Hello i have a jaguar which cranks so much to turn on and then it gives me engine overheating while the engine is still cold what does this mean

 

Sorry but can you give more details?
Have you checked for codes?
How many miles?
Where are you at? I ask because we get questions all the time for Diesels and we never got those engines so we have no experience with them.

I had a Ford explorer that had similar issue but with - temp coming from the sensor. Caused similar issues, check with scanner.
