Coolant leak - pretty sure is the water pump connector
14 ftype s 75k miles
Driving home today I got a low coolant message. When I got home, coolant steam was coming from the drivers side front.
gonna be bringing her in tomorrow, but wanted to see what else I should get replaced/maintained while I have this opportunity. Thanks!

From the driver's side front (I assume LHD so LHS) it could very well be one or both of the small pipes/tubes of the expansion tank pipe which runs from the expansion tank across the front/top of the engine to the LHS (but only a little left of centre) of the front crossover coolant pipe.
I also have a 14 S (V6 not V8) and so far this has been the only coolant tube failure on my car, those little tubes go very brittle with age and eventually crack/split, mine were like uncooked spaghetti before I replaced this part.
Open the hood, top up the system with distilled water, then start the engine and see if you can spot a/the coolant leak. If it is one of those little tubes then a gentle wiggle will quickly reveal the leak.
But plenty of other places it could be leaking from, most commonly that front crossover pipe which is prone to split along the seam.
If it is one of the main coolant pipes (there are at least three) then the SC has to come off to replace it so it would be best to replace all of them at the same time while the SC is off, as removing and refitting the SC is a labour intensive job and is the major cost in renewing those pipes and you don't want to have to pay to get it done a second or third time.

I had one go at 12,000 miles on a 2010 XKR - the seal just started weeping so I had it changed for safety.

Coolant pipes were a bad design and were re engineered with more durable plastic but not sure when. Had a 13 XF that I had to replace them on. Not sure if the 14 motors had the new design or if it was still the old style. Mine cracked at the crossover pipe at the seam and also at both points where they entered the block under the supercharger. Required removal of supercharger to replace the pipe. Jag will hit you between 2000 and 3000K if they do it even though they acknowledged that it was a bad design and designed made new parts, such great customer service.
