Passat (B5) :: Check Coolant Level Warning Will Come On Occasionally
Dec 29, 2010
When I start up the car in the morning, the infamous "STOP!! CHECK COOLANT LEVEL" warning will come on, and then shortly thereafter it will go away. I topped off the coolant level (with the pink stuff of course) and yet this light will come on occasionally. It mostly comes on first thing in the morning when the car is started up and cold, and *sometimes* come on when the car is warm. Fluid level is all topped off. What gives?
I was reading that there is a fluid level sensor that sometimes goes bad? could this be it? I changed the coolant temp sensor back in the summer of this year. (not sure if that has anything to do with it?) Not sure if I have a leak, cause I look under the car in the morning and I have no spots of coolant anywhere.

At the end of last winter, I got the warning flash that my coolant level was low. So I topped up (about a pint or more)About 3 weeks later I had to go through the same scenario !! but then it started to get hot outside and my air conditioner mode took over and lo and behold - no more coolant loss.!!?? Now that winter and cold weather is back - so is my leak!!
So I run off to the local dealer and they get the car up. And drop the belly pan with the engine running and the heat cranked up. the mechanic said he found a dripping hose coming from UNDER the intake manifold.
The engine is a 2002 2.8 v6....

I have added a quart of recommended oil per the manual (the dipstick is now reading optimal oil). The warning is still on. What actions can be taken and what was the outcome? I am assuming that if the warning is not gone in the morning the sensor is bad.

When I got the STOP check coolant level message on my 2002 Passat glx. I pulled over as soon as I could and then I began to over heat. The coolant level was good, actually it was a little high. The check engine light also was blinking. I replaced my water pump about 70K miles ago.

The "stop!" check level! alarm sounded as I was parked last evening...
Looked under car and a gigantic pool of coolant flooded under my car.
Where to look under the hood for loose or broken clamps or hoses that may be the culprit. Which hoses (color?) are the ones to check?

I was cleaning my passat the other day and I took my air filter out, however I didn't disconnect the wires and hoses on top of the box, I just raised the top cover up and pulled the filter out and cleaned it and checked it and put it back in, I also took out the cabin filter out and cleaned it and put it back in too, then I started the car and took it for a ride and the car started over heating, it keeps giving me STOP CHECK COOLANT warning and the temperature rises all the way to max RED.
I check the coolant level is at level and the radiator fans are spinning, however I noticed the lower hose that goes from reservoir to the radiator is cooler than the other hoses, what could be the problem? The water in the reservoir is hot too, could this be from a faulty thermostat? a sensor? or somewhere I read there is a fuse somewhere in the engine bay? I'm not too familiar with these 1.8t engines, the temp sensor was acting funny before too like sometimes it would go all the way to zero and stay there and go up and go down to zero and then raise, which I think there might be a bad connection or bad sensor.
I forgot to add the car is a 2003 1.8T.

My friend bartered for a '99 F250, 2wd/auto, 4 door, 7.3, 258k miles.
It had reportedly sat for one year, though the expired registration sticker and other things point to it sitting for two.
It ran low on oil, sputtered and died. Oil in the degas tank. Filled to oil to mid way on the hatch marks on the dip stick.
I drove it 25 miles to my house, and the oil level is not reading on the dip stick.
The sludgy fluid level in the degas tank is unchanged. Where is the fluid going?
I will refill the oil to see just how much it lost in the 25 miles if it important to someone, but I prefer to not waste the oil.
My first plan is to remove, inspect and replace the oil cooler o-rings. Even though the dealership charged him for this, I don't trust that they did it right. I think it is the easiest and mostly likely place for oil getting into the coolant.
It does have a really long crank before there is enough low pressure oil for it to start. At the moment I think this is a separate issue.
The dealership also charged him for a replacement injector. No idea if they replaced the cup or not.

About a month ago I noticed the coolant level looked a little low. I attributed it to the fact that the engine was warm after driving. Tonight the coolant light illuminated and the mfd states the level is low. Sure enough it's quite low.Is this normal for the R? I know my MK5 GTI burned oil like crazy. Should I be concerned?

While driving my 04 w12 a few months ago i noticed a "stutter" or brief jerk while driving. the next morning i had a "coolant level" warning. i took the car to a mechanic i use who diagnosed the problem as a broken coolant line involving the transmission cooler, with the result that coolant migrated to the atf. indication was that the tranny was toast, along with the atf cooler. I authorized a repair (not inexpensive), keeping costs down by installing a used tranny. since the car was "fixed" i still got a "jerk" usually in fourth gear, sometimes in third. i took the car back and was told that the tranny was flushed numerous times and the transmission was reflashed. i picked the car up yesterday, but i still get the "jerks", now usually in third gear.

For the last several days, most of the times I've started my car I've had the Red "Check Coolant Level" message on the MFD - accompanied by a tone / chime.
The first time it happened, I was a tad below Min, so I added a 'glug' of G13 to push it back up into the normal range. Everytime I've checked it since, the level is in the normal range.
So how is the level "sensed"? I had a new coolant reservoir put in about 18 months ago, so my "hope" is that it's not actually that (though those are really cheap).
Is there something else I should be cleaning / renewing? Maybe as simple as the electrical connection on the reservoir?

Turned my car on this morning and heard a long loud beep, i look at the car at its saying "Check coolant level low - Check owner's manual"
Turn the car off (engine still cold) pop the hood and coolant reservoir is almost bone dry, way below min level. Check underneath, no apparent leaks, no puddle, etc. Turn car back on, no warning light, drive to dealer, the service advisor looks at it and says there should be no way it's that low that soon.
He said in the morning its common for it to be low but after the engines warmed up it should be higher (and it was) but still below min level. He thought that it was strange and topped it off. Said to keep and eye on it and it will gradually gone down since its 40% water and when it slowly evaporates the level should go down.
So not sure if i have a leak or my car came with low coolant from the factory or something else even, but check your coolant levels

I've got some problems going on with my 2001 VR6 Jetta. I was driving home from my way to work this evening and all of a sudden the indicator light came on and told me to stop and check the coolant level. Within about three minutes the car was already up to about 200. I pulled over to a gas station and the coolant reservoir was completely empty. So I began to pour coolant in the reservoir and fill it up I notice I was pouring a lot of coolant so I went to the hood looked on the driver side below the bumper and water/cool was pouring out everywhere. I inspected as many radiator hoses as I could and did not find any cracks. The water seem to be pouring out from around the thermostat housing. My question would be since I don't know whole lot about cars would they crack thermostat housing because you need to have this problem?

So I recently bought a Chevy Impala with about 150,000 miles on it. The check engine light is on and sometimes it will tell me my coolant levels are low. I filled it up with coolant and the message still comes on sometimes. Also, when I'm driving, I can feel my rpms go way up when I press the gas, but they car won't accelerate for shit. Sometimes the check engine light will blink, which I've heard is for safety, and my car will barely accelerate at all. I can drive it around town easily the way it is now, but I don't want to risk ruining it. On top of that, my radio and lights will cut in and out sometimes and get better the more gas I give it.

On starting today I had an alarm to check coolant. Never had this before - and the expansion tank was dry. No visible signs of loss - Oil seems fine and free from contaminant.. so I guess not the head gasket!

My 2015 F350 6.7 has 13,400 miles and displayed the check coolant additive warning as I pulled into town from an 850-mile round trip this weekend. If the radiator in 2015 is still the same as the one used in 2012 etc discussed in another thread?
I will call my local dealer tomorrow. I do not see any obvious leak at this point. I had the oil changed before taking the trip and assume all fluid levels were checked.

On Sunday I'm driving to the store my LOW COOLANT light goes on. So I buy some coolant. I get home let the car cool off and check my radiator, it is full. My coolant recovery tank is also at the proper level.
Been three days already checked levels again and I'm not losing any coolant.
What the car is NOT doing:
1. Not losing fluid
2. Not running hot
I'm thinking coolant level sensor?

I have a 2004 W8 Passat wagon. I just went over 60,000 miles and was wondering how to reset the service warning for coolant servicing.
