Jim Bowen 1 Posted November 14, 2012 Just started up the corrado after 18months and lots of new parts. I let it sit on the drive and warm up, the coolant warmed up fine. The oil temp went up to about 70c then i noticed it falling all the way down to 52c then slowly back up again? I'm sure i'd never noticed anything like that before? Where is the oil temp read from?
