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 ...
The main disadvantage is that belts wear over time, therefore belt replacement is recommended at specific intervals. [5] [6] Replacement of the engine's water pump at the same time is often recommended, since the water pump is also subject to wear and easily accessed during the replacement of the timing belt.
Belt replacement is an obvious solution, and eventually the mandatory one (because no belt lasts forever). Often, though, before the replacement option is executed, retensioning (via pulley centerline adjustment) or dressing (with any of various coatings) may be successful to extend the belt's lifespan and postpone replacement.
A timing belt is used to drive the valvetrain. Early production 2.0 L engines used a hydraulic tensioner to tension the timing belt. 2000 and 2001 engines used a mechanical spring-loaded tensioner that tended to wear out prematurely, causing serious valve and piston damage upon belt failure due to the interference design of the engine. 2002 and ...
From 1987 onwards, the LB4's output was 160 hp (119 kW) for pickups, while full-size vans were rated at 150 hp (112 kW). In 1988, the S-10/S-15 trucks, S-10 Blazer, and S-15 Jimmy had the LB4 4.3 L (262 cu in) as an available option (the accessory drive was upgraded to a serpentine belt drive), which later replaced the 2.8L as the base V6.
The compressor can be driven by the car's engine (e.g. via a belt, often the serpentine belt, and an electromagnetically actuated clutch; an electronically actuated variable displacement compressor can also be always directly driven by a belt without the need of any clutch and magnet at all) or by an electric motor.
The Oldsmobile Diesel engine is a series of V6 and V8 diesel engines produced by General Motors from 1978 to 1985. Their design was based on the Olds 350 gasoline engine architecture.
M272 engines that were sold between 2004 [1] [2] and 2008 with engine serial numbers below 2729..30 468993 often show early wear of the balance shaft gears, requiring extensive repairs at a retail cost of over $4,000. [3] [4] These complaints led to a class action lawsuit against Mercedes-Benz (Greg Suddreth and Paul Dunton v. Mercedes-Benz USA ...
