Question about 1999 Jaguar XK8

Identifying and Replacing Serpentine Belt

I was driving my car and went in my house to grab something real quick. When I came back out, the screen where the mileage is reported was scrolling unfamiliar text. It was saying "engine running in fail-safe mode", "VSC off" , "ASC off" , and other various bad things. Also, the GPS screen was flasihng on and off when I was stopped at stop lights amnd sometimes while driving. I managaed to make it back home quickly and park without the use of my power steering before the car completely died. After talking with my dad, he suggests that the serpentine belt needs to be replaced. Anyone have any other suggestions on what the porblem might be and how I can fix it without getting my car towed?

Nope, it does sound like the serpentine belt broke.
All you need is a long 15mm wrench to replace it.
The belt from Jaguar is about $90.
It takes about 5 minutes to replace the belt.

My first impression would be the serpentine belt is worn ...specifically it has "glazed" and stretched so it no longer has the ability to effectively grip the drive pulleys it spins. Typically when the serpentine belt loses "traction" it will squeal as it slips on the metal pulleys of the accessories it is designed to operate. There also may be a problem with the the tensioner ...a device used to keep proper tension on the serpentine belt. This is an easy and relatively inexpensive repair ...probably cost between $100 and $200 ...depending on whether the tensioner needs replacing.
You really need to get this fixed. If the serpentine belt fails breaks or comes apart will lose power steering and the water pump as the two critical accessories the belt operates. Obviously the loss of power steering can make the car difficult to drive and the loss of the water pump will cause an engine overheat condition fairly quickly. The A/C and alternator will also drop off line but these aren't as critical as the steering and water pump.

sounds like your alternator is seizing up. take of the serpentine belt and turn the alternator by hand if it sweels or don`t turn, time to replace it. easy fix if thats the case. while your belt is off check the other pullys as well.

Power steering went out air conditioner went out and engine started racing on and off while driving all happened at the same time

You just broke the serpentine belt, no big deal, you can drive it to a parts store, just keep it moving or it will over heat and it will drain the battery, so you have to be quick. get a new belt on there, you should be all set. Hope this helps.

When to change Timing Belt.

I am pretty sure you are asking about the serpentine belt.The timing belt is inside the engine and should not need replacing unless the engine is running REAL bad.If you are talking about the serpentine belt,a rubber belt which the engine drives and it powers the alternator,a/c,power steer,power brakes.There may be a mileage requirement for changing,but it is more about inspecting it and deciding.If there are many small cracks,or a few big cracks,or some fraying around the edges,then it needs replacing.Or if it's stretched a little too.A sign of that would be slow overheat,a/c may seem a little less cold than normal.First you need to make a diagram of how the belt is routed.To change it,you have to pull the tensioner away from the belt side to loosen the belt,then slip the belt out of the grooves and off.The tensioner is round and looks like it isn't connect to anything but a wall or have a purpose but it is spring loaded.When you put the belt back on,start from the engine,pulling up slightly so it doesn't fall off,and work both sides until you're back at the tensioner.Push the tensioner away from the belt wrapped side and slip it over the edge.
Good luck! Greg

Torn Serpentine Belt. Bad belt driver

You say belt driver? The belt runs on a series of pullys, there should be a pic./diagram on the radiator support that shows the routing of the belt. simply take the belt off and check each pully( they will either drive the belt or be idlers/tension pullys)to see which one has any "side to side" motion. If it is on a "driver" you are looking at replacing that part(water pump,power steering pump. etc.), as the real problem will be a bad bearing in that unit.

Serpentine belt replacement

2.0L Engines
See Figures 11, 12 and 13
The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced.

Power steering pump

your serpentine drive belt could be slipping over your power steering pump. Sounds like a premature failure from your pump. This is not an easy fix depending on the location of the pump itself. Remove your serpentine belt, locate the pump and pulley. Try to spin the pulley by hand. If there is alot of tension, your pump may need replacing. If not, try replacing the belt and check your belt tensioner for looseness.
