Idler pulleys
I am needing to replace the two idler pulleys (and the tensioner pulley as well). I am finding it difficult to find the idler pulleys....Does anyone have any suggestions where I can find them ?

Thanks

The idler by the Alternator = unit off an H3 Hummer works, Idler Pulley = you can get a nice metal replacement by Gates. Other idler below the A/C compressor = not sure of, as I just order OEM replacements from AB or Lucky8.

Hi, I bought the Dayco 89287 automatic tensioner assembly and the Gates 36301 (H3 steel pulley). So now onto the driver's side and the Gates 36275 ?? Amazon says it will not fit..... Sorry to be so daft. Being North of 49, I only order from AB or Lucky8 if the bill is over a Benjamin. Thanks. Cheers,

order from AB and save the headache
Ok, I note the shape/size of the bushing of the pulley results in a 10 mm loss of bolt length. Did you put another bolt 10 mm longer or do with the OEM one from the old unit? (I note there would be about 10mm of bold instead of 20MM thanks.
