coolant tank for 48v battery. To boot the oil level is all the way to the top bend on the dipstick so way too much right??? I asked service about coolant level while I was there and when I opened the hood the overflow cap wasn't even screwed on. Guy goes and gets a jug that says Mobil Synthetic oil on it with "AGUA" written in permanent marker on the side. I wish I saw this before he was pouring it and it was coming out clear. Said how come it's not pink? Oh it is we mix it with concentrate to make a new batch every time it runs out he says. Then I asked him about the other tanks and he said they are all connected together. I said why the 3 caps then?

Anyway I bought the Mopar 50/50 mix and figured I'd do everything myself but wanted to be sure I'm not just supposed to do overflow tank like he did and leave the other two alone...they don't seem to be filling up.

Fill them all yourself with the proper coolant.
They’re not connected as far as I know, but I won’t say for sure. Some vehicles have them connected, some don’t.

Anyone know how to use this to pull the overfilled oil out the dipstick hole like it says on box? I got it to work with water in a bucket but can't seem to get any oil from dipstick hole or the engine fill cap????!

You never will, the dipstick tube doesn’t extend down into the oil sump. You’re just sucking air.

I'm surprised to hear that if the dipstick gets quite a bit oil on it and this kit specifically says it can pump oil out of a dipstick hole with the provided skinny black line but maybe this is the case for other vehicles and not this Jeep?

You would need to feed the line down inside the dipstick tube and into the bottom of the oil pan. If that’s what you’re doing, you aren’t going far enough, or you’re going too far and it’s curling back up. Either way, bad product.

Bad product is right. I got some 1/4inch poly thick walled tubing and tried again. Definitely got deeper and the tubing didn't collapse on (only the red tube did a little)me when pumping thick oil. It worked, now I'm going to see if coolant is leaking into the oil or vice versa and do this "Block Tester" kit tomorrow on the overflow tank.

I checked, they’re not connected. Fill to the min line, it’s hot outside. They all use the same coolant. MS-12106 or 90032

I went ahead and did this after doing the "block tester" test and it was all good. I did notice turbo one seemed darker and maybe foamy than the 48v battery one but no idea how the engine one looks due to its black tank. Any concern here?
