Narrative:

I was pilot flying. We were being vectored for an extended final approach. During one of the turns; I noticed that the engine 1 oil temperature was boxed red and was indicating around 130 degrees. I pointed it out to the captain. The captain ran the QRH for engine high oil temperature. The first two items in the QRH say to reduce thrust on the affected engine; and to maintain the temp within limits. Thrust was initially pulled back some; but not to idle; and the temp continued to climb. Thrust was then pulled all the way to idle. The temp continued to climb. The QRH then goes on to say that if the limits cannot be maintained; a precautionary engine shutdown should be performed. With the oil temp continuing to climb with idle thrust; we agreed to shut down the engine. I saw the oil temp reach 144 degrees around the time the engine was shut down. The captain performed the engine failure/precautionary engine shutdown procedure and the one engine inoperative approach and landing procedure. When the approach controller switched us over to tower; the captain then [advised ATC]. We landed and cleared the runway; where emergency equipment was waiting for us. We then taxied to the gate and notified maintenance.a threat was having to perform multiple QRH procedures in a high workload environment; but due to the vectors and long final; there was adequate time to accomplish the necessary procedures. Another threat was having to perform a single engine landing since it is not something that occurs often.
