Opel GT US radiator

[opelgtfan69]

Hello,

I would like to replace the radiator (wasserkuhler) but I discovered a small tube under it (see the picture http://postimg.org/image/yrqnqh7ul/). That GT is a US GT-AL.

Is this an oil circuit ? what is that for ? is this linked to the automatic gearbox ?

How can I remove that thing and what do i need to put in after ?

It looks like radiators for GT US are different than the others. Suselbeek for example sells another one more expensive for GT US :

Thanks a lot !!! Bye

Hello Francis,
You're right, it's a radiator for an automatic transmission (gearbox).

You will receive a new here:

Thanks again for your help !! Bye
