Hi all i have a bmw e46 328i just wondering what the sensor is in the bottom of the radiator hose ive also noticed that the bottom pipe is colder then the top pipe
hope someone can help
I think this may be a double post, but just in case it isn't, the sensor is a temp. sensor. Also, you may want to swap out the thermostat because it sounds like it is not opening when at running temperature.
