The drive belt of the Land Rover is an essential part in the efficiency of its engine. Some of its role includes driving multiple peripheral devices in the engine such as the water pump, the alternator, and the steering pump. The most important job of an accessory drive belt in a Land Rover is to create less friction in the engine, which gives the car overall better performance. A defective drive belt may be caused by the friction and heat that accumulates on the belt, causing it to deteriorate and snap.
In most cases, you need to replace the drive belt, also known as the serpentine belt, in your Land Rover about every three to five years or 45000 to 75000 miles. However, since the belt is made from a very durable material, it can last for as much as 100000 miles, although this does not stop it from wearing down over time. Noises of squeaking and chirping may be heard from the engine bay if the drive belt wears out. If the belt suddenly breaks, the vehicle will experience some overheating and eventually break down. It is important to keep an eye on the status of your drive belt so you can prevent this from occurring — after all, no one wants to be stuck on the side of the road!
Land Rover Drive Belt Function and Purpose
The Land Rover drive belt drives a network of parts that work together, so if something happens to the drive belt, all of those parts, from the air conditioning to the alternator, may suddenly stop working.
The drive belt is also responsible for delivering adequate power to the other components of the vehicle. Land Rovers tend to be large cars, so they require lots of power to run optimally. If the drive belt begins slipping, that power may not be generated and allocated properly, leading to low engine power, lack of air conditioning, and even eventually the car stalling out.
Reasons for Drive Belt Failure
Drive belt failure can be due to any number of issues, including some simple manufacturing problems in specific models. Driving habits and conditions such as frequent short-distance drives can also cause the drive belt to deteriorate quickly due to the strain caused over time.
Harsh and ever-changing temperatures may lead to expansion and contraction of the material, thus making it susceptible to crack and tear. Of course, general wear and tear will lead most drive belts to needing to be replaced eventually.
Symptoms of Drive Belt Failure
The components of the Land Rover that are powered by the accessory drive belt also dominate the power delegated to the engine cooling system. If the engine is unable to cool itself properly, it will overheat, leaving the internal engine components damaged and the driver of the car stranded on the roadside. If the car overheats badly enough, some engine components can become damaged enough to need replacing, turning one small repair into a lot of larger ones.
During the winter it can be difficult to tell if the smoking from the exhaust is bad or not, but if you note an unusual smoke from the tailpipe, then the problem may be the drive belt. Another symptom of a bad drive belt is when the timing belt is cut off completely. In this case, the crankshaft will turn itself on, and it will not be in sync with the rotation of the camshaft. This could damage the valves and the piston. A new drive belt should be installed once this symptom is noticed to prevent damage further to the engine.
