What is a Serpentine Belt and How Does it Work?
A serpentine belt is an important component in any vehicle, including the BMW X5. It’s named serpentine because it snakes around various pulleys to power different systems that need mechanical energy from the engine. It’s also called a multi-ribbed or poly-v belt because of its several grooves on one side.
The serpentine belt connects the alternator, water pump, air conditioning compressor, power steering pump, and in some cases, the supercharger or camshaft. Therefore, if there are issues with your BMW X5 serpentine belt, you’ll notice problems in other parts as well.
“If the serpentine belt breaks, all accessories will stop working simultaneously,” -Curt Dupriez
The Function of a Serpentine Belt
In general, the function of the serpentine belt is to keep the engine running by transferring rotational energy from the crankshaft pulley to various components such as alternators, water pumps, and AC compressors among others. The type of pressure exerted by this belt depends on both frictional forces and tension level.
Besides driving these essential engine mechanisms, the serpentine belt also contributes to noise reduction, increased fuel efficiency, less vibration, and better overall performance.
The Routing of a Serpentine Belt
The routing of a serpentine belt determines how efficient each accessory system runs within an engine. Every vehicle has a specified OEM design for the path through which the belt loops around multiple devices. In an BMW X5 SUV, it wraps around ten separate points where they interact with 4 main pulleys namely; the water pump, the crankshaft, the idler, and the power steering pump.
When installing a new serpentine belt in a BMW X5, ensure you adhere to this format that was designed by experts for optimal engine function. A slight deviation from the routing instructions may lead to unnecessary wear or tear of the components connected via the belt causing expensive damage to your vehicle.
The Importance of Proper Tension on a Serpentine Belt
The proper tension on a serpentine belt has critical impact, not just on the life of the drive belt itself but all other components it connects. If the force is inconsistent, the pulleys or the belt can slip, and friction levels will also be reduced, impeding its efficiency significantly – leading to possible system malfunction.
To avoid these scenarios, you need an appropriate way of checking the tension of the serpentine belt before replacing it on your BMW X5. In the manual handbook, there are specific guidelines available based on make and model which offer step-by-step procedures to follow regardless of whether you have basic mechanical skills or not. Additionally, different car models require unique torque values; hence refer to specifications that match your car as well.
“If a belt looks loose, consult your user guide information rather than tightening it further yourself,” -Ross Kuhner
The Types of Serpentine Belts Used in BMW X5s
BMW X5’s come with 2 different types of serpentine belts depends on the production year. In early models such as those made between 1999 and 2006, the car had a V-belt design fitted with multiple individual belts driving each accessory separately. However, later models (2014 onwards) were installed with a single extra-long poly-ribbed belt making up a singular loop, that provides a more effective way of power transmission.
If you have an early model of BMW X5 SUV series and want to upgrade your car’s serpentine belt, it is possible to switch to the newer design type. However, keep in mind this process also changes how different systems are interconnected underneath the hood. Therefore we recommend consulting with a mechanic before making any upgrades or modifications.
