Check coolant level see operators Manuel
hey all l need help. Coolant spilled al over the driveway. 2013 I got a check coolant level see operators Manuel warning. What does this mean, where is the coolant part, and what kind of coolant does it take?
Also I got the engine area high pressured wash and steamed with the electronics covered because of rat poop pee. Could the high pressure and steam under the hood cause this problem?
thanks

Before you start driving all over the hood, do us all a favor and fill the over flow with tap water and then have your girl friend start the car while you watch and maintain the level the over flow while looking for the coolant leak----don't drive around until the leak is found!!

I had the same issue about a month ago. Turned out to be a cracked Y pipe that connects to the turbo. Hopefully that's not the case for you but it is a common problem.

do you think it could be a rodent damage? There was rodent pee and poop and even found nesting under the hood

Yea I thought they would had issued a recall for such a issue. It does not even have sign of slow leak before bursting , mine was so bad that the whole hose dropped. I managed to pull in to the dealer , 1mile away from my home.
dealer noted this is a very common issue on the x166
i do suspect that the W166 have similar issue since the X166 and W166 are similar

Ah, i too got a message this morning "Check coolant level see operators manual", it was 17 degrees out this morning so not sure if it had to do with the temperature. I have looked through the MB manual, and it states that the coolant used should be 325 or 326, upon looking up the specifics of the 325, the part number shown was A 000-989-01-25. I have no idea if this is pre-mixed or not. I have a short day at work today, so will stop by the dealer to ask the details and report back. Hopefully, its not a broken "Y" pipe as we'll going to the ski slopes this weekend.

My y pipe was broken a few months back, but recently I have been getting this message when I start the car cold. Drive it a bit the message will go away. Or if I’m starting the car from garage (which is warm) also no message. I think in my case it was probably the mechanic was a little stingy when refilling the coolant last time and when temperature gets cold it gets slightly below the level?

byroncheung,
That makes sense, either way the GL is still under warranty so i'll have them take a look at it to be sure the y pipe isn't cracked. Hopefully, its just a top off.
I also started getting this message on occasion during cold start, starting with this brutal stretch of low single digit temps (degF) in the northeast US. My first impression was that it must just be weather related, as the tank seemed pretty full. I decided to come to the forum, and saw the subject has come up with a bunch of other people so I looked into it a little more closely. Turns out reading the coolant tank level is a bit counter-intuitive. When cold the level should be at the seam (there's also a plastic marker inside the tank), meaning you shouldn't really be able to see the top of the coolant level through the translucent part of the tank. My level actually is about 1.5" below that, so when I take it in for service this month I'll have them check for leaks since it's still under warranty.
Top it off in the mean time, but if it's only that low, it's probably not leaking.
The turbo line that leaks is ridiculous, it's a plastic part that bakes from the heat and fails, and the new one is just the exact same part. I've seen higher mileage trucks have it replaced twice already. There needs to be a part revision for this or they will keep failing.
Well that's disappointing about the failing part. Hopefully this issue is just nothing. I've been completely hands off since I picked this up a couple years ago, so I have no idea what the level was at leading up to this.
I had a fun bout of coolant issues with my old VW. The leak on that one was so slow it never made it to the garage floor and took about 6 weeks to reach the low level warning. I was having flash backs to that when I saw the low level.

My situation is exactly the same (coolant level maybe an inch lower than the plastic marker). I’m just not sure if this is due to yet another leak (If it is a leak it will be a really slow leak), or just because it wasn’t filled up enough when the leak was repaired last time. For now I just ordered some coolant, going to top it up and see what happen...
