Santa FE SM (2001-06) :: 2003 - Transmission Cooler Line Leak
Nov 11, 2016
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.

Had a small leak on show up in my transmission cooler line at the radiator connection. After replacing the o-ring, which was pinched, I had lost some fluid up to about 3-4 oz. I had stopped by the local VW dealer and picked up a liter of ATF fluid and noticed the colors of the fluid differed from what drained out from the cooler line. Fluid that drained out was a cloudy darker green/grey and the new ATF fluid had a clear yellowish tint. Is this vehicle equipped with a closed loop cooling system or does it use the actual ATF fluid as the cooling medium?

I have a 2008 Ford F250 V-10 Superduty and recently I had a transmission cooler line start to leak. I ordered replacement lines and the tool for the quick disconnect. The line that's leaking is from the radiator to the quick disconnect. I was able to replace the one line, however the second line (problem area) has been a nightmare. The line cracked right at the quick disconnect fitting.
The hard line is tight in the fitting and corroded. broke the tool trying to remove from disconnect. The line is flush with the quick disconnect. How to get that out of the fitting? or another method of fix? Its a hard 1/2 line going into connect crimped to rubber line going to transmission.

Transmission oil cooler line, lower one, is leaking. I think to use pvf, black ones, brake line instead of new transmission oil cooler line. I did replaced upper one with new transmission oil cooler line before a few years and it is rusty already as those line are only zinc plated as opposed to plastified brake lines.

As explained in the photo annotations, I can't figure out how to remove this line from the radiator so I can remove the radiator for cleaning.

I bought a 2003 F250 7.3 Powerstroke from a buddy of mine with 99,500 miles. It is a former Michigan truck and has some significant rust issues. Oil pan and drivers door will need to be replaced in the not too distant future. And probably bed rails later too.
In any case, I noticed a puddle of tranny fluid on the driveway when I got home today. The passenger side line at the fitting into the bottom of the radiator has corroded through. The fitting into the radiator is pretty rusty, and the line fitting is darn near destroyed. The line itself actually has a hole in it.
I see the same part numbers on different sites with different descriptions. Driver side here, passenger side there, inlet here, outlet there. For the same number.
As near as I can tell, Dorman number 624-059 is the outlet line from the tranny to the passenger side radiator fitting, and should be the part I need. Correct? Dorman 624-058 seems to be the line from the OTA auxiliary cooler and back to the tranny. What I cant find is the line from driver side radiator to the OTA cooler. That fitting is corroded bad too, and I may as well do both of them.

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??

What is the location of the Transmission Cooler Line? Is it by the radiator?

The oil cooler mounted above the oil filter on my 2002 Explorer 4.0L V6 has a major coolant leak on one of the external line/hose bib elbow. I've googled Explorer oil coolers and I've searched this forum with no luck. Can you bypass it without any problems mechanically or electronically (throwing error codes)? I have already purchased a new cooler and the lower oil cooler line. I'm just wondering if I should return the parts and bypass it. If I go through the replacement, I noticed the cooler is mounted by a pass through threaded tube with a hex head molded into it for fastening/loosening purposes. What size hex head socket it is?

I have a 2007 Ford Explorer Sport Trac v-6. This truck has been the bane of my existence since I bought it back in September, but I finally fixed all of the issues I was having and it's been great. But, today I discovered that during the most recent work, the transmission cooler line ( Ford part # 7L2Z7890A) was left unsecured against the tensioner pulley. Needless to say, today a hole appeared that gushed tranny fluid everywhere.
I have two questions please- First, need to find the hose diameter so I can do a quick fix insert long enough to drive 1 hr. home? Second, I read online that there is a fluid fill point on the passenger side of the transmission case, is this correct and do I need to be aware of anything else to add enough fluid to safely drive the 80 miles home?
I haven't lost enough fluid that my driving is becoming sluggish and hesitant, but I can tell it is very low.

I have a leak in my inter-cooler system. I have replaced all the hoses. Is there a reason I should not pressure test the system with 20psi? 2001 F350 7.3 turbo....

The transmission line running under the radiator has started to leak. I took a piece of rubber trans. hose and buy passed the cooler. How much does the cooler support the trans. temperature. I don't tow with the truck. And for the most part drive it around 14 to 20 miles one way to work. Is this something I need to replace now or after the temperature hits the 80s.

I've a 2000 Chevy Monte Carol, 110K miles, 3.4L. How to remove the transmission cooler line that connects to the radiator. Can't seem to break the bolt loose that screws into the radiator. Not sure whether this is a quick connect fitting or not! it definitely doesn't seems like it. Also having problems removing the fan shroud. It doesn't seem to want to come out. Should this be remove prior to removing the cooler line?

So my 2000 f350 is leaking transmission fluid from the cooler line. It goes to the rear of the transmission, but where does it go to from there?

Have a 2007 V10 and I want to put in a Magnafine tranny filter. Instructions say to plumb it in to the return line. Which one is this, top or bottom?

I have 2002 F150 5.4L gas 4X4 Lariat FX4. Last winter when it got to -30C here in Manitoba one of the lines near the power steering cooler began to leak. I had just bought this truck and upon investigating found that the original line had been replaced and reattached with hose clamps. I had this "farmer fix" redone but then this winter when it hit -30C it blew apart. Obviously something happened to this line before I got it, so I am curious if there is an issue with these power steering cooler lines when it gets really cold. Should I just get factory lines installed and hope for the best?

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..

So changing the oil in my truck the other day, I noticed the exhaust clamp at the union between my down pipe and first section of my exhaust has been rubbing the trans cooler line and there's a Nick in the granny pan. Lookin at the rubber grommet on the hanger, its stretched tight and looks like the exhaust has shifted over. What could have done this or possible fixes?right by now it's got a gob of high temp silicone acting as a stand off. Don't wanna put the new line in until I have the situation remedied.

I have a 2001 E350 van with the 4R100 Transmission. It had a severe and sudden leak develop in the trans cooler. The driver noted trouble getting the vehicle into gear, into reverse, but ultimately drove it about 25 miles until it stopped unable to go up a hill. Once stopped, the leaking fluid was obvious from smoke & fluid over the back of the vehicle.
It was towed to a local shop (not a transmission shop). They put 9 quarts of fluid in and started the engine hoping to see the transmission functional but only leaking from the cooler. Instead they found it not operational and no fluid coming from the leak. They assume the pump is ruined to the point of not pumping fluid at all.
Is it likely that the front pump is the only damage? Can I pull the unit swap the pump & put it back in service? What else (if more damage is likely) would a transmission repair shop find? What about a used transmission?

Can I change these out to hydraulic hoses with clamps that are rated for the fluid. Mine are rusted and starting to leak.
