That doesn't look too bad. On my '96 Bonneville the serpentine belt actually runs through an engine mount. You have to jack up the engine a little and take the mount apart to get the belt through it. To do that you have to remove a tire & part of the inner fender & sit under the wheel well. The Taco looks pretty simple by comparison.
