Thermostat problem...

I have a R 25, 1994cc, diesel, year 2000 ... my thermostat is in oil cooler ... and it's tiny open and it's warm up verry slow...



How can i bypass that oil cooler? I understand that many R 25 don't have this oil cooler ....



Or, ... if i remove the thermo from that oil cooler and i pun an old model of thermo in the hose that go to oil cooler...could it do something wrong to my car?



p.s. I attach a link of an old thermo...to see what i am talking about....
