Need to Know Which Oil Port is In & Which is Out?
Question I have is - which of the two ports in the block behind the adapter would be the 'engine out' and which is 'engine in', or doesn't it matter?
Only reason I am asking is because the ports on the thermostatic control are specific as to which is 'In' and which is 'Out'
So looking at the adapter, is the front hole (toward front of car) or rear hole (toward passenger compartment) the 'Out'?
is your setup like this?
My adapter also has the seperate port already drilled/tapped for the oil temp sending unit.
