Elantra XD (2001-06) :: Heater Not Providing Hot Air / Radiator Hose Leaking
Jan 13, 2013
I have been encountering issues with my heater not providing hot air when the engine is idling. My Elantra has around 121K miles on it. I have not replaced the thermostat, water pump, timing belt, radiator, radiator hoses, or done any coolant flushes.
I checked the overflow reservoir and radiator. I didn't see coolant at top of the radiator so I topped it off as well as the reservoir. It seemed to have fixed the issue for now but I had this similar issue about 5-6 months back. I also topped off the coolant and things have been fine until now.
I checked the hoses and squeezed them to see if I could see any notable leaks but didn't see anything. I checked the overflow reservoir tank and line and nothing seemed out of the ordinary. I also checked the top of radiator to visually inspect for any notable cracks but didn't find anything. Also to note, the coolant inside the overflow bottle was bright green and not discolored.
I did however notice a lot of white chalky residue on the bypass hose below the upper radiator hose and the engine block. My guess is that my upper radiator hose is slowly leaking? Leaking in the thermostat assembly? And I also noticed a tiny puddle of coolant below the lower radiator hose at the engine block. See the pics below.

2001 F250- V10... Lower radiator hose has coolant leaking - Right now I cannot tell if its the hose or the radiator itself (hoping not) - I tried to take the clamp off and it broke - Any tricks to removing the hose? its on there pretty tight.... I guess if I don't want to save the hose I can rip it off with a pair of pliers but before I do that wasn't sure.

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.

I have 98 passat V6 and the lover radiator hose is leaking at the connector between radiator and the hose. Do I need to change the whole hose or is there maybe an o-ring that should be changed? How hard is to remove the hose? Do I have to go to the dealer?

After chasing the smell of coolant for a couple weeks, discovered that the upper radiator hose was leaking at the engine. Based on my schedule and drive schedule, and unfamiliar location this last week, I took my truck to the last people I wanted to - the Ford dealer, where they attempted to charge for the hose replacement. During this time I discovered the nature of how these hoses work and asked the tech why they don't just replace the O-rings ... "Ford Motor Company wants to sell you a new hose with labor" - a direct quote from the Ford tech. And that is why Ford is the LAST place I want to go for repairs I cannot perform. I kept the old hose - any spot where you can get the O-rings alone?

This is strange, Had the truck for about 3000mi bought it at 147k now has 150... Any way it runs great but the radiator started leaking from the seam close to where the bottom hose is. I have since changed the radiator about a week ago 500mi a week work truck.
Now it seems to be leaking from the very same area, what I mean is the area around the hose is dry but just up the seam a bit it barely leaks, and mainly after the truck cools off at night. These radiators seem extremely low quality, is there a substitute higher quality.
Also of note mine is the 1" core, I was told there are others but they will not fit, I must agree it seems nothing else would fit due to space constraints. These radiators just kinda sit in a cradle and aren't really under any stress that I can tell so it doesn't seem as though that would be the cause.
Also of note the shop where I bought the new one took it out of the sealed box and tank pressure tested it as they do for all new sales, no leaks, I have not pulled it back out yet cause I would like to get some thing less flimsy if it exists.

The leak looked like it was coming from a heater hose. The individual I bought it from said he fixed it and it wasn't leaking the day I bought it. Upon driving it home...cranked the heat up and windows fogged, switched to defog with no luck. Added some coolant and still the same thing and leak began again.
It smells like antifreeze inside and fog has oily feeling when wiping it off the window. Got in on the lift and no luck seeing where it was leaking from, even with it running. My previous experience with bad heater cores is that it leaks on the inside and smells like coolant... is it leaking on the outside or is it something else?
It's NOT overheating or blowing any kind of smoke. Temp gauge read normal! It's a 4.3L, 1994 Caprice LS .....

Found a tee on the heater hose leaks when it warms up. Appears the PO had noticed it but put a hose over it and now is leaking around behind the valve cover. This is a hard plastic line around 5/16. No online parts show it as being available. Is there a fix for this ?
I would bet several others have had this problem as it lays right on top of the flange of the valve cover where I think it would rub a hole pretty quick.

On the manifold there is a metal/steel pipe that the heater hose hooks to. That pipe is leaking anitifreeze. It has a small hole in it. Is this pipe replaceable or is it part of the manifold.

I've noticed that my radiator hose doesn't have any pressure anymore, even after a long drive you can squeeze it nearly together, it is still hot like normal and the heater puts out hot air, the temperature gauge sits between half way between 1/4 and 1/2, would this be the radiator it's self, the thermostat or the water pump that may need replacing, there is no leaks that I can find or see...

A couple weeks ago I had my first oil change - not at the dealer - but at a place I've gone a hundred times. After I noticed every day a puddle, not a couple drops but a puddle going down my driveway or wherever I parked of water.
I thought for a few days it was condensation off the engine, or the AC, since it was very hot. Except I don't use the AC much & wasn't using it when the water was leaking. I looked under the car & there is a hose hanging from the back of the engine area & dripping water.
I've honestly never looked under the car & noticed the hose & it's only hanging about an inch - so I'm not sure I've just never noticed... But until the oil change there was never a noticeable water leak..

2001 12v vr6 here, found my leak, now I need to know what the heck this is! Is this even removable?! It's basically a plastic elbow that connects to the radiator on the driver side, I have a photo. I tried fixing this crack with some glue and tape (It was late and couldn't get any temperature friendly glue), as you can see in the picture, it's covered in electric tape, and the hot coolant burned right through it all.
Another problem I had is my fuse box, burning through my fan fuse, looks something like this, the fuse was burned, but after placing a new fuse (just for contact), the fan worked, so I'm guessing a new fuse box is where to start ?

I have replaced a head gasket on my 2001 civic LX recently. I have drain the coolant and put it back on again. Now I have idle issues, the car starts fine with high RPM (because it is cold) about 5 min latter the RPM changes, it revs low and high (about 2000 rpm) when it should be idling normally. I have taken the radiator cap (before i start the engine) and run it a while with the cap off to purge any air pockets, no luck. Another thing I have realized that there is a pressure build up in the upper and lower radiator hoses when it is running with the radiator cap on. How to fix this problem?

I've got a pretty substantial drip someplace at the vacuum heater valve and I am trying to figure out what I am dealing with. I replaced the valve and clamps but the leak persists. The three hoses are so close together I cannot tell which one is leaking.
What are the part numbers for the three hoses? There is one that runs from the intake/front passenger head to the valve that is just held on with clamps. One runs straight down to some sort of fitting and connects to a metal line. I think it may be a quick connect fitting. It is very short.
The third runs from the back of the valve to the firewall.
There is a fourth hose that comes back up from the "somewhere" below and also is a metal hard line with a fitting and rubber hose that goes "someplace" else back towards the firewall. Not connected to vacuum valve...
In any event, if I am going to rip into this, I'd like to just replace the hoses in one shot and done with it. No luck finding much on Google.
The 2 pics included show the valve and the front heater hose. ( I saved the OEM clamps by just sliding them back on the hoses as pictured. I figured if the valve and worm drive clamps didn't fix this I'd put them back on.)

I'm pretty sure I have a blown head gasket. I have white smoke coming out of exhaust and the oil is brownish in color indicating radiator fluid is leaking into engine. The car has over 200K on it. I purchased Steel Seal. The guy I talked to from Steel Seal said if radiator fluid is dirty (which it is)than I should flush radiator before using product. I don't have money to replace the gasket and I don't have money for a new car right now. Can this be a fix that gets me through a couple months?

At 145k my radiator seems to be leaking. Eventually I'll be at the point where heat blows ice cold. Where should I get a radiator?

Went to start my truck to leave work yesterday and blew the coil on #2. It's happened before and I can fix that. The other weird thing that happened was that the radiator leaked out some antifreeze. Not a lot, but a good 2 foot puddle. The reserve was still full and it leaked from the passenger side at the bottom (below the upper hose). Upper and lower hose show no sign of leakage. I suppose the drain is on the lower end of the passenger side of the radiator and it leaked from there. Would the compression from the engine cause that to happen? Or is it something more, dare I say, like the head gasket blew?

I bought my car last May and never noticed the radiator fans running, but over the past couple of months they've been coming on (or at least running at a higher speed) pretty much every time I take it for a longer drive. They appear to come on only when I'm idling and turn off when I start moving again. The temperature gauge is steady at just below halfway. I'm certain this didn't happen previously, or if it did the fans were at a low enough speed that I didn't hear them. In my inexperience I would have thought they'd be less likely to run in the winter, and we've been having continuously cold weather (<30 C).

I had recently blew a head gasket on this car due to my radiator cracking and i have had it fixed and it does not over heat nor does it leak water. and i honestly without exaggeration have changed about every censor on that car besides the mass airflow but i am currently having a problem when i accelerate it kind of chugs but does not die. it does not do this when i just idle forward or when i have the gas pressed lets say on a scale from 1-10 it would only chug when I am at like a 1-2 at most then after that its great no problems.

The problem started when his heater core was leaking coolant and it dripped all the way down to his original ECU. Car stopped working. Then he went to a Hyundai dealer to fix the problem but they said he had to buy a brand new one. First ECU didn't work. Returned it and bought one more expensive. Dad told me it worked but he didn't by pass the heater core so coolant dripped again. So now I'm on my third ECU but it doesn't work. I've read online that some older cars have plug-and-play type of ECUs that aren't restricted to the VINs. His car is a 2004 Hyundai Santa Fe GLS FWD 4dr 3.5L.

My 06 Elantra with 115K miles on it broke down in the middle of the road on Thursday. The smoke was coming from under the hood. Towed it in to a Hyundai dealer, they looked at it on Friday and told me I needed a new radiator, the old one cracked at the upper seam line (whatever that means). I told them to go ahead with replacing a radiator, which they did. Today, Saturday morning, same problem, the car is blowing smoke from under the hood, spilling the coolant on the road. Towed it back to the dealer again. They say that the new radiator broke down, it cracked in the same spot as the last one and they're trying to figure out what's going on. Haven't heard from them again today and they're closed right now. I hope they will fix it on Monday. What might be causing this problem? Are there any other parts that might be causing the radiator to break like this? Is this a common problem for Elantra XD?
