Question about the original Oil Cooler

[sonny]

Hi

I have upgraded my Oil Cooling System with a 9 Row Oil Cooler, With Adapter on the Oil Filter Flange.

I leave the original Oil/Water Exchanger where it is, but disconnected the Water Hoses from it, Because my Wastegate of my new Turbo had a Collision with it

I Have a turbopressure and Water Temeprature Gauge- Everything is OK so Far. But i have NO Oil Temperature Gauge.

What do you think ? I Am worried about high Oil Temperatures (1. Because the original Water/Oil Exchanger doesnt work anymore because i removed the Water Pipes from it, and I Hope that the 9 Row Oil Cooler is Enough to Cool the Oil)
My Oil Cooler had a Thermostat in it :-) (So it should warm up quickly)
I Don´t want to blow the Engine with to High Oil Temperatures ...

Greetings
Red Marked Hoses are Removed by me.
