The smooth-faced idler the accessory belt runs over — the silver one. There are two idlers on the front of this engine and they are different parts: this one runs on the flat back of the belt, the other is grooved and runs on the ribbed face. Order by face, not by "idler pulley", because both will come up under that phrase. A dry idler bearing announces itself as a rumble that changes with engine speed and not with road speed, and it is worth catching early: a seized idler shreds the belt, and the belt drives the alternator, the water pump drive and the power steering. The number, the fitment and the count come from the Montero specialist's own catalogue page, cited below — a parts catalogue is good evidence for what a part number is and what it fits, and it is not factory literature, so read every figure on this page as the catalogue's claim rather than as a service-manual specification.
Aftermarket cross-references
| Brand | Their number | Verdict | What we know |
|---|---|---|---|
| Koyo | PU159026RR1HY6 | Same maker as the OEM part | The catalogue states that Koyo makes the drive belt pulleys for Mitsubishi, and sells this one in Koyo's own box at a lower price than the Mitsubishi-labelled packaging. Same part, cheaper label — the useful kind of cross-reference. |
