  Summary

  3-way valves are available in STAR Parts as two distinct components and must be selected correctly based on application. The High Temp 3-way valve (68309834AC) is located between the engine and the bulkhead at the rear of the engine compartment. The Low Temp 3-way valve (68448241AA) is located between the engine and the radiator at the front of the engine. When ordering or servicing, ensure the correct valve is identified and installed in the proper location, as incorrect part selection may lead to improper thermal system operation and repeat repairs.
