I think it's safe to say they give no real warning at all since what you read up by the T stat is not the temp around the chambers and if it boils there it'll decompose the FRP plastic cooling system components. It's a real injustice that Jaguar didn't give us a coolant temp gauge.

 

Don't think the x150 has warning lights fitted for low coolant,which is crazy in my book.It would have alerted me straight away to there being a problem.

 

I don't make it up but in the workshop manual for the 2010-2015 5.0L S/C it shows a coolant temperature sensor in the coolant pipe near the thermostat . I don't have the manual for the 4.2L so it may be different. It also states a warning light will come on in the lower center gauge cluster (in the area where the fuel gauge is) and it will trigger with low coolant and a high preset temperature that will protect the engine.

 

I saw in one of your posts you had a broken nipple in your expansion tank. Did you replace the tank and if you did was there a sensor on the bottom under the tank.

 

My electrical manual for 2010 to 2015 XK shows the SWITCH - BRAKE FLUID LEVEL is connected to the SW - COOLANT LEVEL input on the instrument cluster. Page 93 of 154 of the XB32573on.pdf electrical manual. I hope it is not right.

It appears that there are wires going into the bottom of my expansion tank.

So your model is s 2006? Not the 4.2 or the 5.0?

 

Yes mine is the 2006,so it must have been changed for the later models.Sorry if i misled anybody.
Thankyou all for your help.

I just screwed a nipple onto it. I don't remember seeing a switch in the bottom but there is a bundle of wiring going under it toward the module there.

 

Is it indeed an X150 built mid year or is it an X100? If an X100, you should have the moderator move this thread to the x100 forum. What are the last 10 digits of the VIN?

 

Sir,
You are in the right place!
What you are experiencing is an uniquely American phenomenon.
Nothing outside these shores is of any consequence.
Even though they own the very same car as you, they are unaware that it was released in 2006 in its Birthplace.

Back to the subject of overheating.

 

Yes I was aware, however, I thought both the x100 and x150 were produced in 2006 with the x100 ending mid year and the x150 starting mid year. That is incorrect. I was wrong. So back to the subject of overheating and providing actual help.

I can confirm there is no coolant level sensor noted in the 4.2 wiring diagram, however codes P011623, P011624, P011629 all indicate a failure in the ECT (Engine Coolant Temperature) sensor of which one cause is low coolant.

None of this is of consequence though given the immediate loss of coolant (given your description that water just pours out when trying to refill)

 

Sean, swear to god buddy I was not referring to you. Really speaking to the bamboozling and second-guessing that happens in our minds. When I first came here from England, I was ridiculed that its Aloo-me-num not Al-U-min-yum. So you think, jesus, I come from a village, this superpower, most advanced country in the world probably invented it and we pillocks have been saying it wrong all this time.

Only later in life you realize that someone from an actual village in England discovered and coined the term. And you are left with even more confusion.

 

P.s. note how he believed you guys and apologized for misleading you! LOL.

I was the same way. Now I know better.

 

Q&C, I saw that you quoted the OP, not me, yet my reply was a response to you directly. I have no idea why I did that.
I am truly confused by the actual dates these two models ceased and started, in both countries.

Wiki just provides year of production info and not the month and isn't at all clear on the builds in each country.

When I state that I'm wrong, I'm not trying to be defensive. I simply want others to ignore my previous comment and not act on it as that can cost someone money. (though not in this case)

That said, my wife will confirm I'm never wrong and I'm always defensive.

 

Mine was born on Jan 30 2007 according to Ford. The MY 2006 wiring diagram fits VIN's B09097 to B20074 so I suspect the British MY 2006's would have begun production around June of 2006 which makes them US 2007 models. With a B15694 VIN mine was literally born in the middle of the model year.

 

Then there are the 2006 x100's. Wiki show production of the x100 stopped in 2005. Was that in the UK where they proceeded to build the X150 and did Jaguar continue building x100 for the US market in 2006?

 

Apologies to the OP for hijacking the thread.

 

Wiki is Wiki, good and bad. It says the X150 design was locked in in 2002. The 2005 car show circuit ALC coupe is close but missing a ton of details so I don't think the design was 'locked in' even then. Per the transition from body types I think a month tops to reconfigure the build lines and get some training / test body's off. I'd suspect the sub contracts were started in late 2005 for parts and assy's.

I also suspect they'd run the '06 model year up until main assy's were all built. It would be interesting to start and thread in the X100 to see how late their VIN's birth dates ran. Same for the X150 to see how early they production cars were built.

FWIW, it doesn't look like many MY 2005's were built so maybe they pulled the plug early.

Just to confuse the issue, the UK registration plate has the year on it so cars tend to be referred to by that rather than model year e.g.

2006 JAGUAR XK8 CONVERTIBLE AUTOMATIC 4.2L, RARE COLLECTABLE
