Hi guys looking for advice please . at what age or millage , Do the ancillary belts on my car need changed out ? my car will be 9 years old in January and is currently on 60k miles . Thanks

 

Here's the Jaguar recommendation:



Odd that belt changes are only MILEAGE based in this 2010 document. The current equivalent document 2019 document gives:

every 7 YEARS or 105K MILES for the supercharger belt
every 10 YEARS or 150K MILES for the accessory belt

Thank you Graham . it was my understanding that a fuel pump belt or an oil pump belt also needed changed also ?

 

George, on the accessory belt, they dont give way like the belts of before, there is ample warning.
I would replace only if you saw cracks and it was making noise.

I have regretted replacing serpentine belts on other cars unnecessarily as I have never found one as good of quality as oem belt.
Where the original has lasted a decade, I found myself replacing the aftermarket ones every 3 years.

 

Thanks Q&C visual inspection the belts look good . but will change them next year a year early just to be on the safe side

 

NO - oil pump is driven by an auxilliary chain and the submersible electric fuel pump is mounted directly on the tank.

Many thanks again Graham . Great info and advice on here

 

I thought he referred to the HIGH pressure pumps. Me, I have No Idea how those are driven, other by engine rotation.

 

George you've probably charged people to change their wiper arm belt- metaphorically speaking, and now the rooters are coming home.

High pressure pumps are driven by timing chain.
