Welcome to the forum Azartist,

I've moved your question from General Tech Help to X350 forum. This is the place to post technical questions about your model.

I expected there would have been some replies before now. My thoughts to get the discussion going.

1. the squeal suggests either the drive belt or an accessory issue.
2. the battery light coming on suggests the alternator was no longer rotating.
3. temperature rising suggests water pump no longer rotating.
3. an empty PS reservoir/loss of power steering suggests a broken pipe or steering rack seal.

You did exactly the right thing to stop and have the vehicle towed. Overheating a Jaguar V8 is an engine killer.

The simplest explanation is the Drive Belt (often called the 'serpentine' belt) has broken:



As can be seen from the diagram, it drives the Water Pump, Power Steering Pump, AC Compressor and Alternator (generator). Once the belt stops turning, so do all these accessories.

A second possibility is the Tensioner (item 2) has seized. This is a spring loaded pulley which keeps the drive belt under tension. It is a known failure on the V8 engine.

The loss of PS fluid raises a third possibility - power steering pump failed.

Your prompt action has almost certainly avoided catastrophic engine damage but, if you are not able to DIY repairs, the cost could still be an unpleasant surprise if it turns out to be the power steering compressor.

Yes, they can be expensive sometimes. Still doesn't explain the loss of PS fluid, thiugh.

 

 

 

 

Any reason for not having any PS fluid in the reservoir ?

BTW, glad to hear you're "up and running" as the IT industry guys would say !
