Question about 1991 Toyota 4Runner

1 Answer

Instillation of bracket idler also known as fan pulley bracket of 1991 toyota 3VZE motor.Part is bracket sub assembly OEM part #16307-65020. I removed the part after I changed my water pump and timing belt. I ran the truck when the pulley on this assembly froze I removed the part dis assembling the radiator, fan, timing belt cover and loosened the belts and such. I went to toyota and found that the part cost almost a $1000. I tried 3 different after market products but the bolts never matched up. I finally bought the OEM part after saving for the last 8 months. Problem is if I pull it apart and put it back then I can do it However so much time has transpired I am not sure how everything goes back exactly. If I had a blow up diagram I think I can do it but at this time I dont want to ruin anything, Please help if you can Thank You Paul

Idler pulley bracket where can I buy one or is there an alternative to it


you need to post year, make, model and what engine?
also which idler pulley? I'm guessing you're probably looking at the accessories drive belt ("fan belt") idler pulley bracket.
Is this a serpentine belt.
a lot of cars use Idler and or tensioner pulleys on the timing belt/chain. the Idlers often don't have brackets
why are you replacing the bracket? did you break it? or do you just need the pulley? I normally replace both pulleys (idler and tensioner) when replacing either one.
anyways.. need a lot more info to answer your question

Power steering belt on 1991 toyota camry


Locate the idler pulley. Loosen the nut in the center of the idler pulley. Then loosen the bolt that protrudes from the back of the pulley. This will let the belt go slack.
