2016 X351 Water lines

Have had several water lines changed on our 2016 XJL V6 supercharged,
The latest proplem area being the thermostat, and I am told here is 1 more line to be done.
Just a heads up to others to lookout for. Am dropping it off at the dealers this week.
So much for plastic parts.

I completely agree. I know why the manufacturers make all this stuff out of plastic, but don’t agree with it. Seems like every car is built this way nowadays.
