Question How do I replace the water pump on a 1993 Lexus SC400?
Answer REPLACING THE WATER PUMP INVOLVES REMOVING THE TIMING BELT. IN THIS PROCEDURE, A LOT OF COMPONENTS NEED TO BE REMOVED EVEN BEFORE THE WATER PUMP IS REMOVED. THERE IS HUGE POTENTIAL FOR PROBLEMS WITH THIS REPAIR. THE GOOD THING IS THAT THIS MOTOR ON THE 93 IS NOT AN
INTERFERENCE MOTOR. IN OTHER WORDS, IF THE TIMING BELT WERE TO BE INSTALLED INCORRECTLY, AND THE VEHICLE WAS STARTED. IT WOULD NOT CAUSE INTERNAL DAMAGE.(EXAMPLE)BENT VALVES.I WOULD ADVISE YOU TO HAVE A EXPERIENCED TECHNICIAN PERFORM THIS REPAIR.GOOD LUCK
