Question about Mercedes-Benz E320
Thermostat is probably bad.
Without knowing what year your car is, the thermostat could be here:
.To test the thermostat, put it in a pot of boiling water. If it clicks, it works. If not, then replace it.

1. start the engine and leave the radiator cap open.
2. put a cardboard cover or a rug in the front of you radiator.
3. let it runs 20 minutes or more, see if it is overheated and see the water or coolant in the radiator circulated or not. If not, as soon as you have already changed water pump. thermostate and check the hoses, no leak, I think your radiator was blocked.
Did you put stop leak before?

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

you could have a bad hose, check the upper and lower hoses and hake sure they are not caving in on themselves. sounds like it could either be that or you might have something cloging the hoses. run the engine with the hood open so you have the pressure build up, and look at both raditior hoses. see if they are bulging out as pressuer gets built, or if they cave in .

SOURCE: engine overheating
The same thing happened with my 01 cavalier. My dad replaced the thermostat and it did the same thing. Then he discovered that there is something called a temperature control sensor that had to be replaced because when the thermostat froze open, it destroyed the sensor. It was a lot cheaper than any of the other parts and once it was replaced, it worked fine.

To start with you have to do this:
With the engine cold, start the car and say after 30 to 40 secs. open the radiator cap.
Carefully and slowly, cause if the problem is either in the cylinder block or cylinder head this shows immediately as water would be compressed in the radiator ( even though the motor is still cold ).
If nothing happens and you would not notice any bubbles in the radiator, then we have to talk again.
