PnP for my 89S4. Second summer with it and my temps are back to normal.
Looks great in my car as well. Make sure your rubber mounts are not solid due to age if you're going the alum type.

 

I have have a 928 MS radiator for over three years, also replaced the rubber mounting pads.
No drain is a plus, nothing to break off!
It never runs temp needle above half way. The Behr ran at the second red line. It is thicker, but fits fine.
Uses the standard temp sender and overflow nipple, recommend a new nipple as they are cheap and old plastic will break.

There has been much discussion about our radiators, and we carry a 2-year warranty on them. They have been in the field for 5+ years now. Use the search feature in Rennlist of you like...

 

Just ordered one yesterday. Now does anyone need a good, non leaking Behr with no coolers?

 

I didn't install mine the PO did but absolutely no cooling issues. Stays below halfway always. Black car in Texas and all....

 

Do a search on all aluminium radiators and leaks on this forum and you'll get your answer. Many leak onlynafter a short use, including the one I installed.

 

I disagree with the term "many" unless you are talking about all aluminum rads from all manufacturers over the years. There have been some that were not as well-built as ours.

I can only control (and speak for) our own. We have not had "many" fail and those that have, have been replaced without charge to the customer. We provide a 2-year warranty.

 

I just put some JB Weld over a small weep on one of my tank joints. Hope it lasts until I can pop for a new radiator. Pop wow that's funny.
