2006 Jaguar Sovereign engine liquid overheating .

So why couldn't they repair it?Also you have oil in the coolant?

they could not repair it because they are not so qualified for that, even they
the jaguar dealer in Morocco, they are not honest dealers.

What did they do to it to fix it the first time?Also is there oil in the coolant?

they said problem in the radiator it mixes oil with water, they said that they changed it, and the car is ok now, but it was a lies .

Does the radiator look new?

it looks new , even the car is new it has now 25000 km I never enjoyed it!!

Are you sure they just didnt flush all the old oil out of the coolant?

They empty it and put new coolant. It eas ok for some days then the problem came again

If they only drained and refilled the coolant there's one problem they should have flushed it all out.So is it oil or transmission fluid?

they said transmission fluid, they have flushed it and refilled with clean coolant, I used it for some days was every thing ok , but the problem uncured again ( overheating , the coolant was going out very hot from the engine mixed with liquid like mayonnaise, ) now the engine starts normal
no any indication of up-normality only after some minutes the mayonnaise
starts to come out again.

If its transmission fluid then I would say its for sure the transmission cooler on the radiator leaking into coolant.I cant tell you what went wrong seeing the new one fail so quickly would be pretty unlikely it is possible though.Iam sure if jag has a problem with those I know jags overal do have a lot issues.So you are the radiator was actually changed?Because if it wasnt that would explain alot.

how we repair it , do I change the radiator again and check if it is o k, now
I remember, when they told me (we changed the radiator) , I asked them to giveme the old one , they refused , so I doubt they have changed it , what do you think
thanks.

That's really crazy they wouldn't give you the old one or atleast show you it.So what did they say when you returned with the same issue they just fixed?

once the guarantee period finished , they told me to change the engine
on my cost, here strange things happens, you know what they were planning to do, they want me to buy new engine , and they take my engine to
sell it to somebody else, because usually clients do not take the old parts of
a repaired car, but because I am an aircraft engineer, and I know this kind
of job, they could not cheat me, if you talk to these people working in Jaguar
Maroc and you smile to them you have to count your teeth afterwards , best regards
