For #17 I would say while your checking/changing your belts remove your crank sprocket and the balance shaft sprockets to check your oil seals. Chances are youll be the first to do so since the truck was sold off the lot.

For #6, is there a specific year of Montero I should get a fan shroud from? I'm looking to put it on my 82 D50, 2.6L 2wd.
