Have Toyota Questions? Ask a Mechanic for Answers ASAP
Did you actually replace the drive belts yet? If so what brand of drive belt did you use? How many miles are on the vehicle? Are you noticing any power steering leaks or have you had to add fluid to the power steering reservoir? How old is the battery?
Approximately how many miles and months have the drive belts been on the car? Is the plastic shield installed that goes on the inner fender and hangs down in front of the engine on the right side of the inner fender well?
At this point we can probably rule out any issue with the power steering pump or the fluid. It is not recommended to spray lubricants/dressing on the Toyota belts. This engine particularly is difficult to stop that initial squeak of the belts. I have had multiple issues with aftermarket belts like Goodyear and so on. It's possible that you have gotten the belts contaminated at this point. When installing the belts especially the power steering belt it has to be extremely tight. Almost to the point where you get virtually no deflection between the two pulleys when pushing in on the rubber belt. The alternator belt itself doesn't need to be quite as tight as the power steering belt but however if you are getting an additional squeak on the belts after startup this is caused by the alternator charging to recover the battery after the initial draw down on the start up. This just means the belt needs tightened up a little more. However again if the belts are contaminated at this point by putting spray additives on them normally they will have to be replaced. Before you replace them I would get some brake cleaner from your local parts store and with the engine running spray the brake cleaner on the drive pulleys at the alternator power steering pump and the main crank pulley it will dry very quickly but this will remove any contaminants from the pulleys. Then tighten the belts up extremely tight more than you would normally think they needed to be and see if the squeak goes away.
You are welcome. If that still gives a little noise you may have to replace them again,
On this particular year the drive belts were notorious to make a chirp sound after initial startup. I have owned two of these. They both did the exact same thing I got it down to almost nothing with the exception of one light chirp after startup. I was only able to accomplish this by putting the belts extremely tight and they were Toyota belts.
