Man, your car's bottom is filthy, you ever pressure wash it?
Just kidding, it just doesn't match the flawless topside.

My 05 E55 has 3900 miles on it and it runs 80 C on the temp guage. This may sound too basic but here is my two cents on a couple of easy things to check out. 1. Any coolant mixture greater than 50/50 mix of antifreeze to water is less effiicient. A lot of people think adding more antifreeze to the water makes it better. It actually makes it worse at removing engine heat. 2. If you use anything other than distilled water such as tap water and it has a lot of mineral content it will plug the bottom cores of your radiator almost like hardening of the arteries. I have seen radiators completely plugged using hard tap water with a high mineral content. That will reduce the efficiency of the radiator. 3. The obvious one you already mentioned would be to test the thermostat and see when it opens. It may be sticking and only partially opening. Again could be due to tap water.

I'll give that a shot once they check my water pump and thermostat.

Hi Victor,
On the LS1 Chev engines, colder operating temperature thermostats are available to lower the engine running temp. I do not know if a range of different operating temp thermostats are available for the Mercedes engines, but if they are this would be a simple method to alter the operating temperature of your engine.
In my previous HSV's (Holden Special Vehicles) I found the best performance was obtained by using a 84 degrees Celsius thermostat.

Victor,
Did a quick search and found a 87 degree Celsius thermostat available for the E55 (pre 2003 ie; non supercharged). If one is available for your engine it doesn't cost much to try it out.

Hope this helps,

I had a C5 vette also.. When I first got my E55, I started looking for all the little things that I did on my C5... I wasn't too surprised to find out that these simple things weren't available.
If I knew the manufacturer of the thermostat I could probably source a lower temp one, but, as it is now, I can only get the factory replacement.
