Got used LR2 ; Coolant Leak detected next day :S

[Fadz]

HI fellows,

 

I am just new to Landrovers, so please excuse if I ask some stupid questions. But what happened the very next day of purchasing a Land rover LR2 is it starts showing Coolant Level Low, I take it up to Musaffah and the mechanic said they need to do some pressure testing for coolant and other parts. 

 

Is that normal? Feeling annoyed, depressed.
