How do you know when the supercharger is nearing the end of it's life? Do you get code or restricted performance light?

Has anyone had one go bad yet?

I'm not having any problems - just trying to figure out if the S/C is the "life of the engine" or do they typically need rebuild at some usual mileage figure.

Thanks,
Eric

 

Only replaced one for cracked vain. Other than that have swapped them from motor to motor and they still good. 100k +

 

Mine was making noises like there were marbles bouncing around inside. It was replaced under SE. Dealer said it was very rare.

 

i ve done a couple for noisy bearings.. chargers do need there oil changed.. on xj 98-2003 there was a fluid change interval and fluid in a tiny bottle.. cant remember for s type .. probably the same.. and it has a drain plug at the back of the charger.

 

Ooooh, that was a new tidbit of info; i.e. oil change.

I don't recall seeing an interval change listed in service/maintenance guide.

What interval do you recommend and what type of oil?

Many thanks!

Eric
