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...
View 5 RepliesI 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?
View 13 Repliesthis winter i have found that my truck's heater core isn't flowing, meaning i have hot on the upper hose and the lower is luke warm and there is no heat while running down the road. I have changed the t-stat and the heater core and radiator are new as of four years ago. last year i could roast a chicken with the heat. i also have no pressure in the radiator hose at all, engine runs at normal temp, no over heat situation and i don't smell any loss of antifreeze.

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.
View 3 RepliesI 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.
View 2 Replies2001 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 ?
2001 F150 Supercrew 5.4L ... Dealership unable to locate replacement pressure hose for power steering . I've returned 3 wrong parts. The hose in pic goes all the way up to the reservoir.
View 13 RepliesThe wife was out in the Fe yesterday(2001 2.7 V6 Auto AWD) running at highway speed 80kmh before pulling up to a junction, when she pulled off again then the car came to a halt and lost all drive with engine still running ok. Luckily wife has the sense to switch it off. Tow trucked it home after she saw a puddle of tranny fluid under the car.
Any way it turned out one of the transmission hoses running from the cooler (right hand side hose that runs under radiator) managed to blow off the metal pipe.. don't know how, oem clamp was on and hose didn't split just came off! Needless to say this resulted in the tranny fluid quickly being emptied all over the engine bay and no gears.
So ive re attached the hose with new clamp and have drained what fluid was left in the pan..about 1 liter, and need to fill it up now and find out if it still works ok.
Now the manual says it needs 8.9ltr for a full fill but the question is will it of emptied the torque convertor as well so its completely empty or will it just of blown out the contents of the pan before stopping then just needing half fill.
What could cause a hose to blow off, they don't run at that high pressure normally, average hose pressure is normally 35-55psi from what I can find out so shouldn't blow off that easy should it.
I have a 2006 2.7 gls awd santa fe ,the alternator bearing went bad and got stuck took the alternator to a repair shop to get fixed, put it back on the santa fe the alternator worked just fine now i have the radiator fan and ac fan not working, I turn the ac on and none of then work I wait for the car to heat up and nothing happens I check the radiator fan by connecting it directly to the battery and it works fine ,i have swap the horn relay with the radiator relay and it is working fine. I will check net the fuses, then the thermostat and later on the temperature sensor.
View 29 RepliesMy daughters radiator fan would not turn on, and I isolated it to this connector that connects the radiator fan to the wiring harness. The problem is that I've tried for a hour trying to unplug the darn thing, but it won't come apart. I've opened the two covers on each side and see the burnt wire, but I've been pinching the little pincher thingy and pulling and it won't come apart. I see Hyundai has a replacement connector (91200-26000-fff) but the dealers are now closed till Tuesday. Need to get it apart & is replacing with another connector from an auto parts store advised?
View 3 RepliesI checked the coolant level on the reservoir and it was low.
I decided to add coolant by removing the radiator pressure cap, however, the coolant fluid is full under this cap.
So my question is where should I add coolant? through this cap or the reservoir?
Today I noticed my 2003 santa fe was leaking coolant. I got under it and noticed it was coming from a small red cap under the radiator on the driver side. I figured it was the drain cap. It's kinda hidden so it will be hard to remove and replace so any tips on how to do this.
View 4 RepliesMy 2005 Santa Fe, 2.7 liter, automatic, FWD. with 180K miles had a cracked radiator. The leak is in the front of the radiator about 6 inches right of the filler neck (as you stand looking at the front of the car).
I've found an OEM replacement radiator and looking to replace this weekend.
I can see I need to remove most of the front grill and support, drain the radiator, move some parts out of the way and disconnect to hoses and fan electrical leads. Is there anything else I'm missing? Is there a good write-up on a radiator change that I'm missing?
So a few days ago, I decided to check the anti-freeze for adequacy. It was just replaced with the timing belt / water pump job; but I'm a pilot, and I'm accustomed to checking things for myself. Lo and behold, the hydrometer didn't even register. I thought it was stuck, but then I noticed the oily film, and got scared. And then as I investigated further, I got puzzled.
The car had been driven maybe 500 miles since the timing belt / water pump job, had not overheated, and had not lost any coolant. The level in the radiator was up to the cap. Also, there was no oil at all in the radiator (at least that I could detect), and the concentration tested fine. But there was oil in the reservoir -- but it didn't look like crankcase oil. It was clear -- like water -- and felt a bit thinner than crankcase oil. Also, the outlet at the bottom of the reservoir was clogged.
There also was some sealant in the reservoir (it looked like the BarsLeak tablets), but none that I could detect in the radiator. That in itself doesn't bother me because a lot of people (including me) routinely toss a few tablets in the coolant -- Saturn used to do it from the factory -- but it does suggest at least the possibility of a previous coolant leak that someone treated with BarsLeak.
At the moment, there's no evidence of coolant loss, no water in the exhaust, no water in the oil, and no oil in the radiator. I haven't done a compression test. I did change the plugs, and there were no obvious coolant deposits on them. They were carbon-fouled, but considering that the PCV valve was clogged and the mileage on the plugs, that didn't surprise me.
So what I'm postulating is that the previous owner's son (who was the primary driver of the car) mistakenly poured some sort of engine oil additive, power steering additive, or something else intended for use elsewhere, into the reservoir; and the mechanic who did the timing belt and water pump didn't notice it (which also kind of bothers me).
The fact that the power steering pump had a bit of chatter would tend to reinforce that hypothesis. I've been doing a gradual replacement of the power steering fluid, which seems to have quieted things down. It was black as tar when I started, so I probably should completely replace it. I may do that this coming weekend. In any case, I removed, cleaned, and unclogged the coolant reservoir, replaced it, refilled it, and everything seems fine. It's kind of baffling, though.
As I fill my radiator it quickly leaks on top where the black plastic area is. Does that require a radiator replacement? 2005 Santa Fe ....
View 3 Replies2002 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 was teaching my kid how to drive in a parking lot and noticed white smoke coming from the front when parked. There seems to be a leak on the top side of the radiator, where the plastic top connects to the aluminum body. I also noticed that radiator fan does not come up at all. Outside temp was around 40F but I would think it should have come on when driving at 5-15 mph in a parking lot for 1+ hours. Temp gauge is on the left side of the middle indicator so technically the engine is not overheated, unless the temp probe is bad. What's the best way to troubleshoot this? I have a 2005 Santa Fe 3.5L GLS FWD.
View 19 RepliesThere were some minor coolant leakage from the upper hose radiator so I have it replaced. Took me 2 hours because the thermostat housing hose neck gunk up with white lime.
Everything works fine but the car still suffering from minor coolant lost. Found some water stain over the bypass hose neck so I get it replaced too. Took me another 2 hours to get it fix because of the white gunk buildup. Secured everything including the hose and the clamps. Minor water stain still can be found at the bypass hose neck.
Replacing the radiator hose? Does it takes few days for the new radiator hose to fit 100%?
So i cant figure out how to remove the radiator side of the upper radiator hose. I pulled out the pin but i cant remove the hose.
Do I just pull it straight out? Or do I twist and pull? I dont want to break the connection.
