Tarka is laid up at Williams, waiting for a diagnosis of the horrible squealing noise coming from the front of the engine.
The noise, which sounds very much like the "serpentine" auxiliary drive belt or something driven by it isn't exactly new, for some time would come on very occasionally for a few seconds when the engine was cold, but soon disappear
Driving rather quickly at Castle Combe the noise became constant and louder....although once the engine was cool it was quieter but still very noticeable.
Has anyone else had this sort of experience with the belt or parts driven by it?
As everything works and there are no leaks, no warning lights, the view from the Williams Technicians was that it is, in order of probability..
1. The belt,
2. A belt idler or tensioner pulley.. there are 2 idlers and one tensioner....
3. The water pump, A/C compressor or alternator.
To make a diagnosis the bonnet and cowl have to come off.
Replacement of the faulty parts may well require one or both wings off.
The track day may well turn out to be expensive.
