It's time to get the oil changed on my 2011 XKR Supercharger. Since it has to be removed I'd like to know if there is anything else that should be done while it is off the car like hoses, tensioners, pulleys, sensors or what ever. I know there was a post here that someone changed the oil without removing the supercharger but I don't think that's going to happen.

 

Number one job while the SC is off is to replace all the plastic coolant pipes/tubes.
And I mean ALL of them, after 10 years they will have become very brittle and one or more are due to crack or split.
It might seem like a big job but the parts can be bought for reasonable cost and 90% of the labour is in removing and refitting the SC anyway.

Number two job is to replace the SC torsion isolator/coupler, by now it either has already or will soon start to rattle.

Number three job is to replace the timing chains, guides and tensioners before one or more fail and cause catastrophic engine damage. This is a much more expensive job both parts and labour and may not be absolutely necessary just yet depending on mileage so your choice.

 

I had mine done last year by my local Indy.

Will dig out the price list with part numbers for you, but I went for:

1) All gaskets
2) All hoses
3) SC oil change (twice as much went back in mine)
4) SC belt
5) Coolant flush/refill (you loose 2l of the 13.8 in the system so makes sense)
6) Isolation coupler
7) Water pump if not done
8) Spark plugs (mine's only on 57k miles but thought best)
9) Smaller pulley is optional

PARTS added below with GBP prices

C2P13304 - coolant hose = £22.50
C2P16196 - Stock Hose = £49.10
JAJ811811590 - Gasket - £5.10
JC2D39175 - SC Belt - £32.53
JAJ811576 - Gasket - £44.09
JC2D58056 - SC Kit nose inc coupler - £362.82

Total £516.14+UK VAT at 20% = £620 inc ($820 at today's tourist rate)
Note that I get 15% off parts at my main dealer.

The SC oil can be sourced from Powerhouse in the UK, but it's the labour involved that is costly, so

5hrs to remove refit SC
1hr to remove replace spark plugs (well documented that 3 are a complete PITA even for a trained person, it took Indy 2 but they charged me 1)
1 hour for coolant flush/change (to Evan's waterless)
30 mins for water pump

My Indy charges £65ph plus VAT ($101 USD) so there was a labour bill of £585/$790 on top

 

This seems like a totally separate job. Not sure why it would be suggested in this case...
