Narrative:

Climbing through FL180; the left engine oil strainer clogging light came on. We reduced thrust slowly all the way to idle trying to get the light to go out per the QRH procedure. Since it would not go out; we complied with the QRH and shut down the left engine. Also told ATC and declared an emergency asking to go to ZZZ and land. At time of shutdown; the left engine oil temperature was 130 degrees C. We coordination with the flight attendants and I talked to the passenger. We notified dispatch. Landed uneventfully at ZZZ in gusty winds and had the crash fire rescue equipment folks check the engine over before we taxied to the gate. Time airborne with single engine was 30 mins. Thanks to the first officer for his well done assistance and help as well as the flight attendants and ATC. We were given another aircraft and continued on to destination arriving about 2 hours late. Landing weight at ZZZ was 118000 pounds.
