Have a 91 300E 4MATIC. The outside temp. right now is around 5 degree's C. Car is running at 120 degree's C with a short 5 minute run around the neighbourhood. The fans on both sides of the radiator (fore and aft) are working. When i turn the car off i can hear fluid noise from the radiator, does that mean the fluid is still circulating. In an ideal environment where the radiator is full of coolant isn't it impossible to hear the fluid circulate in there because it should technically be full of fluid?
Since the fluid is still running i dont think it's my water pump, i dont see steam so i dont think it's a leak in the hose.
What the Hell can it be?
(I will check the oil when the car cools down)
