Yes a themostat should be used when running an
oil cooler. Cooling the
oil too much can create problems. The thermostat will by pass the cooler if not upto temp.
Put the
oil temp sensor tee on the fitting that comes straight out of the engine.

Remote Oil Thermostat
Maintaining proper oil temperature is critical and the installation of an auxiliary oil cooler helps keep the oil below the 190 deg. F maximum temperature. Installation of a remote oil thermostat, in addition to an oil cooler, provides faster warmup to operating temperatures. When oil temperatures exceed 180 deg. F, the thermostatic valve closes allowing full flow through the oil cooler. At temperatures below 180 deg. F, the valve is open with 90% of the oil bypassing the cooler. The remaining 10% of the oil flows through the cooler to maintain constant system pressure and prevent air pockets in the cooler system. Flows up to 20 GPM at 200 psi. Has 1/2" npt ports.
