Looking at an XF 3.0 with a failed / noisy supercharger, can it be driven with the supercharger belt removed?

It needs to come home for diagnosis rather than go for a very expensive trailer option.
Regards all,
Rich.

 

Quick answer would be I don’t think so, depends if it is a dedicated belt or a serpentine driving all other ancillaries.
On my ‘99 XJR it is only one belt.

 

Greetings Rich but . . . 3.0L supercharged XF ??? May I suggest you need to post your question in the relevant XF forum where those with expertise on your model can better address your question. As the title notes for this forum says, this is for general, not model specific, technical issues.

Best wishes with your supercharged XF . . . or, as I suspect, turbocharged XF.

Diesel = turbo charged Petrol=Supercharged.

 

I well know that, having driven the magnificent predecessor TTD S-Type for years, but I need to emphasize the critical point you missed in replying to the OP's question . . . he does NOT have a belt driven supercharger . . . he has a NON belt driven turbocharger (actually a pair of them).

If I sound pedantic, it is because the missing belt is undoubtedly the serpentine, which if he drives, or even runs the engine without it in place, will . . . in short order and without warning . . . result in an overheating event which could easily end in catastrophic engine failure.

So, Rich, do not drive or even start engine until belt is replaced. In the meantime, I suggest you do some fast reading to learn all you can about the 3.0L TTD engine (and/or the 2.7L TTD which preceded it). Personally, and with plenty of experience to back me, I love these brilliant high speed Jaguar V6 diesels, but there is no way I would purchase one with failed turbochargers and missing serpentine belt. What other problems are hidden deeper?

Just my 2c and best wishes.

Sorry Ken are you reading the same post as I am? Fairly sure this says supercharger?

 

Yes, I am reading that . . . and I realize your XJR is supercharged . . . but what I'm trying to advise both you and Rich is that Jaguar produced no such animal as a "3.0L supercharged engine" in the XF or any other model that I know of, whether petrol or diesel powered.

However, what Jaguar did produce and I suspect Rich is investigating prior to possible purchase is a 3.0L Twin Turbo Diesel V6 . . . derived from the earlier 2.7L TTD V6. Again, I offer this warning . . . if, as I suspect, the missing belt is for no such non-existent supercharger, but is, in fact, the main serpentine belt, the engine should not be run with thus, no drive to water pump etc. Overheating will be an inevitable consequence . . .

Anyway, any further conjecture will be readily resolved if Rich investigates further by identifying the car's full 16 alpha-numeric VIN #.

Ken am I reading this incorrectly?

 

No, you ARE correct if referring to the now current model XF (X260) as produced in the last 12 months, whereby a 3.0L supercharged petrol engine IS now available.

But if, for a second hand XF of the far more likely generation for the 9 years from 2007 to 2016 (X250), the only supercharged engine was the gorgeous 5.0L big brutha. Given that Rich is investigating a second hand XF which the seller is parting with in an unrepaired condition, I not unreasonably deduce it is the older X250 . . . ie no supersharged 3.0L engine.

In either case, the car should not be driven . . .

Cheers,

Ken

 

Rich, are you going to leave us in suspension regarding what you have decided to do about the car?
