Can you tell me whee to find the thermostat on a bmw 316i aoto k reg

Hi,
If you are referring to the coolant thermostat, though I'm not familiar with your model, basically thermostats are located in a housing on the engine where the top radiator hose connects to that housing. For the most part, they are pretty easy to replace. If you have an overheating problem with your car, I hope this fixes it.
