Hi Guest !
Welcome to the 500Eboard forum.
Since its founding in late 2008, 500Eboard has become the leading resource on the Internet for all things related to the Mercedes-Benz 500E and E500. In recent years, we have also expanded to include the 400E and E420 models, which are directly related to the 500E/E500.

Oil cooler options
- Thread starter Jord

Remember there is a thermostat inside..which opens at 100 or 110,degrees,and fully opens at 125 degrees(oil temp).So the oilcooler circuit is "rarely" in use..i would dare to say never..unless you are tracking the car..or live in an extremely hot climate.
Here is a video i did..and you can watch it from 10min 30 sec..and you will see the thermostat.

I haven’t looked recently, but IIRC it doesn’t even start to open ‘till 115°C. They do nothing other than in long autobahn driving in the summer near top speed, HARD Alpine climbing with a full load of passengers and luggage, and/or pulling a trailer at high-speed. With with modern synthetics, it’s completely pointless. That is also why they have largely gone away even in the highest performance modern cars. In fact, most modern cars use an oil to coolant heat exchanger so that whichever one is hotter at the time can HEAT the other. Efficiency, you know. Thermostatic control is a must. Oil that is not hot enough is EVIL...
Most, but not all RENNtechs... depended on the customer.
Don't know about Brabus.
Yes, all AMG E60 builds had the coolers, because all were Euro spec. All 5.0L 036's worldwide got the cooler EXCEPT for USA and Japan.
As Klink mentioned, it likely won't open the thermostat to do anything without extended load (i.e., Autobahn, Silver State Classic, or extreme ambient temps).
I'm not certain, but I think without the thermostat present, you'll end up with full-time oil cooling... which could result in the oil coming up to temp slowly.
I've never heard of anyone drilling open the casting areas as you are planning to do, so I'm not sure what will happen. I'm assuming you don't want to s hell out $$$ for the proper housing with thermostat?
No lol. I'd rather build something myself. I live in Florida and have the exhaust running under the oil pan, oil temp rising slowly wouldn't be an issue. This car is the definition of a heat pump lol.

I'd add a screen over the external oil cooler... don't want a stray rock to punch a hole in it, and dump all your oil out. Especially since MB has no warning light for zero oil pressure, and the low oil level warning doesn't trigger for 60 seconds.
I would think your best bet is to source a used Euro Oil filter housing with the T Stat already inside to ensure proper function. However as Klink has noted the stock setup will see very little (to zero) actual use of the Oil Cooler.
What I would be very dubious of is the functionality and oil flow if you drill the casting on the current non oil cooler housing. The reason I say this is that I recall seeing holes inside the T Stat bore which means the Oil flow circulation and pressure may not function correctly by simply omitting the T stat. EG: I believe the T Stat has more functions in diverting Oil flow than simply restricting it.

Mkay, I'll keep my eye out for a euro housing then. If I can't find one then worse case scenario is I use the scavenge pump I have laying around to make something. Also, this car produced and stores a lot of heat. Opening the thermostat won't be an issue here in Florida with a turbo V8 all packed into a small car.

Also, I'm tired of the sleeper look. I want to give her some aesthetics, like a visible intercooler, mild drop, the new wheels I have, and an external oil cooler.

Exactly!
