I drive an XF 2010 and my car has a red sensor light that reads Coolant low. I brought to the dealership to get a fluid top off; they said that I needed to replace to coolant resevoir. Skeptical I asked if I can just replace the sensor but they said the sensor is built into the coolant.
1. Is the sensor really built into the coolant?
2. Does anyone have any DIY instructions and pics on how I can replace the coolant?
The reservoir is pretty cheap. They fail, crack and leak when they get old. The sensor is not user serviceable easily - a few people have done it but it was more work that it's worth. You can diy the reservoir yourself in no time or a quick job at the dealer.
These plastic components that constantly heat cycle don't last forever
Search on the X250 forum which is the right one for your XF model and you'll see quite a few posts about this

Is x250 the same thing as XF model? You’re saying it’s not worth it doing it yourself?
When they redesigned the XF, the XF name stayed the same, and it doesn't look that much different, but its a very different car underneath. The X260 is the designation for the new car, which started with the 2016 model year. XF's before that have the X250 designation. So there's a separate forum section for X256 vs X260. Since those X designations are not widely know, it would be a lot more obvious for everyone if the forum name just listed the model years instead of the X designation.

so I should search for x250 when I search for items relevant to my xf 2010 on this site?
Perhaps a moderator can move this thread over to the X250 section. (Btw - look in 'modern' jaguar folder and you'll find it there)
Lots of active posting from people with the 2009-2015 model which yours fits into
On the reservoir question, you can absolutely do it yourself. It's an easy replacement. It's cheap so I'd suggest you get the whole reservoir not just the sensor - not worth messing with the unit
Then fill with the right coolant, and keep an eye on it to ensure it's not leaking anywhere
Also you can download the service manual (search the X250 section and several threads on where to get it). That makes these sort of diy jobs v easy - lots of pictures of what to do

Welcome to the forum PJ704,
I've moved your question from X260 to X250 forum. This is the place to post technical questions about your model.
Low Coolant Warning Sensors are definitely replaceable on the Supercharged model although I cannot find one listed for the Normally Aspirated which has a different Expansion Tank. The Sensor clips into the bottom of the Expansion Tank and has a nearby harness connector. However, it requires removal of the Expansion Tank to fit a replacement sensor. Here is the relevant page from JEPC (Jaguar Electronic Parts Catalogue) for the S/C (see item 3).

Replacing the tank looks simple enough but how would I disconnect the two hoses that connects to the tank without having fluid spill out all over the inside of my car?
before you go replacing parts, check the water and anti freeze mixture.
I had this happen on my 2009 just this week, I thought hey maybe its low so I added water. That didn't help,
We later looked inside and saw the float at the bottom. We used a long screw driver to help it up and the warning went away.
We then checked the coolant mixture now I'm sure the ratio wasn't as bad until I added the water but it was only good for -12 degrees Celsius.
We ending up taking a lot of the water and coolant out and then added concentrated coolant. I got the rating for it up to - 37 degrees.
Closed up the hood gave the car a start and it was fine.
this only cost me $20 bucks Canadian.
The reason why changing the reservoir works is probably because they have to put in new coolant.
hope this works for you, some people may say coolant is anti freeze.
side note, when buying the coolant buy any brand, long life coolant it will mix in well.
Good luck!
He y Maninder thanks for your reply.
Attached is a pic inside my tank. You can see that the fluid level is up to the max line. The fluid was refilled by Jaguar so I'm assuming they didn't use a 50/50 mix. Is the black circle the float you said that is stuck? If so, its at the bottom of my tank. I used a long screw driver to poke at it but didn't want to use force fearing that I might break something.

yes it's that white thing under the black circle. It's a cylinder that floats some cases it might jam up because of grim bit its supposed to rise up. I'm out right now I'll get back and get back to you on a laptop

Thanks for the quick reply. Am I supposed to pull that black circle back up? Do you have a pic of how it looks when it is working correctly?
