Elantra XD (2001-06) :: 2005 Coolant Low - Antifreeze Smell When Shut It Down
Nov 22, 2013
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 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?

This is my second vw I've owned and now I own a 20th ae gti. Just the other day I got out of my car and smelled antifreeze. So I popped the hood and realized there was no coolant in the reservoir.. So I went to my dealership, put some in... well that obviously isn't my problem, because the next day it was gone. Again. This is on sunday so I can't do anything about it. I made an appt to drop it off tonight @ my volkswagen dealer. It's not leaking, not smoking or burning, and the temp gauge isn't moving at all.

My 2005 chevy silverado 1/2 ton seems to be low a quart of coolant every 2-3 months. First alerted to this during a oil change, check it monthly and need to add a little to the reservoir every other month. The temp gauge never goes over half way. I do smell antifreeze after I shut the truck down after a significant drive, but only if I walk to the front of the vehicle.

The last couple of days I thought I smelled antifreeze and I had to add about a pint of coolant to the reservoir. So I looked all around today and can't see anything leaking. Nothing on the floor. I suspected the water pump but looked pretty dry from what I could see. Thing is if its the pump, its still under warranty for a few months and 7,000 miles so want to find that pretty quick. Radiator is fairly new also from hitting a coon. Any tips? Not sure if a pressure test would detect a small or intermittent leak in the pump though.

Son in law just bought a 2002 Explorer with the 4.0. Looks in pretty good shape and overall I don't think he got a bad deal. However....after a test drive I noticed an antifreeze smell. Got to poking around and it appears to be leaking directly below the thermostat housing and that whole manifold for lack of a better word. It's a bugger to get in there and really see what's leaking...doesn't appear to be any hoses but given the angle can't be really sure. I'm new to the Explorer and the 4.0. Is this anything peculiar to the Explorer/4.0? A known part problem? Something far worse?

My 2005 Elentra GLS, when I use the key remote control and hit the alarm activation button, the alarm goes off and lights flash. And I haven't even opened a door on the vehicle. I am not using the alarm function because of this issue. Is this something I can troubleshoot. Just purchased the car used from a used car dealer.

I smell gas when I start my vehicle. However, the smell goes away once the car warms up. Is this a concern?

I have a 2011 Elantra Limited. No nav. I really like it. But I often smell the sweet smell of hot anti freeze/coolant coming from the engine area. I see no visible signs of anything wrong. My past experiences with this smell usually indicated overheating or a leak.

My girlfriend has a 2005 Accent and recently we went to go drive it and the battery was dead. I noticed that when we shut the car off the black LCD Odometer display was staying on the dash with the power shut off and no key in the ignition. I figured out which Fuse it was under the hood and pulled it. The odometer lcd turned off and we also lost all of the interior lights.. When I ran the car with the fuse pulled the Odometer LCD would display normally but somehow the battery is still managing to drain even with the Fuse pulled.. Any wiring diagrams for the fuse panel under the hood or if it could be a relay that is still drawing power when the car is shut off..

Brand new 2012 LS460 with one Dealer oil change:
This one started with stronger smell on passenger side but is now strong hot antifreeze smell when you open either front door. Not a drop on floor, no gauge movement from normal on hot 2-3hr trips - Only had one service six months ago at dealer just because it was to sit all year. I pulled all top engine covers off to inspect and found not one thing wet or suspect.
Ready to put on rack to look underneath (below firewall I suppose) just not sure at what, heater core connections? But a head gasket would be 1st guess? What could this be?
SAME as previous post (but no ID) from a 2008L owner: "I only have about 3,500 miles on my car, every now and then I get a faint smell of possibly antifreeze when I open either of the front doors after a good drive. It's very strange because if I try to locate the source, the smell goes away. Once I exit the car and sniff around, there is no smell in the wheel wells, in the front grill, or under the hood. I then try to sniff under the car just under the front doors, and there is no smell!"

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.

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.

2002 Santa Fe with 140K. Superbly well maintained.
I notice . Looked all around....then on the radiator toward the top where the metal meets the plastic. I noticed wetness across the entire radiator. Thought it may be coming from the upper hose and spreading across....Replaced the upper hose....Not the problem.
Still has anti freeze seeping across the radiator / plastic area. Does the mean the entire radiator needs replacing? I have searched the forums and seems like no one had replaced a radiator on the Santa.
Is the radiator breaking down. Oh, it's NOT the water pump.

I have a 2004 Hyundai Santa Fe with a 3.5L engine and 92,000 miles.
For the past week or so, I have noticed a very slight smell of antifreeze/radiator fluid every once in a while. I assumed that it is a radiator hose leak or possibly a leak in the heater core. But, the vehicle does not overheat, there is no steam or fog inside that would indicate a possible heater core leak, and the radiator fluid level seemed full or almost full (although the radiator overflow container was empty). I added a little water to the radiator and filled the overflow container to make sure there was plenty of radiator fluid in the system.
I haven't seen any radiator fluid on the ground around the vehicle at anytime. When I open the hood, I don't see any leaking hoses. I took off the engine cover to see better, and I don't see any leak around the water pump, or dripping from the pump, or dripping from any hoses, etc. But, BELOW the water pump is something made of cast metal that I am guessing is the automatic transmission(?) -- I really don't know what it is. And, sitting in some valleys or crevices in that part are small pools of green fluid that clearly looks and smells like radiator fluid with antifreeze.
I ran the vehicle for a long time while watching to see if I could create or see the leak or anything dripping etc. But I don't see anything other than
those pools of green liquid just sitting there. I tried moving or wiggling the hoses, and nothing changed. I also tried keeping it running with the heat on high, then later with the AC on high -- still no change. Then I tried using paper towels and sopping up what I could that was in these valleys/crevices, then I drove it again (but only for about 4 miles so far) and I don't see any new fluid in the crevices or anywhere else.
Here are 5 photos that I took with the engine cover off while the green fluid was still there. The photos go from a wider angle overall view down to a view of the green puddles from a slight angle and then down to a top view of the green puddles.

Where you may see dark areas on the water hoses near the water pump, they are just shadows created by the flash or the sun or whatever. The hoses themselves are all one color and are not wet etc.
My questions:
Am I correct that where the small green puddles are is the automatic transmission?
Is it possible that there is some connection between that (the automatic transmission(?)) and the radiator cooling system?
Is it possible that the cooling system somehow also cools the automatic transmission (or whatever that is)?
If so, could the leak be right there -- maybe where that bolt or the other wire/connection piece is -- and the radiator fluid is coming UP from there? What this may be or where the leak is coming from?

I have a Hyundai Elantra 2001 that I just bought off someone. I've had the car maybe 2 weeks, I changed the radiator because it overheated last week. Then, I found out the valve cover was cracked in four places, I replaced those too... I bought and installed a new thermostat, and I thought that would be the end of overheating... I was wrong, last night I felt like I smelled antifreeze strongly, so I parked it and this morning before heading home from work, I checked the radiator, it was empty. I filled it with antifreeze, and headed home, 20 minutes later, I parked on my drive and see that I have a huge leak... and it's antifreeze.
So, seems like I had left the cap open somehow, I didn't close it all the way. That was understandable, so I put some more coolant in it, and took off in the afternoon - 20 minutes into my drive, it starts slowly overheating, I see the gauge going up so I pull over, as soon as I do the car shuts off. I took the keys off the ignition and opened the hood. Now, there's smoke coming off the engine (smoke came from under the valve covers). I gave it 20 minutes rest at least, then added water in the radiator. Turned it on and it worked ok for about 5 minutes, I drove 2 hours to get it home at this rate, stopping every so often. Then, got it home and parked it.

I am looking at a 05 GLI 5 speed with 133k miles. I drove it yesterday and it runs fine, but I smelled coolant after I turned it off. I was told by the dealer that the turbo is leaking some, it was spooling while driving and didn't seem to do anything funny. The check engine light came on and said coolant was low when we got back, when I cranked it back up the light was out. Just not sure about it.

So I noticed the smell of burning coolant a day after I got an oil change. My car wasn't overheating and my thermostat didn't jump at all. I open the hood and there's a little bit of smoke. I take it to a mechanic and they do a pressure check. They see dried coolant under the upper hose connecting the engine to the radiator. They tell me its the flange connecting that hose to the engine that's leaking low levels of coolant and it will cost 150 to fix.(not a gasket) I say go ahead. They're in the process of fixing it today and they call me saying "We got the part, and we're going to fix it but we think the thermostat isn't fully opening or closing which is causing the problem and it will be another 150 to fix". Now I looked up this mechanic and they have 12 1 star reviews on Yelp of people saying they were overpriced and the mechanics often piled on things once they got on.
My issue is essentially the mechanic said "This problem could happen again if you don't replace the thermostat" but he also said they're not sure if its a bad thermostat. Couldn't they check the thermostat easily??? Like I said I said besides the leak in the flange I haven't had any issues. The car warms up fine and the temperature NEVER spikes (I had a different car overheat and blow a gasket two years ago cause I didn't notice the temp gauge for 2 miles and I LEARNED MY LESSON) I always keep a careful eye on the gauge.
My question is isn't there an easy way to check the thermostat? The mechanic keeps pressuring me to fix it. Just to be safe I am just having them fix the flange and taking it to a mechanic I trust. (I couldn't take it to him before cause he's on the other side of town and I was paranoid my car wouldn't make it)

I have an 01 supercab. 5.4 Triton 135k. I have begun to smell coolant the last couple of days. Have seen nothing leaking and truck doesn't run hot.
Will investigate more this weekend. Where to start looking for this. It has to be leaking somewhere. Windows don't fog and the smell is there all the time. I live in florida so don't use much heat.
Not the heater core. Heat works fine and no smell from the vents.

First time I've filled the car up and getting a gas smell while driving. I checked the gas cap and it's on.
