Do you know how the oil is distributed to the oil cooler on a tdi engine?
What is the valve thingy in the top of the oil filter housing?
Does the oil always circulate through the cooler, being initially warmed by the coolant water , then, cooled by the coolant water?
Or
Does the valve thingy open when the oil reaches a set temperature sending oil to the cooler?
(or is the valve thingy just a bypass if the oil filter gets blocked?)
Reason for asking, Im sticking with the standard series II radiator on my tdi conversion, so am forced to fit an aftermarket oil cooler, but am concerned about overcooling the oil? And wonder if a cooler is even necessary up here in Scotland?
My thoughts had been to fit two shut off valves in the cooler lines, so for winter running (and probably most of the summer?) the pipes would be blanked off, then on the odd hot day, open the valves and let the oil circulate through the cooler?
But how is the oil pumped, will closing off these ports cause a problem for the oil pump, forcing oil down a dead end pipe??
Any help gratefully appreciated
