Hi All,
I have had my 2015 v6s since 2019. Bought on 17k miles, now on 38k miles and always garaged. I was worried about the y pipes. Booked into an Indy Jag specialist (EMS Jaguar) to get checked over and pro actively replace;
Y pipes + all associated coolant pipes, thermostat, supercharger coupler and water pump as required. I also asked for all cam cover bolts to be replaced as a precaution. Also had the supercharger oil changed. Water pump had minimal wear, but asked for it to be changed. Supercharger coupler was perfect, so that was left alone.
EMS would only use genuine parts and advised that they would only use the genuine Jaguar supercharger coupler if it needed replacing. Luckily it did not.
The cam cover bolts were rusted away to virtually nothing and one of the bolts holding the supercharger in place was severely rusted. It was a £2k bill, but with hindsight it was the correct decision. First “non regular maintenance” bill, but hopefully it will be good for another 10 years. After seeing the state of the bolts, I would consider this essential maintenance at 10 years on a v6 / v8 RWD car.
