Nov 6, 2021 · The Electronic Coolant Pump is a Brush-Less Direct Current motor - BLDC motor. The stator rotating magnetic field is coupled to the rotor pole pieces through the metal can. A MOSFET network provides the electromagnetic rotating field at the command of a Pulse Width Modulated signal from the ECU DME/DDE. That is the source of your 246 RPM signal.

I had an issue the other day with a temp sensor on the thermostat being partially backed out of the connector and providing an intermittent connection.

The hot liquid enters through the upper part of the radiator, and it comes out being cool from the bottom part. In order to keep its good performance, the engine of your E70 must always stay within the optimal temperature range, which is usually around 190ºF (90°C).
