Unusual oil temperatures and oil behavior - 08 S65 142K miles / VAC / CSF Rad

Do you happen to have a link for that part ?

Look like you have fixed it. Clearly if the oil cooler was always cold, your oil and, by extension, your coolant, was always hotter than it should be. Your current numbers look perfectly normal now. Good job on the fix!

But like tdott said, it might be useless if you can just remove the spring and cap it back without a valve or thermostat.

So should the engine oil cooler always feel warm/hot to touch when the car is fully warmed up? Many thanks.
