Sonata NF (2006-10) :: Heating Up / Coolant All Gone
May 6, 2015
My girlfriend's sonata was heating up. I stopped to check the coolant and saw it was all gone. I refilled it just 3-4 weeks ago.
I've checked the most probable stuff;
-There is no white smoke coming from the exhaust
-The oil looks and smells fine
-The colour of the coolant hasn't changed
-I couldn't find any leaks (looked with a flashlight for a few minutes with the engine running, there were no obvious leaks)
I really can't find what's wrong with it.

Just wondering if this is normal or not. I have a 2007 Sonata GLS. Recently I replaced the front and rear pads with ceramic pads and new rotors in the rear. My question is, is it normal for the brakes to heat up to the point that the lugs nuts are hot to the touch. As far as I know I am not doing any hard braking just normal driving in the city. But when I touch the rims and especially the lugs, they are hot and can burn to the touch. Is this because of the ceramic pads?

My 2007 has 160k miles and at just over 100k I had toyota change all the fluids. That was about 3 or 4 months ago, it's a taxi. I started noticing the heat was only hot above 83, and sometimes not even hot at high. I thought I was out of fluid so I added to the overflow not wanting to open the cap on a hot motor. It didnt take much, but made the heat come back on above 80 degrees so I did nothing else.
Last night I had no heat again after driving about 200 miles. The heat came back after turning it off for a few minutes, but I stopped at a gas station anyway when I got off the freeway.
The overflow was full. It was also cold. So were the radiator hoses, but not what looked like power steering hoses next to it.
I check that belt pulley was spinning when the engine was running, it was. It a new belt put on by dealer.
The car doesn't show any signs of overheating, and is driven 300 or more miles a day in town and freeway. The motor was of course hot, but not overly so. None of the connected components were hot like I would expect if was overheating.

Check out the pics, noticed car was overheating, let it cool down, got it home and found this broken hose (it was a crack in the hose before I broke it all the way taking the throttle body off). What is the part number for this hose and what else I should be looking for now that the car overheated?

I got my car back finally and on the way down the belt way i started sliding around a big turn and I get home to see my temp gauge way up and all the coolant went all over my engine .
I took it to a shop the did pressure test and that was fine, But the also found jell around the thermostat. The other thing they said is that it had air bubbles in it too. They said exhaust bubbles. But when they ran it it didn't heat up any more. They said its the early stages of blown head gasket ..
I took it to the dealer right away and they are telling me they cant find any thing wrong. Both places asked if i put stop leak in there but I never added anything to my car. So I am lost and don't know what to do.

My son has a 2007 sonata v6, daughter has one too. Both have about 130K miles, and both developed slow coolant drip leaks. I took off both hoses on both cars, cleaned the crud from the housings and replaced with new hoses and clamps. Problems solved in daughter's car, not so in sons car. I note that it looks like the area below the thermostat housing is wet - and thought that was from the crud/hose situation. But he is still losing coolant, even more now that its getting colder at night, and I's sure its not the hose connection anymore.
The car will generally NOT leak when hot, only as/when it cools off. I.e. puddle in the morning situation.
Looking at the diagrams, it looks like that "housing" is really a connection to the crossover pipe, heater hoses, other stuff (throttle body heat) and also contains what looks like a temp sensor.
I suppose any of these are possible, but my first thought was either a leaky temp sensor (or possibly loose) or something more serious like a cracked housing, leaking o-ring, gasket etc.

This morning I turned on the heat in my 2014 Sonata 2.0T and there was a clicking sound coming from behind the dash. Heat is now only blowing out for the window defrost mode and when I will not blow out of the other vents.

For a few months, I smell coolant when I get into the car. I thought it was the food left behind. Finally this morning I saw a small puddle of coolant on driveway. green color as we had a snow/ice storm. Lost about 3/4 inch coolant in expansion tank. still about low on cold freezing day.
I searched through this forum, not a common thing for the heater core.. There were cases about freezer plug not tight..hose clamp not tight. etc
My question is that where is the freezer plug? Any easier way to get to the the heater core.? without taking the whole dash out?

I have a Hyundai Sonata 2006. About a month and a half ago, I got in an accident and had to have the very front of the car repaired (they replaced the radiator, a/c unit, hood and a few other smaller things). The receipt that lists everything out in detail shows that the antifreeze/coolant was filled.
Fast forward to yesterday, and I'm getting an oil change. I also asked them to check out the front tire on the driver's side, as it seemed to have a slow leak. The woman at the counter wrote down to check the front left tire. A couple hours later, the guy calls me up and tells me that they found a nail in the right tire and will patch it up but nothing in the left. He also says that I am low on coolant and that he highly recommends I get the radiator flushed. Of course I told him not to do it since the radiator was just installed last month (well within the 90 day warranty).
I got the car home, checked the coolant level, and sure enough, it was way below the L. I haven't noticed any fluid under the car in parking spots or the driveway. I figured I would call up the place that did the repair work on Tuesday (it being a holiday weekend and they were already closed) and ask them about it. The receipt does say that it is an aftermarket part, but it wouldn't need to be flushed already, right?
Around 1 AM this morning, I heard a loud bang. It was my driver's side tire. What are the odds that the mechanic thinks that driver's side is right and the receptionist thinks that it is left? Do you think that it is more likely the patch failed or that the unpatched tire burst? Who should I call first on Tuesday: the mechanics that did the repairs about the radiator, or the mechanics that did the oil change/patch job?

I just bought a 2006 Lexus GS300 AWD. Bought it with 99k from a older gentleman who seemed like he took really care of the car. Gave me all type of Lexus dealership service receipts. I recently noticed that the driver side seat heating and cooling doesn't work right, passenger seat works fine. I haven't checked the fuses yet just wanted to get some opinions before getting into it.

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 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?

OK Wife has been coming home and the car smells like coolant. The tiny hose from the rad cap to the reservoir isn't pressurized and popping the res cap does not release pressure. Do they are supposed to pressurized?
The coolant level is in the exact middle of high and low just after a 25 minute highway drive. I cant see any puddles or leaks anywhere on the tray; but I have pulled the tray anyway to see if leaks show up on my floor. Temp gauge never wavers at all from what she tells me.
This is a bit perplexing. Maybe a bad rad cap?

2006 sonata gl with 4-cyl engine. Car runs/feels fine. Installed HID kit a while ago (with harness) and no problem. Driving home late afternoon (with AC on hi) stopped on red light. Radio was on but NO HID lights on - then momentarily car stalls. Starts back up right a way and NO check engine light. Tried AC- works fine, turn the lights on (HID 35w slim balast), radio on - everything is fine.
My "suspect" is old battery (original!) and I think that for a short moment charging system (alternator) could not keep up/charge battery while car was idling with AC and radio on (hi load).
How long is original battery good for (5-6-...yrs)? Looked earlier at Everstart batteries (or was it Eveready brand?) made by Johnson. I could only find a few batteries but they were sitting on the shelf since last summer (sticker said made 07/2010 !). Are they any good?

Usually in the morning after starting the car, when I put the car into reverse the car stalls. I start it up again and it works fine. It has been doing this for a few months. When I went to get oil change they said I needed to replace battery so I did. Problem is still there. It has done this twice when I try to take off from a red light. I have no check engine lights either. My car has 105,000 miles but cannot really afford to buy a new car at the moment.

I have an '09 Accent, with 102,000 miles on it, it is in good shape, and current on all its maintenance, however, i am leaking coolant via the radiator cap, and don't know why. It has been replaced twice, once by me, and once at the dealership after a pressure check confirmed i was not leaking anywhere else, ie: into the engine.

I have a question regarding my 06 Passat 2.0.
This morning I started up the car and immediately the car has a coolant light on in the top row of the MFD (thermometer in a few little waves, I assume coolant.)
Temperatures dropped below -10F last night and were about -4F when the car was started. My thought was a freeze plug, but no AF puddle when I parked the car and the AF level in the overflow tank was where it was the last time I checked. It's cold enough the car never reached the normal operating temp during 20 mins or so of city driving.
Am I correct in assuming this is a coolant level warning? I can't imagine I'd be getting a temperature warning when the block is 0F.

I would like to be able to use the fan to bring in outside air with no heating or cooling. What I have been doing is turning the temp setting to Low and controlling the Fan Speed manually.
This seems to work unless the outside temp is too low, then it seems to be heating the air a bit, which I don't work. Is there a different way of doing this? I feel like I am missing something.

It was the first really cold day since I got my car--40 degrees F. outside. I hit the Auto button and bumped the temperature up to 78 degrees. The A/C light came on. I tried turning the system off and then on (now that the temperature is set higher), and I got the same thing: the A/C light came on.
Is this normal or should I have this looked at next time I take my car in for service?

Is this normal for the GS300 to loose anti-freeze coolant in its reservoir? My 2006 GS300 had little coolant in the reservoir on Monday and I took it to my local Toyota dealer to check it out. They recommended me to do a flushing instead of draining and filling for the coolant since the previous owner never changed it. I did the flushing and they put it Toyota SLLC (pink) coolant as well as filling up the reservoir to full mark. Today I check the reservoir again and it is 1" lower. Is this normal? I check the radiator, engine, hoses but I did not see any leak. The temperature is fine, no overheating or anything.
