05 check coolant level on already--Car 6m/old!?
My check coolant level came on last night for a while then today no sign of it. I have not been around to check the level yet today, but I will. Just curious as to why this would happen on a 6m/0ld MB no temp problems or overheating on the car and its running fine. However, it's been extremely hot these past few days, but still how/why would this happen?------ A leak or just need to add more because of normal use? My dad says he has put coolant on his 1 yr old INFINITI FX 2 times already....not that he had any problems, but just because it gets used up and he is very meticulous with his cars. He says its normal....what do you guys think? Car has 6800k on it and I got it in mid january------my service A says it's not due for another 6,000 miles. Is this correct or should I take the car in? I'm going to first put some coolant in myself, but I don't want this to be a leak of some sorts.

In my situation, my windshield washer level was low, and that indicator came on first, and it seems like the computer somehow decided to indicate that the coolant level was also low...From then on, until I topped up the washer fluid, the check coolant light never came on again.

Adding coolant is not "normal"
Car cooling systems today are closed. The only way for coolant to go from full to a warning light is if it leaks...outside or inside the car (into the engine or transmission! Yikes!). Coolant is not consumed by the engine nor should it evaporate to the atmosphere. Did you ever check the coolant fluid level when the car was new to be certain that much leaked out? I'm surprised you even asked this question when you haven't even bothered to look to see if it really is low or a sensor malfunction.

They found something wrong with the fan (I think it was a bearing or something like that). They replaced the bad part, and it's been fine since then.

I'll watch the car this week and see if anything happens----- look for leaks and if i'm not comfortable I'll take it in then.

>This is not entirely true! The cooling system is closed
I thought that's what I said
>So if the engine gets too hot it can and will vent out
Again, that's what I said It is not normal for an engine "to get too hot". Either it's being abused or there is a problem.
>But of course this should not happen, but sometimes does when you are at temp and it is a hot day, then you shut the car off. Well when the engine is not running then nothing is moving the coolant around, no flow. So the engine block gets hotter, thus expanding the coolant and thus creating more pressure in the system.
That's why it's called an expansion tank. If the coolant goes from full to add in 6 months (like he was wrongly assuming) then there is a problem.
> Now of course by the OP's last post this was not the case!
So it was a sensor malfunction...thought I covered that. A simple look under the hood would have solved that problem.
> But it can and will happen sometimes under the right circumstances so it is kind of wrong to say it only happens when there is something major wrong.[/QUOTE]
You said "major" problem I said leak. It is not normal to leak fluid and the engine does not consume fluid....that's what I said. Enough said.

Re-read your statement I quoted originally! You never said it vents anywhere!
As for dropping enough to make the light come on! I have seen that in brand new cars dozens of times. Crap happens and the car heats up enough to make the cap release pressure. Or some idiot does not put the cap back on all the way! Also why I said an air pocket as they take a while to work themselves out sometime. Could be too much water in the coolant as well and causing it to boil! My W201 always has air coming out of the vent on the expansion tank, I need a new radiator that is why! No coolant loss just air pressure coming out due to the fact that when the engine is off it has no ablility to flow coolant so the engine temp will rise from its 95 degree running temp to 120 once the car is off for a few minutes! Why does it do this, well because they is no flow and the engine does not cool instantly once combustion stops. The heat dissapates very slowly instead, but not until after the rise in engine temp. Well since more hear means more pressure in the coolant world, then the expansion tank is the only place for it to go! If it gets above the set pressure on the cap, then out it goes. The only reason I commented at all is because you made it sound in your initial post I quoted as if there was a major engine problem. When I stated basically now in more detail is that it could be other more simple problems, such as air, bad cap, or loose cap! Not everything is a major problem that we all need to rush to the Stealer for! Maybe he was in the desert heat and the cooling system just could not take it and vented due to excess engine heat! Those tanks are not very big and do not have a whole lot of coolant to lose before the light comes on!

Look, go ahead and keep replacing all the cooling fluid you want. He had his question answered and you are entitled to your opinion whether it is based on reality or not.

Your advisor was a noob. they shoul dhave checked your windshield washer fluid, that's probably low, the 2 sensors are on the same circuit and are known to trip each other, same for the rear lights, one bulb might trip 2-3

if not they can change the sensor.
the sensor itself is 48$ cdn so I'd say about 35 $ us

my "check coolant level" came on. I put in more water into the windshield fluid reservoir. The "check coolant level" message was gone. Maybe the person who said that the windshield fluid reservoir and coolant fluid reservoir do go to the same circuitry.
