    Need Help with Leak on my E24

    I just bought an 89 BMW 635 CSI.... I love the car, that's why even if I am not knowledgeable mechanically, I still bought this car. I am planning to learn from this car. My problem right now is I spotted a leak near the radiator (right side) and it seem coming from a tube connection. I have taken pics, but since I'm new here. I am not allowed to post pics. Can somebody help me? I can send the pics by email or by smart phone. Thanks in advance!!!

    leak

    Ruddy,

    Welcome.

    Probably the plastic side of the radiator, if its a connection. Add some white plumbers tape to the threads.
    Plastic is brittle and you might break it trying to remove.

    How many miles on your car.

    BMW parts look up link.

    May I have your email address, Taylor? Thanks.

    I don't think it's coming from the radiator though. It looks to me that it's oil and the tubing is just passing by the side of the radiator. My E24 has only 86,400 miles.

    Here are the pics from our new contributor.
    Clearly the leaking fluid is ATF . It's a bit difficult to get locational context but I believe that the lines shown are those from the trannie to the ATF cooler on the passenger side of the rad. I have a standard and am ignorant of AT doodaderies so I'm kind of guessing at that.... please chime in !

    I second your evaluation, Taylor. It's either a loose fitting at the radiator or a crack in the line/rad.

    I hope for a lose fitting (try to fasten using Feel-und-tight technique). Behr radiator has metal fittings that are pretty sturdy

    My vote goes toward seeping hose. There is not much else to do but replace it. You have a feed hose and a return hose. Both are about 2 feet each and pressed into a fitted hard line that runs along the nose, and then the driver's side all the way to the tranny. One connects directly, while the other connects to another short soft hose. I forget which one is which, but they're sold separately (3 pieces, including the shorty at the tranny).

    You can replace them yourself. However, the car is best on a lift, or at least high on jacks so you can properly fish through the new hard lines.

    The other option is to have specialty shop press on new soft hoses.

    An Indy shop will probably ask about $300 if you wanna have it done.

    And, welcome to the forum! Lots of us post pics on photobucket and post an image tag here.

    Thanks guys for your input. I will update you on whatever will come out of my Shark's situation. I just hope it will be easy on my pocket. Thanks also for welcoming me!!!

    Hi "bimas"! You are right! I went to a couple of transmission mechanic today, and they both suggested replacing those metal hose. Would you know where I can buy them? The labor charge is $160 though. The other guy told me if I can't find the part. He can bring it to a machine shop for replacement, but he don't know how much the shop will ask to do it. Labor charge for that is the same. What do you guys think?

    Welcome!

    Ok, you said you wanted to learn, so to do this, you first need to go to one of the parts catalogs** and look up the parts and their numbers to see what you are dealing with. You can now see the hoses and lines and how they generally run. The first thing is to wipe them down and see exactly where the leak is coming from. You may just need to tighten the top fitting? In your last photo, it shows the bottom radiator fitting and hose (Ref #3) and the hose looks pretty weather checked, so it might be a good idea buy replacements or have the lines rebuilt at a local hose shop.


    Ref# 13 Bolts into the transmission and the fittings at the other end of the lines attach to the Transmission Oil Cooler fittings which is incorporated into the radiator.
    _________

    Normally you would next check Your Bentley** and the Factory Workshop Manual** for help in the task but there is very little on the transmission oil cooler lines except where they connect to the transmission.

    As to the parts**, the online dealer, GetBMWParts wants $57 (+shipping) for Ref #1 and $60 (+shipping) for Ref #3, not bad. It would probably cost that much to have them rebuilt. Neither AutoHaus nor PelicanParts seem to have an aftermarket part so it seems to be a "Dealer Only" part. If you can get a local Dealer to get close to matching the price (and some will), you can save the shipping.


    ** This stuff is all found on this "Goodies Page". It has links to Online (or PDF Downloads) of the Factory Workshop Manuals, Wiring Diagrams (ETM's), Parts Manuals, Online Suppliers, etc.:

    I use Tomkinson BMW ( no affil) for dealer only parts, nice guys and I have cross-referenced to other dealer sites suggested and they are at worst, the same price and most times better. Your parts were 53 and 56 bucks respectively with 10 bucks S and H.

    I just found this helpful and wanted to say thanks, as I also found the same leak on my 89.
