2003 Santa Fe Transmission cooler line leak

Hey everyone, 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 (I'm too new yet to post links, sorry) as item number 5, part number 2547126011. Am I correct in assuming that I'm going to have to remove the entire radiator toget to this thing to replace it? It appears to be fixed in place, but I can't see any hardware to remove it. Any advice would be more than welcome. Thanks in advance!

You shouldn't have to remove the radiator(although I've never done it before). Just looking at it, I think if you remove the bumper and the skid plate on the bottom, I think you could get to both bolts on it. If you haven't removed the bumper before, just take out both headlights to get to the two hidden bolts to remove the bumper. All the other bolts and fasteners are fairly easy to get to. Takes about half an hour. Take a look at the pictures on this link, just below the package of what you are buying:

Thanks, that is some good news. I had taken the bumper off in anticipation of swapping the oil cooler out, so not only am I familiar with that, but all of those nasty, rusty screws and bolts are now cooperating. I was just looking from the ground, I'll have to put it up and see if I can see the attachment points with a little better angle. I can't seem to find any reference anywhere on specifically where this thing bolts to, which seems odd, but my Google-fu may not be so terribly strong today :smile:

Call dealer to run VIN for cooler tube recall.. still some out there that aint seen dealer aisle in yrs..

Warranty give 66 minute to do the replacement.. bump cover off, on rack is easier, bolt on flange for tube assembly to radiator tank.. I unbolt upper core supprt, and center brace, then lift driver side of radiator/condenser to pass old tube out, and slip new tube in,,, just dont put hole in condenser or radiator....

DON'T ASK HOW I KNOW ABOUT THAT TRICK......

Search for Hyundai document 02-01-011 for instructions on doing the job

Thanks again, guys. Finally got the part in, as the only active recall on my vehicle is for coil springs. In Hyundai document 02-01-011 it indicates that hose clamps come with the part, but there aren't any in the bag, I'm assuming there's no way to re-use those dreadful things that are on there now, right? I'll grab a bag of worm-drive type clamps before I dig in to this thing this AM.

Tube kit called in recall is 25470-26A00... tubes and clamps (we have 2 of them on shelf)

Clamps is availabe as service part.. I'd shy away from "worm clamps"..


The bag I have has the tube assembly in it, and also includes a bag of (4) 25331-38215 clamps

Sound like they sold you the non-recall part....
