Elantra XD (2001-06) :: 2005 Hyundai GT - No Coolant Leak But Overheating
Jul 15, 2016
I have a 2005 Hyundai Elantra GT Hatchback, and it is not going so well with me at the moment. My thermostat works perfectly fine, but my car is overheating. I've taken it to the shop multiple times but still doesn't seem to get fixed. My coolant seems to be fine, and stays at its level, but what doesn't seem to be fine is that it doesn't seem to be sucking strong enough into the radiator so that it can go to the engine! On the lower level coolant cap (one with the hose attached), it seems to be leaking out of there when the car is hot, as if the coolant is trying to suck into the radiator but not strong enough but yet leaks out of it since it isn't strong enough. My theory is, the cap with the hose isn't on tight enough to fully let the coolant suck through the hose, and so air leaks cause the coolant to leak out of it and not into the radiator.

2005 Hyundai Tiburon Keeps Overheating
I live in Washington State and have a 2005 Hyundai Tiburon with less than 110,000 miles. I have had it for 5 years, and have not had any issues with the car until recently (last 2-3 months). My car overheated on me back in May while out running work related errands. I was able to leave it parked downtown while my husband took a break from his job to come pick me up. Since then, it has continued to overheat every time I drive it.
The temperature gauge climbs into, or dangerously close to, the “red Zone” within the first 10 minutes of driving. The first couple of times the car overheated, if I was using the air conditioner, it would start blowing hot air instead of cold air and the air would stay hot. Now when I drive the car with the air conditioner on and it over heats, it continues to blow cold air (if that matters at all).
My super handy husband (a certified motorcycle mechanic) has done the following in an attempt to fix the car:
•Checked coolant levels
•Topped off coolant
•Bled coolant system and added yet more coolant
•Replaced the thermostat
•Replaced the radiator cap
•Water pump was replaced November 2012 (not even a year old yet)
The radiator cap was the most recent fix. It was replaced on a Wednesday evening after testing it and finding that the existing one was not maintaining the proper PSI. The car drove great around town for two whole days without any issues (Thursday & Friday). Saturday, I decided to take it on a longer drive out of town to see if my good luck would hold…it didn’t. I drove a total of 30 miles round trip and my car started overheating after about 20. I limped back into town and barely made it back to our apartment.
My car continues to overheat!! What is going on?! So confused and frustrated I’m hesitant about taking it to a mechanic who, my husband is convinced, will just charge me to check all of the things he has already fixed.

I own a 2005 Hyundai Elantra with the standard 4 banger. About 6 months ago I noticed coolant residue on the mid steam hose. I removed the radiator cap and I didn't have any coolant at the top. So I topped it up and found that the High side had pressure and the low side not so much. So I brought it in and the the Thermostat and hoses replaced. That should have solved it. 3 months later I opened the hood and noticed coolant on the Clutch actuator and the divots in the trany casing. So I took it in again.
The mech said it was a slit in the lower rose. making an air pocket. Ok so they drained the coolant and replaced the hose. Two weeks later same story. The high end gets hot the low end is leaking (dibbling) out the engine end of the low side hose. I brought it to another mech and they checked the flow (good) pressure tested the system and head gasket(good). In short, they found nothing wrong. Thermostat opens fine everything is good. Except...... I am still finding coolant dibble on the trany case. Its not a major leak - about half a pint per week- but its annoying as hell.

I have a pretty bad oil leak from front valve cover but whats odd is that it suddenly stopped showing low on my dip stick. Now it ALWAYS says a quart overfull no matter how much oil is leaking out. Also after driving for awhile it gets a terrible knock. There is no smoke however and engine runs like normal.
The car is a 2005 Hyundai Elantra.

Today, the air conditioning stopped working in my 2003 Elantra. Just stopped blowing cold air. Then the engine thermometer kept on climbing. When I pulled over home, I lifted the hood and heard a lot of bubbling and gurgling sounds, and coolant fluid leaked out underneath the car.
What could be the cause of this? When I let the car stay for a while, the AC did kick back on, but only for a few moments and the thermometer kept on climbing again until I turned the car off. The fan is blowing, I can hear it, but it is obviously not cooling the engine off appropriately.

My Girlfriends car over last night, i went and picked her up and found the radiator caps was not on right and the electric fan was unplugged. Fixed both of the those and got about 10 miles and the car still over heats only while under throttle. I pull over and park it starts cooling down. turn on heat seems to work for a moment but it never blows warm air. The check engine light came on and i have got the code P0117, Engine Coolant Temp, circuit low input.

My wifes 2002 gls has a coolant leak from the top radiator hose. I put a new hose on and two new clamps on the leaking end and it still leaks!! I have never seen anything like this and I am not sure how to stop it.

My daughters 2005 Hyundai Elantra has 77,000 miles om it. Just changed the wires and plugs, new brakes. Now, it runs very rough when stopped at a light and it is in gear. Now, when she has the AC running, and she stops at a stoplight, she has to put it in neutral or the engine will almost but not quite kill.

I replaced my Radiator, Upper and Lower Hoses, Thermostat and the thermostat gasket yesterday. I am leaking coolant from the thermostat though, It's coming from the seal between the housing and the block. The gasket was brand new and seemed to fit fine. I don't see any damage around where the seal is made..
Going to run and get a new gasket when the store opens.

I recently purchased a 2005 Elantra GLS. It is super clean and runs great. The dealer replaced the original radiator and hoses because they said the original radiator had a hole in it. After driving the car, the engine compartment has a coolant smell. No smell in the cabin. I looked everywhere but don't see any signs of a leak. There is no smoke coming from the exhaust and the oil is clean. Coolant levels in the over flow tank and radiator are good. The car is only driven short distances (maybe 100 miles per week). What could be causing the coolant smell in the engine compartment?

Our Elantra never overheats or shows hot on the gauge but every couple months it is a little low on coolant. When I shut it down I sometimes get the sweet antifreeze smell. I see no leaks. Never a spot on the driveway. Just need to add a little. Car has about 80,000 miles. as a matter of annual maintenance I drain and fill the coolant and trans fluid once a year. Hoses are in good shape. The oil is clean and shows now sign of contamination. We Love this little car.

I purchased a used 2005 Elantra two weeks ago. In the last two days, it began spraying oil at high RPMs. The oil pools on top of the transaxle (driver-side engine compartment), and down the front of the engine onto the exhaust manifold, giving burning smell and smoke. Trying to find where it was coming from, I cleaned everything thoroughly, but I can't locate the leak/spray. If I drive under 3500 RPM, no oil sprays or accumulates. Over that, it does. Oil filter was tight (first thing I checked), can't find any obviously loose fittings or bolts. Where this may be coming from, or should I just bite the bullet and go to the dealer for diagnosis?

Our 05 Elantra (170k miles) is leaking coolant externally from the head gasket. At first I thought it was coming from the freeze plugs, but it's actually leaking from above. I'm mechanically inclined but have no experience with head gaskets. I have access to Alldata but no service manual. Will it tell me everything I need to know? The farthest I've gone inside an engine is removing valve covers car runs great and we like it enough to want to keep it for a while ... I'll also mention I will be replacing the timing belt as well.

Ok I have a friend with this car and said it kept over heating. I went and looked at it and found the source of the leak. It's right after the heater core. The hose comes out and into the engine. Where the hose slides onto the engine has a leak . It looks like the piece can unscrew and be replaced but I don't know what it's called.

I noticed my 2002 Camry XLE was overheating and discovered that I had lost a lot of coolant. I topped off the radiator with pink 50/50 and went for a little drive, after parking I noticed a slow coolant drip that would eventually stop.
I took it into a shop, and they did a pressure test and found the leak was from SOMEWHERE behind the intake manifold. They also told me that it may be a "common" problem in my year that the threads in the cylinder block are pulling out, causing the cylinder head to lift and coolant to leak. They claim that they have to pull of the the valve cover gasket and inspect the torque for the headbolts, if they're loose I'd need to replace the engine block (!!!)
My thoughts are that it must be coming from somewhere near the intake manifold. I just had it replaced five months ago and am thinking something went wrong in the process.
I guess my questions are, is the bolt loosening thing legit? I'm not burning off coolant (have checked exhaust and it's clean, not white or anything). And what if anything could have gone wrong in replacing the intake manifold to cause said leak?

My 04' GTI, 24v VR6, all stock, @ 107,000. I had a coolant leak from the t-stat housing. I installed all new housing, seals, and C-Pipe from GruvenParts. Already had a green CT sensor installed and the kit I got didn't come with one, so I didn't change it. Found out the leak was from the t-stat housing o-ring didn't fit the old housing. The new one fits perfect. I put coolant on the seals and burped it. Doesn't leak a drop. But still overheating, all the hoses have pressure and are hot, so no blockage....I noticed the fans were not coming on at all. The fans used to engage every other minute and run for 15 secs on high ONLY. Longer times, if not constantly w/ A/C on. I was wondering how to test the fans, sender, and/or fan control module to see which one of them isn't working. And which pinouts are what?

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?

I've been driving a 2006 Liberty with 110,000 miles and have had no problems for about 6 months. I didn't get a tune up at the behest of the previous owner who had showed me records of the last time he had it tuned up. I didn't notice that he hadn't flushed the radiator, however. Since the cold weather started, I've been very cautious and making sure not to cold start. On my way home from work, I was stopped at a red light, started to accelerate and heard and felt a POP that felt like the transmission slipping or something to that extent.
I noticed the car started to overheat. I pulled over, and being the rushing idiot that I am, I decided to open the radiator cap. I didn't hurt myself but coolant leaked everywhere and along with it were chunks of rust. I had a lot of trouble turning it over to get it home but ended up doing so and it didn't seem to run any worse, sans the overheating and cloud of coolant. I'm so nervous to take it to a mechanic and see the monetary damage. From the description, what I'll be in for? Did I damage it further by repeatedly trying to turn it over??

My poor old jeep is having some issues. Here's the stats: 94, 4.0 engine, 240k miles (jeeps am I right?). It started overheating on me so I start with replacing the thermostat. No dice. I noticed it was "weeping" coolant, so I replaced the water pump. No dice. It's still running hot and throughout the process of replacing things and test driving it is now struggling on accelerating/giving it gas to switch gears. It even out right died a couple times. (Air filter was gunky, replaced it.

Have a 2000 subaru outback 2.5l, automatic, with about 245k, I replaced the thermostat,water pump, the radiator and the car is still overheating. both fans are working. no leaking coolant. Maybe this is related- over heats mostly when driving on the highway. But if a shift the gear to neutral and coast for a minute the shift back to drive the temperature gauge goes down. Whats wrong, running out money fixing the car, but love it driving it in the snow.

So a couple weeks back I'm on expressway home and I look down and and temp gauge is pegged out overheating I immediately pulled off and shut it down and towed to a buddy of mine's shop he flushed it filled it up w antifreeze and checked for leaks and couldn't find one. I drove it for about a week and got out to for a quick stop , Ex parked on a slight decline and came out to prolly half gallon of coolant on the ground..I limped it to my buddies shop as it was not running hot .. he has checked it out but can't find any leaks, even after having it run 30 or so minutes..
