Except for timing belt driven pumps, then replace when you do the belt.

My take is if you do a system flush, the water pump will start leaking after one month. Been there, done that!

The water pump might not be a maintainance item for you but it is a maintainance item for your engine. It ain't broke until it's broke and you're sitting on the side of the road with an overheated engine.

I don't think the radiator on the e320 is inadequate. Having a larger radiator isn't always a good thing. If you are doing something that stresses the engine like towing or racing, etc then you DO want a larger radiator. But a radiator that's too large for the engine means the engine is going to struggle to maintain the proper operating temperature and that's not good either.

Remember Mercedes have been using the same engine and radiator since 1998 in the W210. So they believe the setup is fine.

Per my experience MB designs cooling system for pulling 2 tons trailers on Sahara desert in triple digits temperatures and driving E300DT with engine fan removed proves it.
But I am religious on using MB only coolant.
With water pumps you just never know.
Sure when you are doing other jobs, replacing the pump at 250,000 miles might be reasonable, but as pointed above -failing bearings will give you some warning with drip.

They didn't use the same radiator on the W210 E320. That radiator core is 32mm thick. I've worked on a lot of MBs and I've never encountered a 16mm radiator core before this 04 E320. I'm not sure how a 34mm radiator core could "over cool" an engine with a functioning thermostat but I'd love to hear more about that theory.

E300 diesel has a 40mm radiator core from the factory. But I've got this fancy new and improved 16mm radiator just gathering dust in my garage. I think you should try it in your fanless E300. Its no thicker than your AC condenser. I hear it does wonders for your engine's cooling system.

LOL

For radiators it is frontal surface and number of rows that counts for heat exchange.
Obviously thicker radiator might indicate more rows, but not necessary.
I also did remove the only fan on Fiat 125 and drove it just fine without it.
But that was in Poland, where we did not see triple digits temperatures.
So once again, I never had any signs of MB overheating even I routinely drive in temp above 100F and some of my cars had high 200's thousands miles. .
I prize MB coolant for high efficiency and used it even in my trucks.
First result was that truck engine visco fan stop coming on in city traffic. Those fans were over 20 hp rated, so you could definitely tell when they are on.
That not only made driving more comfortable, but saved fuel as well.
Consider that before trying to save 5 bucks on Zerex

Actually you forgot about total surface area. Oops.

But if you really think it's all about frontal area but all means the 16mm radiator is ready to go.

The same reason why people that live in extremely cold climates block off part off their grill or radiator. Too much cooling is not good. The thermostat won't be able to keep up with the extra unneeded cooling.

How do you explain the E320's not over heating? If the radiator was too small then why hasn't anyone had a problem?

Apparently the expansion tank is lovingly referred to as the 'explosion tank' by the auto techs. Eventually they'll just burst from the constant expanding/contracting with the heat and pressure, etc.

Should be all set for at least another 15 years, I guess. I suppose it's definitely suggested that if you're replacing the radiator just go ahead and do all those other items as well so you don't need to go back and drain/refill and replace the expansion tank when that decides to go.

Hopefully that was the largest repair bill I'll have to deal with for some time.
Horrid! Only 15 years. Should last 30 years or more with other than annual coolant changes and occasional coolant hose replacements. No reason for the radiator or expansion tank to have failed that fast unless you've been filling it with salt water.
