General
The IBT leaves the bypass channel open
so that a part of the  uid bypasses the
cooling element. Only when the  uid
temperature reaches the required value,
the IBT closes the bypass channel and
the  uid is cooled down. So, a too low
temperature of the  uid can be avoided
i. e. at cold starts.
Note:
This valve requires a special cooling
element with integrated bypass channel.
Therefore, it cannot be retro tted.
