We have a 2008 Sienna with the 3.5l 2GR-FE V6, with 195,000 miles. Lately we have a chirping noise under the hood, in the area of the drive belt tensioner and the No. 2 (right) idler pulley. The other night, while the engine was idling, I touched a Phillips screwdriver to the bolt on the No. 2 idler puller, and the bolt for the tensioner. The No. 2 idler pulley was smooth, while the tensioner was rough.
The tensioner (p/n 16620-31040) for the 2GR-FE includes the pulley, the tensioner, and the bracket, which has five bolts which face the front. The bolts are behind the a/c compressor, which would have to be moved for clearance.
My question is, can the bolt on the front of the tensioner be removed, and the pulley be replaced separately? I have found a part number (16603-31040) for the tensioner pulley by itself.
Has anyone out there changed the tensioner pulley without the rest of the tensioner? The torque value for the No. 1 and No. 2 pulley bolts is 32 ft-lb, so is it the same for the bolt on the tensioner pulley? The bolt on the tensioner pulley is the one used to move the tensioner, to remove tension on the drive belt for removal. My plane is to replace the drive belt, the tensioner pulley, and the No. 1 and No. 2 idler pulleys.
