2001 Buick Lesabre Radiator transmission line leak
 

Hello Everyone ,
Today I saw a leak from the upper connection with the radiator , from the bolt .
what i need to replace ? the bolt ? or there is any seal ?

Thanks

Can you take a picture? Reason I ask is, I can't think of any bolts in the radiator that would leak.

Do you have the quick disconnects/j clips like in this link?

GM, Transmission, Oil Cooler Line Quick Connectors & Retainer Clips On FMSI

I think I do have like this .
I'll take a picture tomorrow and i post it

Is that where it is leaking? That's where mine was.

anyone know what the part name ? number ?

If you clean the gunk off is there a metal clip? That looks like the transmission cooler line quick disconnect fitting.

I would Brake Klean that whole area first, and then recheck....

i would agree, you cant tell if its years of grime or something current unless you clean it then look for leaks. as far as the connector i believe that type pulls out. it is a quick connect type the nut part seals against the rad and the ring holds the tube in

Nope, I see what we called in the Army a, Class 1 leak. In the last photo, you see a drip forming. From the looks of the drop, it looks thin and clear. Much like coolant.

So it's not transmission fluid :confused:?
how can I fix it ?
someone have a guide how to replace it ?

Thanks

Knowing my luck, it could be trans fluid. But, it doesn't matter either way. Whatever is leaking from that location, is not repairable. Where that line goes into, is what's called a quick disconnect fitting. If you slide the plastic clip back down the line, you will see a little C-spring clip inside the housing. Once that is out, the line will pop right out. Now, that quick disconnect fitting is removable from the radiator. It could be as simple as replacing that quick disconnect fitting. But this kind of requires special tools to accomplish. Unless you are savvy in a tool box, you could figure it out.

I suggest taking it to a reputable shop(NOT A QUICK OIL CHANGE SHOP!!) and have them take a quick peek at it.

Mike, I just don't see the "obvious" leak in the picture.....that could be something that was spilled....just suggested a good cleaning to get an idea of if it is leaking, what is leaking, and how bad it is leaking....

Update!
I replaced the connector and the leak stop . I hope so ...

Thanks !

That is great. Glad to hear that it was only the fitting.
