    I have the same issue (leaks coolant) from around the retaining nut. It appears that the rubber fitting from inside the plastic tank that stops coolant from leaking is gone Is there a replacement part?

It sounds like you might have a crack in the plastic tank of the radiator. If the line was leaking, I would think you'd see some oil leaking. Any anti-freeze leaking? When the truck is cooled down, I'd check the anti-freeze and oil level.

How to replace the trans cooler line connector in the radiator with clip 2000 s-10 zr-2


The tanks are plastic and if the hose fitting broke out then the fix is a new radiator. As in radiator coolers are prone to failure before you invest in a new radiator , consider buying an air to air oil cooler to cool the transmission oil . The oil will run at ambient temp and not at 95 degrees c or hotter and the radiator is not having the load of trying to cool really hot oil. Talk with an auto transmission shop to get some details and I think that you will find the oil cooler cheaper than a new radiator.

We need to know if the radiator has an enigine oil cooler in it so we know which one to buy


if you get under the car on the driver side were the oil filter is and look were the filter screw onto the motor,if you see 2 large lines coming from the plate that the filter screws onto going to the front of the motor and attach to the lower rad then you have an engine oil cooler in the radiator.there will be lines that come from the transmission to the radiator that are considerably smaller.

How do you replace the radiator in a 1997 Ford Escort?


Check this procedure to REMOVAL & INSTALLATION
(1.8L and 1.9L Engines)

CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Disconnect the negative battery cable.
  2. Place fender covers on the aprons.
  3. Raise and safely support the vehicle. Drain the cooling system.
  4. Remove the right and left-hand front splash shields.
  5. Disconnect the lower radiator hose from the radiator.
  6. If equipped with an automatic transaxle, disconnect the lower oil cooler line from the radiator. Remove the oil cooler line brackets from the bottom of the radiator.
  7. Lower the vehicle.
  8. If equipped with an automatic transaxle and air conditioning, remove the seal located between the radiator and the fan shroud.
  9. If equipped with an automatic transaxle, remove the upper oil cooler line from the radiator.
  10. If equipped with the 1.8L engine, remove the resonance duct from the radiator mounts.
  11. Unplug the cooling fan motor electrical connector and the cooling fan thermoswitch electrical connector.
  12. If necessary, remove the cooling fan thermoswitch for clearance.
  13. Remove the three fan shroud attaching bolts and remove the shroud assembly by pulling it straight up.
  14. On some 1.9L engines equipped with A/C, remove the upper radiator air deflector from the radiator and set it aside.
  15. Remove the upper radiator hose and the two upper radiator mounts.
  16. If equipped, remove the fluid cooler tube bracket bolts and coolant overflow hose from the radiator.
  17. Remove the radiator from the engine compartment by lifting it straight up.


2.0L Engine
(1997 MODELS)
  1. Remove the fan motor, blade and shroud assembly.
  2. Raise the car and support it with safety stands.

Oil fluid leak on left side of car-2000 buick lasabre


If its on the drivers side of the car close to the front check the transmission oil cooler lines. Especially if the fluid is redish in color. You will see them if you look up under the vehicle on the drivers side. There will be to black hoses running between the transmission and the radiator. If they are wet/dripping you found the leak.

How do you change the radiator on a 1996 Buick Skylark?


GM Grand Am/Achieva/Calais/Skylark/Somerset 1985-98 Radiator - REMOVAL & INSTALLATION
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
A cross-flow radiator is used on most models. The radiators used on automatic transaxle models are equipped with oil coolers with inlet and outlet fittings for transmission fluid circulation. An aluminum-plastic radiator can be identified by the black plastic side tanks and aluminum radiator.
  1. Disconnect the negative battery cable.
  2. Drain and recycle the engine coolant.
  3. If necessary for access to the radiator, remove the air intake duct assembly or air cleaner assembly.
  4. On automatic transaxles, disconnect and plug the upper oil cooler line.
  5. Disconnect the engine strut brace at the radiator, loosen the engine side bolt and swing aside, if equipped.
  6. Matchmark and remove the hood latch from the radiator support.
  7. Detach the upper hose and coolant reserve tank hose from the radiator.
  8. Disconnect the forward light harness and fan wiring. Remove the electric cooling fan. On some models this may not be able to be removed unless the front end of the vehicle is raised and supported.
  9. Raise and safely support the vehicle.
  10. Remove the engine cooling fan if not yet done.
  11. If equipped, remove the splash panel below the radiator outlet hose. Detach the lower hose from the radiator.
  12. If equipped, disconnect and plug the lower oil cooler line.
  13. Carefully lower the vehicle.
  14. If equipped with air conditioning, remove the radiator to condenser bolts. Unbolt the refrigerant line clamp. Do not disconnect the lines.
  15. Remove the mounting bolts and clamp, then the shroud (if equipped) and carefully lift the radiator out of the engine compartment.
To install:
  1. Lower the radiator into position.
  2. Install the mounting clamps and bolts, including those associated with air conditioning parts.
  3. Raise and safely support the vehicle.
  4. If equipped, attach the automatic transaxle cooler lines.
  5. Connect the lower hose(s) and attach the splash shield if equipped.
If the engine cooling fan was removed while the vehicle was in the air, install the assembly and attach all electrical wiring.
  1. Carefully lower the vehicle.
  2. If not already done, install the electric cooling fan, then attach the electrical connector(s).
  3. Connect the upper hose and coolant reserve tank hose.
  4. Install the hood latch and strut brace.
  5. Fill the system with coolant.
  6. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their correct levels, then check the automatic transaxle fluid level.
  7. Turn the engine OFF , then once the vehicle has cooled, recheck the coolant level.

  2. Drain the engine coolant into a suitable container.
  3. If necessary for access, remove the air cleaner, mounting stud and duct.
  4. Remove the upper fan mounting bolts.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. To avoid being burned, do NOT remove the thermostat housing cap while the engine is at normal operating temperature. The cooling system will release scalding fluid and steam under pressure if the cap is removed while the engine is still hot.


  1. Remove the cooling fans, as outlined later in this section.
  2. Disconnect the coolant reservoir hose from the radiator neck and the radiator hoses from the radiator.

GMC Yukon has a leak (expelling steam) from the connection to the radiator on left side. Lower connection. Metal hose into a screw fitting. Leaking out the side of the connection. Can this be fixed...


Steam? are you talking about the oil cooler lines? thats the only metal lines I can think of on the left side of the radiator, but those would leak oil. if so there is a o-ring in the fitting that can be replaced. I'm just guessing thats what you are talikng about.
