They are a type of quick connect fitting. There is a special tool just for these types of fittings. If you remove the plastic cover that goes over the fitting you will see a metal clip in a groove. You can use a small pick to carefully remove the clip (they go flyin and get lost easily but they are available from your local GM dealer or parts store). Once the clip is removed you will be able to pull the line out of the radiator/transmission fitting.

Reinstall the clip after you remove the line. The new line will slide in and click into place.

    I am trying to reinstall one of these transmission lines into a Pontiac Aztek '01 radiator. The clip and the trans line went in smoothly but I can't place the black plastic protection cap/cover back on top of the metal clip like it was before. How do I get back to cover it? There is not enough room, the metal clip does not allow the plastic cover to slide on top of it. Do I have to first place the metal clip, then the plastic cover on top and THEN connect the transmission line?

Is it posible for the transmission atf to leak inside the radiator. because i dettect water inside the transmission and oil in the radiatorssion smission


Yes.
most cars have a transmission cooler that runs through the radiator. Most often the coolant goes from the cooling system to the transmission and then quickly ruins the transmission..
you should get this fixed asap, hopefully you can avoid a transmission failure. A quick remedy would be to un hook the transmission cooling lines from the radiator then cap the ends on the radiator and then mount a separate transmission cooler.
The big problem is that you will need to flush that transmission as soon as you can. Get the trans oil changed pronto!

Why would there be transmisson fluid leaking out of radiator?


Radiators on automatics have a separate reservoir for transm. fluid cooling purposes. Didn't you remove the transm. fluid cooling lines from the radiator-a feed line to the radiator and a return line from radiator to the transmission? They are small steel lines that connect on the end of the radiator.

    When i crank up my explorer it is pouring transmission fluid stop at a red light an it leaked out a quart of fluid


    You won't go far this way. Its cheaper to tow it than replace a transmission. There are a few fluid lines to check at the transmission. Several servos and the speedometer sender are in the case.
    They have gaskets and the plastic may crack. The Transmission pan can leak. The fill tube can separate from the transmission.

    If the leak is coming from the inspection cover next to the engine, it can be a front seal, and if the leak is coming from where the drive-shaft slides into the transmission housing, that's a tail-shaft seal.

    The fluid lines run to the front of the SUV to the Radiator where there are cooling lines going into the bottom of the Radiator. It can leak from a Radiator tank hole because there are 2 separate tanks in the Radiator. Then all you do is replace the Radiator. On some models there may be a separate Air cooled Auxiliary radiator, not to be confused with a power steering cooler.

    The fluid lines will rust and need replacing. If you are trying to make a line, there are different flares for the tubing ends. Bring in your bad part to match it up.

    I hope my solution is helpful to you. You need to be under the SUV to see anything. Even a quick change lube bay would make it possible to find a leak.

    Radiator Removal
    1. Drain the cooling system by removing the radiator cap and attaching a 9.5mm (3/8-inch) inside diameter hose to the draincock nipple, located at the lower rear corner of the radiator tank. Then, open the draincock and allow the coolant to flow through the hose into a suitable container.
    1. Remove the rubber overflow tube from the radiator and store it out of the way.
    1. Remove the shroud's or finger guard's two upper attaching screws. Lift the shroud out of the lower retaining clips and drape it on the fan.
    1. Loosen upper and lower hose clamps at the radiator and remove hoses from the radiator connectors.
    1. For vehicles with automatic transmissions:
      1. Disconnect the two transmission cooling lines from the oil cooler fittings on the radiator. Intermediate flare fittings as shown remain as originally installed.
      1. Disconnect the transmission cooler tube support bracket from the bottom flange of the radiator by removing the screw.

    1. Remove the two radiator upper attaching screws.
    1. Tilt the radiator back (rearward) approximately 25mm (one inch) and lift directly upward, clear of the radiator support and the cooling fan.
    1. If either hose is to be replaced, loosen clamp at the engine end and slip the hose off the connections with a twisting motion.
    1. Lift the shroud off the fan and remove from the vehicle.
    1. Remove the radiator lower support rubber insulators.

    9. Remove the four (4) fan shroud to core support mounting screws.
    10. Remove the electric fan (if equipped) and shroud assembly from the vehicle
    11. Remove radiator upper crossmember.
    12. If equipped with air conditioning, separate radiator from condenser by removing condenser-to-radiator mounting brackets.
    13. Disconnect upper and lower radiator hoses.
    14. If equipped, disconnect and plug automatic transmission fluid cooler lines. Quick Connect Fitting Release Tool 6935 may be needed. If equipped with remote transmission cooler, remove line to cooler from bracket at bottom of radiator

    To install:
    1. The radiator is supplied with two alignment dowels. They are located on the bottom tank and fit into rubber grommets in the radiator lower crossmember.
    2. Lower radiator into engine compartment. Position alignment dowels into rubber grommets in radiator lower crossmember.
    3. If equipped with air conditioning, attach condenser to radiator with mounting brackets
    4. Install radiator upper crossmember and four mounting bolts.
    5. Install radiator upper crossmember-to-isolator nuts. Tighten nuts to 86 inch lbs. (10 Nm) torque. If isolator-to-radiator nuts had been removed, tighten them to 47 inch lbs. (5 Nm).
    6. Connect radiator upper and lower hoses.
    7. If equipped, connect automatic transmission fluid cooler lines. If equipped with remote cooler, attach cooler line to bracket at bottom of radiator.
    8. Install electric fan (if equipped) and shroud assembly. Insert alignment tabs at bottom of fan shroud into slots in bracket at bottom of radiator. Tighten mounting bolts to 31 inch lbs. (3 Nm).
    9. Connect electric cooling fan electrical connector.
    10. Install power steering reservoir to fan shroud.
    11. Install grill.
    12. Connect battery negative cable.
    13. Fill cooling system with correct coolant.
    14. Install pressure cap.
    15. Check and adjust automatic transmission fluid level (if equipped)
    16. Start engine and visually check for leaks.

    For more details I suggest review the Service Repair Manual:
    - Section-07-Cooling-System-Ewj7 (page 33 and next)
    - Section-07a-Cooling-System-Ewj7a

    I really hope helped with this (remember rated and comment this help) Good luck.
