2005 Suzuki XL-7
The first-generation XL-7 is built on a stretched version of the full-frame platform it shares with the Suzuki Grand Vitara. Designed to be a small SUV with three rows of seating, the back row is definitely for kids only. The 2.7L engine's power is relatively modest for a 3,700-pound vehicle, but the part-time four-wheel drive with a two-speed transfer case makes this a relatively capable off-road vehicle, and its small size could be a real asset. Like other Suzuki models, the XL-7 offers a lot of features for the money. The truck was completely redesigned for 2007, and the second-generation model is built on the GM Equinox platform.Suzuki also built a 2.5L version of this engine, but the specs are different. Specs given in this article are for the 2.7L engine only.
There are quite a number of drive chains on this engine. A large chain from the crankshaft drives an intermediate reduction gear on the bottom of the left cylinder head and another on the right intake camshaft. A double-row chain from the right intake cam drives the exhaust cam, while another double-row chain from the left intermediate gear drives both left camshafts. Another smaller chain from the crankshaft drives the oil pump. Consequently, this engine has a lot of sprockets and chain tensioners. Fortunately, the water pump is belt-driven.Ignition timing can be adjusted by turning the cam position sensor on the back of the left cylinder head, but first the PCM must be set to fixed-timing mode using a Tech 2 scan tool.
This is not a low-maintenance vehicle. Pay attention to fluid change intervals and fluid types. The rear axle requires a different lubricant, and that difference is important to the longevity of the gears. For coolant, Suzuki specifies ethylene glycol with phosphates.Suzuki doesn't release many service bulletins, and the only significant bulletin for this model says that engine noise that sounds like a rod-knock may be caused by an over-tightened alternator belt.
