Santa FE SM (2001-06) :: 2003 - Heavy Oil Leak
Aug 6, 2015
I have a 2003 Santa Fe with 187,000KM on the clock. The mechanic noted on it's service that there is a heavy oil leak and suggested it might be the valve cover gaskets or the timing cover. I had the valve cover gaskets replaced by a friend, but unfortunately the car is still leaking oil - presumably from the timing cover. The driveway is covered in oil, the car smells while being driven and needs topping up with oil. I have kept the car going for a while like this, but am uncomfortable with it.
The mechanic suggested there is a possibility it could be a water pump causing the leak and the repair on this would be super expensive, but they can't tell until they're inside.

Several weeks ago I made another thread because I was having crankshaft position sensor problems and essentially that was due to a short on the sensors wires which had become exposed. I replaced the sensor and it still did not work until later trying another brand which solved the problem.
I also changed all six spark plugs, wires, and plenum gasket with OEM parts. I was able to get to the back three plugs by following this tutorial with the guidance of a friend who is a mechanic. After getting this done, the car has run way better and smoother.
However, today it has been raining heavily and I needed to run an errand so I went to my car and turned the key but nothing happened. All the dash lights turned on and appeared normal. My radio works, lights work, etc; but I can not get the car to crank at all. I hear the fuel pump turn on and everything else sounds normal, but still no crank. There are no sounds from the starter at all, it is silent when I try to get the car to turn over.
I took a look at the car and the coil pack seems dry, the plug wires are secure, plus we had put di-electric grease on all those connections. The negative terminal on the battery has a solid connection. I even tried jumping the car to see if maybe it was due to the battery, but again nothing happened.
This has only happened once before when it was raining, before I had changed the plugs and wires, but I was able to get it to crank over after about 4 minutes of waiting and contemplating getting a tow. I took a look at all the fuses and they appear to be intact.

I've just (a couple of weeks ago) purchased an 03 Santa Fe. I noticed some trans fluid on my driveway a week later, and not a small amount. I took the lower cover off of the engine, and the leak is coming from the transmission oil cooler area. I had hopes that it would be something fairly straightforward to repair, so I got a replacement oil cooler and some spare hose, just in case it was just a hose. After getting the front bumper off, I found that the bottom of the oil cooler is clean and dry-- not the issue. It looks as though the leak is coming from what they're calling the Trans oil cooler "tube assembly", as illustrated on the Hyundai Parts Department trans cooler page as item number 5, part number 2547126011. Am I correct in assuming that I'm going to have to remove the entire radiator to get to this thing to replace it? It appears to be fixed in place, but I can't see any hardware to remove it.

I've had this problem for a little while now, my 97' F150 V8 4.6L, has been running real loud and heavy. When it starts up it sounds like a race car. It finally shot me a code for P0171 - Bank 1 (passenger side) running too lean. From what I've read, this is most likely a vacuum leak but I don't know too much about it.
A couple of things I've noticed while driving it around:
1. If you are in the engine compartment while its running, you smell the excess gas on the passenger side of the truck.
2. The exhaust also smells really heavy
3. The loud and heavy running is mainly when accelerating, if I maintain a constant speed at for a little while it almost starts to run normal. Cruising down the highway its almost just as quiet as before the issue
4. Engine coolant heats up much more quickly, but doesn't get above operating temperature (read from tuner, never above 200 degrees)
In response to the problem I replaced both the O2 sensors closest to the engine and the PCV and elbow. No change. Have a fuel filter ready to install, but for some reason I don't think that is it either, as it would probably effect both bank 1 and 2.
Like I said I'm not too well versed in the vacuum system but if any of these symptoms stand out I'd love to hear your thoughts.

I have a 2003 Santa Fe 3.5 liter. I have a bad power steering leak and the dealership says I need
pressure hose
return hose
cooler hose
I've tried all the local car part stores and Napa has the pressure hose but for about $180.

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.

My 2001 Santa Fe is having some major issues with rough idling, and there is a fairly significant oil leak. The check engine light is not on. In the past year it has had a new fuel pump, fuel filter, valve gasket covers, spark plugs, spark plug cables, and transmission.

I just purchased a 2006 Santa Fe Limited with the 3.5l for a great deal. It has a huge coolant leak though that needs fixed. It is coming from the top of the motor on the left side by the timing belt. It is really a small flood, when you fill the coolant and turn on the motor it runs across the top of the motor toward the drivers side. There isn't oil in the coolant and it doesn't smoke. I had it dropped off at my mechanic though. Does the motor really need pulled in these to do the head? I heard that there is a overflow channel from the water pump that comes out right about there as well. Could that maybe be it? Any other options if it is the head gasket to reduce the cost any?

I've been told that the 2002 Santa Fe that I drive has a small leak in the head gasket and that this will be a major problem for the A/C compressor in the not-too-distant future. Supposedly the compressor is located below where the leak is and that over time (5-6 months) this can/will cause the compressor to need to be replaced. Does this seem like a credible scenario?

I had the abs come on on dry pavement.. I changed the front ring gears,, Bought 2 new axles with ring gears all new on there.. fixed the issue.. Now i have a oil leak--transmission oil at the driver's side axle.. Is that the seal there in the trans that should be replaced? difficult? Why leak now if it wasn't leaking before..

I have an Oct 2001 2.7 GLS which apart from the odd ABS Tone Wheel and speed sensor issues has been uber reliable and a real pleasure to own (I've had it from new).
We had a problem about a year ago when the wife didn't get the fuel cut-off when filling up and over filled the car resulting in fuel pouring out of the tank vent and down the fuel tank under the car but after a long drive that cleared up and has not happened again. Interestingly we didn't get any engine CEL's or have any codes turn up at all when checked by my mechanic.
Over the past couple of weeks we have noticed a very strong smell of fuel under the car around the fuel tank. I can't see any indication that there is a fuel leak but have noticed when filling up that the smell is very strong and as the car runs the fuel down the smell reduces to almost nothing.
Today I removed the rear seats and the fuel pump access panels to see if there was any seeping around the pump gaskets but couldn't see anything and the top of the tank around the both pumps was a dry as a bone. Using a torch I did however notice that there was a darkening of the fuel tank surface in the centre which I guess is close to the vent valve, part 311990b:
Or maybe is where the fuel vent pipe runs to?

I just joined the forum mainly to care of my dads 2001 Hyundai Santa Fe but also I got a check engine light on my way home from work last night.
From last night I saw that oil was all over the timing belt. Today I inspected it with a Coworker and his OBD II reader.
Error Code was P0455, EVAP - Evaporative Emission Control System Leak Detected (gross leak).
Now the oil leak is stronger since the oil spills is on hood (inside hood). I will make a picture tonight when I get home.
I personal think it's leaking from a tube/ valve on top of the timing belt (picture will show more tonight). Thinking of cleaning the timing belt area, then drive a little around or leave it in idle to spot where the leak is from.
Common issue? I googled around but since P0455 is a common issue (on my 9-2x as well) I couldn't find anything about this I am also limited from my search since I am currently at my work PC incl. strong firewall.
I will see if google let me find a picture...

I have a leak coming from the top of my reservoir from the under the cap for some reason. I bought a new cap and it seem to stop for a day and now it leaking out from under the cap again. What is the reason it would be coming out of there. Am I going to have to replace the reservoir??

2004 XG350 with the Sigma engine, 133,xxx miles.
In the picture I attached, the large silver bolt is leaking. Its a slow leak: yesterday morning I wiped it off, and then we I got home from work there was a bead of power steering fluid, but not enough to drip.
What is the best way to fix this? Is it as simple as tightening it?

Going up my driveway (its kinda steep) after 4 or 5 inches of fresh snow fall- smoke in the engine bay and inside the car. Its a 2003, Santa Fe with the big V6. Driving on level ground it doesn't smoke. I thought it must be the 4WD which I guess only kicks in when needed, driveway hadn't been snow blown yet. Saw a couple dots of red in the snow afterward. Didn't notice it before. But on the way to work tonight (same day) the power steering was not a 100%. The reservoir is down, right on the minimum mark. So now I'm thinking I have a leak and the smoke is from the PS fluid hitting the exhaust. Though why it only smokes in my driveway beats me. It looks as though the exhaust on this engine (big V6) is directly underneath the pump. I think I can verify it tomorrow. Would a PS leak in the vicinity of the pump fall onto the exhaust? Think this is the smoking gun? I can't even see the pump. But the manual says its on the left/rear.

Well, I have the dreaded transfer case leak on my 112000 mile 03 2.7 santa fe. I have just returned from a 12,000 mile trip through Canada, Alaska and then back to Colorado. During that trip I was smelling a burning oil smell and after I came back I traced it to the transfer case. I think it is leaking both from where it mates to the drive train and a one inch seam along the transfer case plate.
It has leaked there for some time(and I had been diligent about filling it up), but this extended trip it has has been more bothersome. I called the local Hyundai shop and they want $1100 and won't guarantee a fix. Is there some product I could use on that one inch seam externally to stop the leak (I know that wouldn't seal the circular seam around the drive shaft)? I kept very accurate gas records and averaged 25.6 MPG for the whole 12k trip running from 55 to 65 MPH.

Got a leak that just developed after a long trip. It's not big, but I am not sure what it could be? I see in front of the rad is a smaller looking rad, and in front of that behind the grill in the bumper is an even smaller radiator-radiator-looking box. I see two small hoses coming out of it, down under the rads but above that metal brace. Does that hold coolant? Or one of the other radiators?

Notice a leak at the bottom of the Line coming out of the reservoir and turning under at the bottom of the radiator... Not sure at this point whether this is the suction return or supply , probably return, from the looks of the spring clamps used.
It appears that some steel line is used to make a 2 ft or so loop under the radiator before it goes back to the rack.... Cooling??
This line app. 3/8 " in diamater is supported by some rubber isolators, and no doubt there is some rust which has formed in there where the line passes through the rubber, small pinhole maybe??

My 2001 Santa Fe had a slow PS leak for over a year which I dealt with just by adding fluid several times a year. Then I let the car sit for a few months while I saved up for input/output sensors. I just replaced those and discovered that the PS leak is noticeably worse.
I searched the forums and found that the most common problem is a clogged reservoir screen, resulting in fluid backup that sprays the engine bay. I don't think that's the problem. The engine bay is dry and both reservoir hoses are dry. The spot where I've found the most wetness is closer to the firewall and much lower than the reservoir but I need identifying it.

I am beginning to get a rusty colored leak at the interface between the transfer case and transaxle on my 2003 Santa Fe 2.7l 4wd. There wasn't any leak less than a week ago. What would make the transaxle and transfer case start leaking at the same time?

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.
