Coolant expansion tank bleed lines
Hello all, something I noticed on my '02 XK8 while getting to my heater pump: on the top of the expansion tank there are two bleed lines, one goes to the thermostat housing and the other goes to the top LH side of the radiator in the back. When I removed the lines from the expansion tank the nipple for the back of the radiator line was plugged! Yet there is a line installed going to the back of the radiator. Any idea of what's going on with this? It's just a solid nipple.
Thanks as always.

This presents an opportunity for overheating on 1997 cars. If the coolant reservoir is replaced with the 1998 onwards version and the hoses are connected as they were originally, the airflow between the coolant tower and the reservoir will be curtailed.

I'm afraid I can't answer you question on statistics, and it would make more sense to me had Jaguar specified that the frontmost port on the superseded CET should be the blanked one - no plumbing changes necessary then.
It's likely the supersession considerations took some account of the radiator bleed deletion: another 5 minutes thought would have scored 100%.
IMO plugging the radiator outlet would have been better, given how fragile the bleed hoses become after years baking on the top of the motor.
