   Serpentine belt (foreground) and dual vee belt (background) on a bus engine Belt tensioner providing pressure against the back of a serpentine belt in an automobile engine. A serpentine belt (or drive belt [1]) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air ...

3. Timing belt (camshaft) - Wikipedia

   en.wikipedia.org/wiki/Timing_belt_(camshaft)

   Timing belts are typically located in front of the engine and are often behind a cover for protection against dust and debris. However a few engines since 2008 have used "wet timing belts", whereby the belt is lubricated by engine oil to reduce friction losses by 30% and thus reduce fuel consumption by 1%. [7]

4. Tensioner - Wikipedia

   Chain tensioner on a single-speed bicycle Belt tensioner on a belt-drive bicycle Hydraulic bolt tensioner Hydraulic Puller-tensioner . A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring ...

5. Belt (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Belt_(mechanical)

   A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need not be parallel.

   According to GM, "the crankshaft is shortened 13–3 mm (0.51–0.12 in) at the flywheel end and 10 mm (0.39 in) at the accessory drive end – to reduce the length of the engine compared to the 6.0 L. All accessories are driven by a single serpentine belt to save space.

7. Chevrolet small-block engine (first- and second-generation)

   The large-journal connecting rods were thicker (heavier) and used 3 ⁄ 8 in (9.5 mm) diameter cap-bolts to replace the small-journal's 11/32. 1968 blocks were made in 2-bolt and 4-bolt versions with the 4-bolt center-three main caps each fastened by two additional bolts which were supported by the addition of thicker crankcase main-web bulkheads.

8. Bolted joint - Wikipedia

   en.wikipedia.org/wiki/Bolted_joint

   Bolt preload can also be controlled by torquing the bolt to the point of yielding. Under some circumstances, a skilled operator can feel the drop off of the work required to turn the torque wrench as the material of the bolt begins to yield. At that point the bolt has a preload determined by the bolt area and the yield strength of the bolt ...

9. Chevrolet Cobalt SS - Wikipedia

   The Stage 2 kit consists of new fuel injectors and the same reprogram with a smaller serpentine belt and pulley for the supercharger, producing a 36 hp (27 kW) improvement and 18 lb⋅ft (24 N⋅m) of torque. Both stage 1 and 2 kits increase the engine redline to 7,000 rpm. [12]
