How to replace belt idler pulley on 2002 seqouia

Troublkeshoot possible noisy idler pulleys, if they are OK, remove the plastic cobers & check for a noisy timing belt tensioner pulley. Water pumps rarely "whistle"; they grind. But, if you see any evidence of leakage at the weep hole on the water pump impeller shaft, replace the pump regardless. Might as well replace the timing belt whilst you are there, too.
