I wonder if you can help.
I have just discovered that on the top radiator hose of my 2005 Gti (manual) there is a screwdriver handle being used to bung up the lower output of a large "T" piece in the top radiator hose.
I discovered this whilst trying to find out the location of the dreaded inline thermostats.
Does anyone else have a large plastic "T" piece in their radiator top hose and if it has a hose coming from it - where does it go please?
