Aftermarket oil cooler for om606. Sandwich plate necessary?
What you are asking isn't entirely clear. The oil filter block has a built in thermostatic switch. There were a number of different oil filter + cooler designs for the OM606a. If your filter has hoses, then the flow should already be thermostatically controlled. The factory coolers seem well sized for the oil line size. Adding a bigger cooler may not make much of a difference. You could add a more powerful fan if you think that the cooling is insufficient.
