Are you the 3.6 or the 4.4?

Get out, your not helping! 😛

Any wetness around the rad areas, The egr valves and coolers? Any oil heat exchangers? Gearbox oil heat exchanger?

OK, so nothing under the tank either👍

if it's the same unit👍

I It does yes and into a tube built into the casing. It goes to the right and down the tank side edge to underneath. 👍

Can you get your hand under the bottle and check for coolant from the drain that runs over and to the right?

Yes but.... Any signs of leaking? 🫣

Fair enough lad👍

Understood but if there are no traces of leaks then it ain't? 🤔😛

If it's just been driven there will be some pressure my mate. If it's cold there shouldn't be. The more modern systems are more efficient as these engines run even hotter for the emissions so they had to up the game for the cooling systems. 👍

Just be mindful of the extra forces on the drive train due to the programming 👍

I wouldn't worry about the sniff test unless it's caused a gasket failure 🤔

A good strong lamp and like kda says, start looking into the V or use a long cable or similar and poke about and look for residue, maybe pink or green crystals👍

How does it sound, does it roar or is it quiet on cold start up?

If no traces no leaks ? 🤔

How does the fan sound on cold start up?

That's definitely not something I'd like to even try 😜😂

Are there traces of antifreeze around the coolant tank?
