Default Buying an XK with a replacement motor good or bad?

Ok, I'm planning on buying my first Jag on and I found out the motor was replaced by the dealer in 2015. The previous motor overheated due to a coolant issue at 48k miles. The car has 60k miles as of now. All maintenance performed by dealer under warranty. Was there any updates or changes to the motor from 2011 to 2015? And is this I good buy or should I look for something else?
Thanks all!

I should add the car is a 2011 XK 5.0 naturally aspirated with a 2015 replacement OEM motor.

I can't think of any reason to avoid this car. Water pumps can be leaky on the 5.0 which I suspect may have been the genesis of this issue?

Correct. The car fax shows the water pump as well as thermostat housing was replaced the same time the motor was swapped out.

My only concern about engine swaps is everything has been taken apart and put back together again. Sometimes this creates issues down the road for the next guy. Certainly not a game changer but something to keep in mind as well.

I guess a more relevant question is what's your intended use and duty along with how long do you plan on keeping it?

Did Jaguar correct the water pump issue before 2015 or are they still faulty by design?

I plan on casual driving and keeping it for quite some time. I go easy on my cars and spoil them with maintenance

I'm picking the car up for $21k so I feel like it's a great deal with a basically new motor.

yea that's a pretty good price. Is there a warranty on the new motor? If so, don't worry about the water pump. Not sure if the 2015s had the newest water pump in them but I'm pretty sure I read somewhere that they did.....

Can you test drive another XK similar year (2010-2014)? I ask because I witnessed what Ranchero is describing. I drove a 2010 with a Jag dealer executed engine replacement (same issue, overheated) and it just didn't feel right. There was lag on acceleration and it seemed sluggish. I then drove the one I ended up buying and there was a huge difference.

Not to say you will witness this but if you can, go drive another one just for grins.

The car was traded in 12,000 miles after the motor was swapped out, it then went to auction so there is no warranty I'm aware of on the motor. I did however call the dealership that performed the work and they confirmed the motor was replaced at 48k.
I'll look and see if I can find another I can test drive. Good suggestion...

Seeing that makes me feel good about the deal I'm getting. lol
Question: Does the 2011 XK Not have a tempature gauge of any kind?
It would seem that you would want to really monitor the temperature of this car with the design flaws it has.

no coolant temp gauge in any X150. We complain about this weekly

You can add one using the OBDII port if you want but there are not many good places to mount it.

That seems risky considering the issues this motor has.

I'm sure there's at least a dummy light when you start to overheat correct?

The dummy indicator comes on when you are pretty much done overheating - something like 245 F. Not very much warning anyway.

With the 2010-2015 series cars you get 3 warnings. The 1st is a low coolant warning because the coolant tank is low. The second it temperature overheat which requires immediate shut down. The 3rd is white smoke coming out of the front of the car. If you pay attention to 1 and 2 then the engine should be OK but if you reach 3 all bets are off.

Looks like I'll be getting the Autool x50!
So nobody knows if the replacement parts being put on are better than the flawed OEM parts?
