Re: automatic cooling lines
The only way i will find or sujest that is by unplugin both lines then atach a rober hose to the end of each line, the have some one old one empty plastic soda can on each line end, and cranck the car for a little be, then suply line will push oil while the return won't, and i will apreciate the ranking to me thanx again

You didn't get anything cross-threaded, hopefully? I don't know year--make--model--engine size of vehicle?
Usually when I mount a new radiator, I set the radiator in place, then hook up the tranny lines, first, before the radiator mounts, incase I need to move the radiator a little, to get the threads on the tranny lines to match up with fitting threads on the radiator. I usually tighten the tranny lines last.
Take the leaking line loose, check to see if threads look ok? You may have to take radiator mount loose, so you can move the radiator a little to get threads to match up properly. I haven't used thread tape on plastic lines, I guess you could try it, if else fails?
Actually, it does not matter if you are starting over on the lines. All you need to know is that the fluid flows into the radiator, cools down, and goes back into the transmission. In a later model with a cross-flow radiator, I would say the flow is from the trans and into the top fitting on the radiator tank, and the return is on the bottom. As long as they are tight fittings, you're good to go. They are NOT high pressure, so circle clamps and rubber hoses, about 3/8" diameter links the steel lines where they may be new-to-the- old lines. Since it is a 1968, the chances of original lines may be out unless you are restoring whatever model.My fav was the Challenger. On a Hope this helps.
Those are the transmission fluid cooler lines-one is the pressure line, other is the return line-back into the transmission. Often the cooling reservoir is built into the radiator. Apparently yours has a separate cooler in front of the radiator. It would be that and not the a/c grill.
Automatic transmissions generate a lot of heat. Without a way to cool the transmission fluid, the fluid could get burned-it will look blackened, and is very bad for transmissions. Check your transmission fluid and add if necessary. Stop the leak-it may just be a loose fitting, or a broken line or hose.
if their metal, the could be coming from transmission fluid lines, are they going into radiator ? one @ top & one @ bottom of rad . their cooling lines from trans, supply / return . if rubber lines, they go to a transmission cooler , looks like a small radiator, rectangular , supply / return. power steering has no cooling . these lines don't come from engine, power steering has power steering fluid NOT TO BE MISTAKEN FOR TRANSMISSION FLUID, TOTALLY DIFFERANT !!!!!!
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.
That is a VERY easy radiator. Loosen radiator drain plug and drain coolant from radiator. Disconnect cooling fan connectorsRemove upper and lower radiator hoses after marking them to ease installation. For vehicles equipped with automatic transaxles, disconnect transmission cooler lines at transaxle. Remove air conditioner condenser fixing bolts and radiator bracket fixing nuts. Remove the radiator, radiator cooling fan, air conditioning cooling fan and transmission cooler lines from the vehicle as an assembly. Transfer all necessary parts (fan assemblies, cooler lines, clips, speed nuts, fittings, etc.) to the new radiator.
A Transmission Coolant Line is 2 Lines running from your Transmission to the Radiator 1 line is where transmission fluid goes into the radiator and the #2 line is where it returns to the Transmission, A Automatic transmissions Fluid can Run 400 Degrees or More,The Lines are to Help keep the temperture of the Fluid in your Transmission at a temperture that does'nt exceed the specifications of your transmission operating temperture. Prevent Over Heating and that would result in a Excessive Tep that would cause damage to the Internal Componets and your Front and Rear Seals. NOTE: Some Vehicles Trucks that Tow a Heavy Trailer or something else have a ADD on or some come from the factory with a Truck or SUIV that has a TOW Package on it, if this has this option the Transmission Lines will not go through the Transmission they will go to the Optional Transmission cooler ,thats normally located in front of your Radiator for much better cooling ,it actually works like a Radiator it has Fins and tubes with a Inlet tube and a Outlet tube. This is a Much more effficent cooling Component for your Transmission. Hope i have answered your question. And given you the Help you needed. Thank You.
The cooling system is pretty much self explanatory hoses go from and to the most obvious places...(you wouldn't try to stretch the lower hose all the way across to the upper hose connection). The trans cooler in the radiator can actually be connected either way. It is non-directional, being a simple coil inside the radiator tank. If you want to install an external trans cooler, that's a bit different...it needs to go on the outflow side of the radiator so it can further cool what the radiator has already cooled down. An easy way to find out which side is the return line, simply take one fitting off the radiator, remove the coil wire so engine dosen't start and "bump" the engine over till trans fluid comes out. if out of radiator nipple you are on the correct side, out of hose, install on other side. Leaking lines can be partially replaced using brass compression fittings made for this. Only use them on straight clean runs, not on heavy rust or bends.
