Sonata I45 (LF 2015+) :: Coolant Reservoir Tank Completely Empty?
Oct 21, 2016
I just purchased a 2015 sonata last Friday from a large non Hyundai dealer. An hour ago while upgrading my headlights i noticed the coolant reserve tank was completely empty. I am going to check the main radiator level tomorrow because the engine was still hot at the time. I am hoping it is not a blown head gasket, i did remove the oil cap and noticed a very small amount of greyish oil in the cap threads other than that it looked good directly under the cap and inside the hole. Should i call my local Hyundai dealer or just fill the tank back up? I am wondering if it just burned off over time and the original owner never filled it back up. Also what type of coolant is compatible?

It has happened to me several times.. The car asks me for coolant but today the reservoir was almost completely empty... I have no leaks and my cooling systems is working fine so where does the coolant go?

Was under the hood today and noticed the coolant tank is completely empty. Car hasn't overheated or anything...just odd that it apparently wasn't filled correctly from the factory. It should be in the middle of the high and low markings, correct?

I was driving my 2008 Santa Fe last week (before I went on vacation) and noticed the the A/C wasn't coming through quite a cool as usual (almost felt like the vent was on w/ no AC). Then after about 10 minutes of driving I noticed the thermostat on the car get to about the 3/4 line pretty close to the red lines.
Luckily I was home so turned the car off and popped open the hood. I noticed the reservoir tank was empty and there was some coolant that dripped down on the fans & a small pool of coolant on the engine block right under where the oil is poured. (nothing has been dripping under the car)
I added a little coolant to the reservoir tank and the next time I turned it on and let it run for ~10 minutes, it was the same thing.
Anyway, I came back from vacation and opened the hood to try and identify exactly where the leak was, and ran the car for ~30 minutes, with A/C on full blast and the car didn't overheat or leak anywhere. Coolant tank was still full from when I filled it the first time.
What could have caused the leak/overheating in the first place?

Why my 96 dodge neon is leaking coolant. I was checking my oil and I noticed the reservoir tank was half empty, so I assumed it was nothing out of the ordinary since it's a 17 year old car. When I filled it though, it came pouring out of the tube that sits right under the tank. I'm capping it off every day before I drive and it holds, but it's definitely got a slow leak. It seems to only hold it for 4 days of driving for an hour. My temperature gauge stays at the normal level, but you can smell the antifreeze burning and the engine's running hot. I'm not too mechanically inclined, but what could be wrong with it? I've recently installed a new alternator and clutch cable and found out my valve cover gasket is leaking. I really want to save this car instead of getting a new one.

2010 MKVI GTI ... Woke up this morning and there was a puddle under my car. Reservoir was completely empty. I jacked it up and got a look under while running some coolant through and think I found the leak.
What this is, and if it's leaking as it appears to be and if a choad can fix it, or if a certified mechanic must be engaged.
It seems to be dripping all along this clam shell along these star nuts.

My 2015 2.4L Hyundai Sonata randomly started overheating today. The coolant tank is full and it never did this before. The temperature gauge goes up and the information display says car has overheated.

I have a 2006 3.5L Sante Fe. and i noticed there were coolant drips under the car and that my coolant reservoir was empty. In the engine bay below what i assume is the water pump i noticed the coolant pooling (See Photos). I am not sure if the seal is bad where the top radiator house connects to the water pump (circled in red, or if the thin metal line (circled in Blue) sitting in the coolant pool would have anything to do with it, since it seems to trace back to the radiator.

Back in February, received a light and discovered that the inverter coolant reservoir was empty. I refilled the reservoir and cleared the code. Today, only 3 months later, the same thing happened. I don't see any wet hoses, puddles, or obvious signs of leakage. Where all my coolant is going? What steps should I use to properly troubleshoot...

Today, I was greeted by a big red STOP! warning from my 2000 Passat 6 cylinder. The car drove fine last night. The coolant reservoir appears empty and has brown residue all over the inside. I notice for the first time that there is pink fluid on the floor -- I'm assuming this is the G12 coolant.
It's not a hot day, so I put in distilled water, turn up the heat and drive my Passat (trying to stay under 2k rpm) down to the dealer. They say that the coolant from the oil cooler leaked into the oil (and presumably, vice-versa).

2008 Santa Fe 2.7 105k miles Timing belt replaced two years ago at 80k miles I have no smoke, no sweet smell, no milk on oil dipstick, oil looks as clean as honey, no crustiness anywhere, no wet spots under hood or car. Yet my coolant reservoir was empty when I did my last oil change two mos. ago. I filled it up then. Today I checked it was just below the min. line. Car runs like a top, but I'm going to have a pressure test done today. I thought head gasket issues were very rare in these cars.

1999 Honda CRV. Just took a 3-hour highway trip. Before trip I topped up coolant reservoir which was a little low, but radiator was full. I did notice some dried white spots on the front of valve cover and spark wires. Wasn't sure what it was, but now realize it was coolant residue. Probably only 1-2 cups were missing from the reservoir, so the leak had just started.
After 3 hour trip, checked engine compartment again. This time the reservoir was totally empty (radiator still full) and the engine was well sprayed with greenish coolant residue. The radiator was cool by the time I checked it, so the leak source wasn't obvious, but it looks to be coming from the seam where the plastic top meets the aluminum.
I will replace the radiator when I get home, but first have to drive the 3-hour return trip. Will it be OK as long as I start full of coolant and keep an eye on the temp gauge?

I noticed recently that I have a coolant leak in a used car that I got a few months ago. I've been driving this thing pretty regularly at this point, but I haven't noticed any overheating. The engine temp stays shy of the midpoint line on the meter, both at speed and in idle.
The coolant reservoir was empty a little over a month ago, so I filled it up. A few days ago, I took a look at it, and it was empty again. I refit a hose that was a little loose and decided I'd just wait and see what happened after driving it some. Over the past few days, I've noticed slight decreases in the coolant level each day.
Today was no different, except that after I drove for about 15 minutes on probably the hottest day of the year so far (about 95 degrees, don't know if that matters at all), I noticed there was coolant sprayed on the hood. I opened the hood and there was quite a bit of coolant pooled on the far left of the radiator top, right between the coolant reservoir and the radiator pressure cap. What's going on here?

1,500 miles ago my car had it's 30k service. Today, i got "CHECK...". At home this evening i checked the inverter coolant reservoir, it was empty. I've added 1L of de-ionised water (which got it to full, and i see turbulence in the fluid) until i can get the correct fluid.

Had overheating issue with the wife (she doesn't monitor fluid levels like she should). Now you can't operate it for more than a day or two before the reservoir is super low to empty. Mechanic coolant is going into the engine, probably through the intake manifold. Says investigating further will cost a ton. What can I do cheaply to figure out what's going on before I give up? I followed her when the engine was started from cold & could see water vapor (more than I would expect) in the exhaust until when I figure the engine reached full operating temp. It has about 225k and is the 6 cyl engine, btw.

I've got an '08 Cobalt. There is a large leak in my coolant system. The plastic reservoir is empty and if I add coolant and start the engine it all gushes out of a hole in a piece of plastic on the side of the radiator. Can I drive it to the shop if I watch the engine temperature or should I have it towed? Is the engine temperature measurement affected by the lack of coolant?

I just noticed this morning that the coolant tank (close to radiator) is empty. The other coolant tank level is normal. Big surprise! I thought they are connected, and coolant can flow between them.

While servicing the bosses 121k 6.0, I noticed the coolant resevoir empty. It took 1 1/2 gallons to bring to proper level. Returning under truck to install drain plug, I noticed coolant coming from rear of the engine(right side). And of course Ford has changed the cooling system cap, so I wasn't able to pressure test it to pinpoint the leak. Started the engine and seen coolant coming from the left rear as well. I've been reading here to see what others have been seeing, (EGR cooler, head gaskets). With all the heat shields,not much room to look.
After work I did go and buy the adapter to test the cooling system. With any luck I will be able to see leak better.

I have a 2000 Dodge Neon with a 2001 Neon motor in it. I have just recently had problems with the car overheating. So we started diagnosing it and replaced parts that we thought were wrong. We replaced the water pump, thermostat, radiator cap, and timing belt. The problem that I am having is that the car won't take coolant out of the reservoir tank. I have bled the air out of the cooling system and it still didn't fix the problem.

2007, 4.0L, Explorer, 113,000 mi. Week ago noticed coolant expansion tank empty while hot and cold. Looked inside ex. tank and looked like it had not seen any action in a while. Looked inside radiator and coolant level was about 1 inch to 1.5 inches below bottom of rad. cap would be...approx. level with rad. seam, where black plastic top of rad. attaches to metal portion of rad. I filled expan. tank to "cold fill" line. Kept an eye on it while doing light, around town driving. The expan. tank level (cold-fill) didn't change.
Friday, my wife returned from work (30 mi., interstate drive). After being parked for 45 mins, went out to find fluid puddle at very front of car. Expansion tank was empty. Looked in radiator, and it was about one inch to inch and a half below bottom of rad cap...about level with rad seam, where the black plastic top is attached to metal. I topped off the rad. this time, along with filling expan. tank to cold-fill line. Turn car on, and after warming up coolant starting coming out from what appeared to be the seam at the top of the rad., where the black plastic portion meets the metal part of the rad.

2000 Chrysler 300M with 142K miles. Was a very reliable car until recently.
Problem began with boiling coolant in the reservoir tank. Then began to lose coolant at a high rate. I tried stop leak products and replaced the coolant frequently for a couple months. Some of it kind of worked, but the problem always returned. The car drives fine for about 10 highway miles then begins to steam out from under the hood on the passenger side. It gets about half way up the temp gauge, but does not really overheat. I usually stop when it steams out, let it cool, replace the antifreeze, then do it all over again. I've also tried a bunch of other things too, e.g., radiator flush. None of it worked.
The mechanic wants to replace the radiator. Says the system does not have pressure so there's no real way to determine if there are leaks in the engine. But he does know that the radiator is no good. I'm okay to replace radiator, but don't want to do it just to find out ten minutes later that I have a blown head gasket, which I would opt not to fix. I have read the tell tale signs of a blown head gasket, such as coolant in the oil, but there is none. My exhaust is white, but it's 5 degrees outside and it doesn't look whiter. I have seen some coolant on the ground at times.
