Ok, Range Rover sport 2.7 2007. I have had this 9 months and driven around 2k miles. The problem is that it looses water approx 1 litre every 100 miles. So far I have done a sniff test (all ok) the footwells are dry, replaced expansion tank, water pump and thermostat housing inc various pipes, still no difference. If I leave it ticking over there is never any water underneath. I am running the coolant system with water and it stays clean I'm thinking of replacing the rad but open to suggestions
Any help appreciated
Thanks

Likely weak spots are usually the cap or expansion tank. In general

Pressure test hot & cold as already suggested.

Had a few leaks over the years on my 3.5 Classic & it's usually been the pressure test that gave the 'Got you you bastard' moment.

Egr valve very common fault the lost coolant usually evaporates off so you don't know where its going.
Look up LRTIME egr valve
