Hi, I’ve had some coolant and water dripping from what looks like an overflow drain from the aircon? Located passengers side. Drips down and onto the transmission sump then then ground. Any idea how the coolant managed to leak in? I’ve recently changed the water pump and both hoses. I’ve attached a photo, cheers!

I'd say you have a leaking heater core. It's reasonably common.

As Losh said, leaking heater core is the only way coolant can leak from the A/C drain hose.

Not sure with VT but some earlier models you can replace the core without removing the dash.

VT & VX is a DASH out job ! :mad:

The Common cause of the heater core leaking, is cooling system corroded,
and when you do a good flush of the system, the gunk in the heater core is flushed out, and the cooling system works more efficiently and can build up pressure, and will leak at its next weakest point,
or some people twist the hoses off the heater core under the bonnet, to flush the heater core out, and that can damaged the pipe solder joints on the Core
I am still loosing coolant, and its not dripping it, so its consuming it, so I am now thinking its the LIM Gaskets,
I figure, If I am going that far to do those, I am going to do Head Gaskets.
I replaced the Gasket between Supercharger & LIM when I replaced the Bearings, and serviced the Supercharger, a little while back as the SC snout bearing was a bit noisy, so I removed that and pull it down and servicing that.
That's when I had a few more leaks at the next weakest point, one being the Heater Tap, it become brittle over the years, and was leaking on one of the outlets,
I then replaced the Heater Tap, and ALL the hoses [Radiator & Heater]
I removed the old Heater Hoses at the Heater Core by slicing them, and then splitting them open to remove them,
then sliding the new ones on with Gasket Cement,
Done that a few times with our VT & VX some time ago, and more recently with our current VY.

Pray for you that the heater core isnt the problem. If so then you need to decide whether you remove the dash or scarp the entire car.

Leaking core isn't necessarily the end of the car or an urgent repair. They can go for years like mine is, weeping away and only losing 150mls every three months. When it gets real bad things can get a bit smelly. It's at that point you decide your three options, bypass the core, repair or sell.
Fortunately for me it's a 1hr job in my ute. Only downside is a heater core is around $170 and in Tas in the winter you have to have a working heater.
