t4 cooling system

[ericcs]

Is this an additional external water pump on a my son's 2.5l petrol T4?
As you can see, the neck has snapped off, resulting in a dead engine.
there was no indication from the temp gauge, guess it can't read water temp
if there's no water to measure. Car died soon after losing power.
Mechanic measured 40psi on a couple of cylinders, but i'm sure it's more than
a blown head gasket, considering it dropped all the water in net to no time!

Geeze, that's a shocker.
I had a similar problem with a Nissan many years ago when a dodgy hose clamp to the heater popped off.
Cooked the motor but it was under warranty..........no indication on the temp gauge because it had no water in it!
They wanted to argue about it a bit but they were the only ones who ever touched it and they came to the party eventually.
I'm pretty sure they only put a new head gasket and levelled the head though.
