300SDL Radiator - Now It’s MY Turn To Buy One!
 

Just purchased an all aluminum radiator for my SDL. In a brilliant move changing out engine mounts a month ago I managed to break the upper neck. I was already planning on a replacement radiator because the overflow nipple was broken and repaired with a brass barb. Whoever did the work had done a relatively decent job, but I wasn’t going to trust it for too much longer. So I wouldn’t have the SDL taking up garage space I repaired the upper neck and double clamped it. It did not leak in the 3k miles I put on it after the repair. The brass barb started leaking though. I went ahead and bit the bullet. The new radiator will arrive on Thursday of this week. It’s a shame that the original style radiator is NLA, but I don’t anticipate having to replace this new radiator for a long time...as long as no outside culprit causes damage. Wish me luck!

Good luck! My roommate has a 1991 350SDL and the center of the radiator has a fairly large area of JB Weld or something over the core. It's holding, but I think I'd rather have an all-aluminum radiator than an aluminum one with plastic tanks. One day he may end up getting an all-aluminum radiator, though we may end up painting it black.

Last I heard there was some Chinese one available for cheap and Wizard Cooling in NY.

Yay!
 

It’s here! It’s beautiful!!!

I was gonna say, you can have my upper radiator neck, but you already have another radiator.

Where did you buy it?

I think...
 

Liland. It was an Ebay purchase.

Remember: Photos, or it didn't happen ;)

Well...
 

I’d love to, but I just updated my iPhone and it has disabled my camera!

Pics!
 

Here it is!

That is exactly like the one I purchased for my SDL a couple years ago. It worked great for the years I had the car, finally sold it to a guy in Europe.

Boggles the mind that these aren't available for the W124 diesels.
About to have to buy another radiator and would love a aluminum one!

Almost afraid to talk about this (knocking on wood) I have a brand new OEM radiator in box and have always felt as long as I have it.......will never need one.

What is the difference between a 126 and 124 radiator in each chassis that uses the same engine? (just curious, have never thought about what might or might not interchange).

Mounting configuration. 126 has vertical flow with the transmission cooler in the bottom tank. 124 is crossflow with the transmission cooler in the side tank. The hose layout is slightly different too, the 124 has the coolant expansion bottle hooked up to the radiator, the 126 has the hose for that purpose splitting off from the lower radiator hose.

Subtle differences, but enough to cause problems for installation without custom fabrication.
