Hi Everyone

I have been recommissioning my 2.0 lancia beta spyder and have a coolant leak. As soon as I add water to the coolant tank it drips out from under the yellow timing belt cover.

The leak occurs without starting the engine and leaves the coolant tank completely empty.

Just wondering if anyone has encountered this before and had any thoughts as to where the leak could be coming from.

Many thanks in advance

Hello Si, and welcome,
My thoughts are the water pump assuming your leak is towards the rear area
of the cover.
Take the yellow cover off and you'll see it. There's good access to the pump
from under the wheel arch area.

The only other possibility is where the top steel coolant pipe mounts to the head,
but you'd see that from the top.

Best wishes,

oh,and an Uno Turbo 1997 also in SA [stolen,never recovered]

Agree water pump if the leak empties the tank. This happened to me when I fitted a new pump and got a very slight fold in the paper gasket.
