Yes it is replaceable.
Hoping that you can pull it out of the old radiator.

Regards,
aam.

Found this leak today. I didnt touch it just yet Im waiting for my engine to cool down. Is this something that is replaceable or part of the radiator?
One thing to consider: The radiator tank and necks are made of the same type and age of plastic, and have been exposed to the same coolant/environment. How long before the tank or neck goes?
I suggest you do what I and others have... Replace with all aluminum rad.
Good Luck.

Aluminum radiator, half the dealer price and more coolant.
Where do you get an all Aluminum radiator for 1/2 dealer price???

My original radiator, 19 years old, is still performing fine… but I was thinking just in case…

…Why would I want to pay more for an aftermarket while genuine MB radiator lasted this long… without any problems.

Dud to remove the elbow you need to take off the top hose .Find a ring spaner to fit over the elbow from inside the radiator it must be small enough to close in the tangs that stick out that hold it inside .Be careful removing it so you dont damage it .Then find a good O ring fit it to the base of the elbow and pop it back in .

I paid $274 for mine on eBay same quality AutohausAZ sells. The hose necks crack on the plastic radiators plus the aluminum one holds more coolant. Liland 1314AA
Good to know. Yeah, these plastic hose necks always make me nervous when working with old radiator. That said, I only ever managed to break off one of them and that was on a radiator I was replacing due to age and poor performance.

Photodude i know how it goes - - me too i work under the hood with that little elbow in the back of my mind .
But cheaper to replace than a radiator . I have three of these little critters as spares just in case i slip up one day.. But the alum radiator sure is worth thinking about if you can get one for your car..

I developed a hairline crack on the upper hose neck on both my 98 SL500 and 99 Sl600. Kept seeing the white crap in the engine compartment and couldn't see where it was coming from till I borrowed a pressure tester. The cracks were just inside the hose coverage.

I actually broke off large neck while removing upper radiator hose on W124, that's why I'm always mindful this could happen when those plastic fittings are old enough.

I don't think I've ever seen that but, radiator getting old and anything can happen I guess. From my experience, I would not have an issue putting in another Genuine MB/ Behr radiator but I'm very open to upgrade to All Aluminum.

Best prices I found are: Genuine MB = $363.40, CSF = $430.53, Liland 1314AA = $249.79

What's the difference between CSF and Liland?

All I can say about that is the Liland is a quality radiator. I have made a lot of oil tanks and coolers for race cars in my younger days and the welding on the radiator is excellent. I have 10k on mine and make monthly trips to NV and AZ, no issues. Maybe some one else can attest to this also

Yup.
If you get lucky, you can find the liland on APW for less than $200US . I have no issues with mine with a few thousand miles on it now.
