W123 300d radiator advice?

Post by yumcha » Sat 20 Jul, 2019 1:56 pm

The radiator on my 1980 300d needs to be replaced.

I can get a 300d radiator for a decent price, but other rads are cheaper.

I know the 240d radiator fits fine, but does the 230e or 280 rad? As I thought they were the same as the 240d.

Thanks!

The 240D radiator is not a wide but should be OK if you don't use air con (my english 300TD had one till I replaced it)
The 230E radiator is not as thick so will struggle to get you the cooling needed in summer
The 280E radiator does not have the slots for the Oil Cooler to be bolted alongside

Ok thanks! No I don't use it and pulled the belt off.

The 300d radiators I see online seem to have two holes on the bottom for coolant (one for the lower hose, and one for a smaller hose next to it) plus the two auto trans lines. But my car just has the trans lines and one hose at the top and bottom. Like a 240d.

That radiator is for the Turbo Diesel as it has the overflow tank. You can fit it, but will need to get the tank and 2 hoses hose to the radiator from a W116 or W126. I fitted one.

Sounds like the 240D is the simplest to fit. The diesel radiators are getting harder to come by - are you sourcing from the net somewhere ?

Yeah just from eBay...

The 280e radiator will fit and is the right size, though I will have to relocate the oil filter. That might be the best choice...

My sons 300D had a 280E radiator fitted and the oil cooler deleted as it couldn't sit along side. I put a proper diesel one into the car and put back the cooler.

A new 280 radiator is I believe becoming rare new

John Green assisted me in 2 x new ones over the last 10 years through a wholesaler in Melbourne.... 1st one JG organised within 24 hrs to my door in about 2015 after broken plastic top neck

2nd one JG put me directly onto the same wholesaler directly in 2016...idiot me holed the 1st whilst changing belts
The 2nd one lasted about 6 months before leaking between the header and core...(both were Behr brand so not cheap crap)

I bought the 3rd one in October 2018....the wholesaler(who sometimes wont sell direct) said they were no longer listed...
I bought the 3rd one from Mercbits in Huntingdale as it was a cancelled order...needless to say I bought it very quickly
Again another Behr

So act quickly...anyone else had similar experience in supply issues ?

You can't get BEHR / Hella anymore unless it is new old stock. There are Nissens and others around. For the 300D, it's near impossible and the US Turbo versions are getting scarce as well.

I recently bought two from Northside radiators and auto care,

11/209 Robinson Rd East,
Geebung Brisbane
QLD 4034

07 32162000

after having trouble finding a supplier. They are made somewhere in Asia but a perfect fit for my 300d automatic paid $330 each. I have done close to 50,000km on my daily since without issues.

Good information right there :)

I always thought that once spares dry up we'll have to go the hotrodders route and get custom brass/copper ones made up or something.

Thanks - that is really good info!

My step-dad owns a merc mechanics in Byron and still couldn't get one from his supplier.

UPDATE: If anyone cares, I ended up getting a $200 eBay one for a 240d/some 300ds... It's a little narrower but fits perfect. So far runs at exact temps, but I'll see what happens in summer. I pulled out the AC radiator (since it doesn't work) to get extra airflow.

In retrospect, a custom brass tank radiator would have made more economic sense than the plastic rubbish, including Behr with 3 x radiators in 9 years......I had a custom one made/repaired when I had an Austin Healey Sprite back in the late ‘90’s... the only English car owned that never leaked oil or water 😂😂😂
