I know that chasing fluid leaks on an old Defender can be a fools errand but it's worth a shot.
This is a right-hand drive 300 tdi 1996 Defender 90.
I replaced the intercooler about two years back and put in new coolant. I checked recently and the coolant was low... bit of a puddle on the Turbo side (right side) kind of under the heater. Topped up the expansion tank again with Valoline Zerex G05 (greenish color).
The "drip" ends up falling from where the Engine touches the clutch/gearbox thing (sorry, have not got into that part of Defender maintenance yet thankfully).
It looks a bit wet under the turbo and the starter motor. Top of the top of the starter motor is dry, same for the coolant lines on front and back of the valve cover area. No leaks around the heater box that I can see.
The fluid looks green (windshield washer was a mix of red for winter and blue for summer).
I have got most of the Yorkshire mud off but as you can see there is still some around where the fluid may be coming from.
It's odd because there does not seem to be a coolant line near that side of the engine that would be leaking?
There is a little weeping around the p-gasket but I can see where that falls and it's to the front of the truck.
I don't have a pressure tester and I don't feel like tasting it to see if it's actually coolant.
Looks a bit down here in this picture but this is after a few days of scrubbing and cleaning (could be mixed with dirt now)
