Did they replace the coolant pump?

Hi Everyone.
We just took delivery of a new P300 Down Under about a month ago (retired the 15 year old XJ Sport to the garage for our kids) and you guessed it - a week later the car sounded like it was going to launch itself into space. The roaring fan noise was so loud people just turned and stared as you drove up the road.
Our very helpful Jag dealer came by the next day, dropped off a loaner and took the P300 back to the dealership.
Came back 2 days later all shiny and fixed but it has started up again today doing the same thing, mild day and only drove for 3 minutes so sounds like an ongoing issue with this model.
The dealer is very helpful but doesn't earn brownie points by making out as though he's never heard of the problem before. Don't you just love it when they pretend you're the only one on the planet with the same prob?
Anyway - sounds like this has been an issue for a while elsewhere so any new ideas on the cause?

Well it's the coolant pump for sure which sends signals to fan to run at full speed and non stop till the point you switch engine off.
If dealer is unaware then your best bet is call jaguar assistance play dumb like oh my God car is making very loud noise from engine bay I don't feel comfortable and so on... They will come out to you make a small report most probably would tell you it's the coolant pump and you get your diagnosis done. Then get it replaced under warranty.

Thanks.

Regards,
KJ

Thanks for that KJ!
Dealer is coming by this afternoon with loaner car and picking ours up for fan replacement.
Sounds like there must be a design/manufacturing fault with these ones so I guess sooner or later there will be a part modification and it will all go away.
Just a lot of trouble for everyone with one of these models.

Hi All,
I had my water pump replaced in July last year, it was successful in stopping the fan from running at full speed, now I have noticed since the colder weather I normally have the air con turned off, but when I do the fan runs constantly at what I would say is quarter to half speed no mater what the temp outside or the engine is, however when I push the heater Auto button on the dash, and both orange lights are on, the fan stops, and then runs as normal, not running when heating up the engine, and then turning slowly now and again when warm, and the gauge never goes above normal.

has anyone else noticed this anomaly ?
William.

Hi,
Well people over here earlier got fan replacement done which was of no avail.
You can ask dealer to please check fault codes which would point to faulty coolant pump.

Thanks.

KJ
