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
