Tips for the Thermostat in Case of Engine Overheating

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Thermostat

This video provides some tips regarding the proper functionality of the thermostat in a BMW 5 Series. The thermostat is the valve that opens and closes depending on the temperature of the coolant, allowing control of the engine temperature. Due to its important function, it is not advisable to replace the factory-installed part with a low-quality one. When the coolant temperature is correct, the gauge on the dashboard (with the engine running) should be positioned around halfway or slightly above it. The advice that the video author repeats multiple times is to never buy a cheap thermostat!
