My manual 2.0 v6 has the oil cooler . I too am unconvinced about the need for it. There is a thread on here somewhere about a member doing his cambelts and I commented that the pics didn't show an oil cooler . Turned out a previous owner had removed and bypassed it , and the car was running fine without it
The thread is here

, but unfortunately the OP has removed his content and replies ( presumably due to a dispute )
