Voltage Regulator


Asked by Jun 25, 2012 at 12:18 AM about the 2002 Toyota Celica GT

Question type: Maintenance & Repair

I own a 2002 Toyota Celica GT 1ZZ-FE engine.  I was told that my voltage regulator was going bad
today by autozone.  Do I need to replace the whole alternator or can i just remove the voltage regulator
from it and replace it?  

1 Answer


Hi, you can replace the regulator but it means disassembling the alternator, the best and easiest option for yourself would be to buy a good second hand or even reconditioned alternator from somewhere, I work for TCB Performance Parts LTD and we've been specialists in Celica's, Supra's and MR2's for over 25 years! :D
