Leaking coolant from plastic tank

[Boldhead]

Hi Guys, hope someone can help me!

I have a 1997 4.0 V6 SOHC Explorer (bought back in 2008).
A couple of days ago I noticed a small coolant leak in the area of the lower connection of the transmission oil cooler.

After searching this forum I found a thread about tranny fluid leak in the same area (with TSB about new O-rings), but in my case it's a coolant leak. I have no idea what's inside of this plastic part of the radiator, so I can not tell whether the coolant could come from the oil cooler connection or from the seam between the central and the plastic part of the radiator????

Any thoughts?

They usually start leaking at the seam between the plastic tank and the metal core.

A lot of our members have went with an aluminum radiator as a replacement. This one is three core: http://www.ebay.com/itm/3-ROW-FULL-...ash=item2c7a174cf5:g:kqMAAOSwDNdV5M6q&vxp=mtr

Thanks Rick,
If I have to replace the radiator, yes I would like to buy a full alu one.
Hopefully I could find one here in Europe, because shipping of the one you mentioned costs more than the radiator itself.
You write "usually", do you think it's posssible they start leaking coolant from within the plastic part around the connection for the tranny cooling? Again, I don't have any idea how the internals of the plastic part look like.....
