What you are looking at

No photograph available

We do not hold a verified photograph of the Water pump or Turbocharger yet. We would rather show none than show a picture of a different part.

What goes wrong

The Stelvio's 2.0 turbo shares the Giulia's cooling weak points: water pump housing/gasket leaks (reported from about 70,000-100,000 km), brittle plastic bleeder screws that can snap and dump coolant, radiator end-tank leaks, and the turbo coolant feed pipe collar (an owner-documented failure around 119,000 km). The engine requires the specific purple OAT coolant; the water pump job is labour-heavy on this engine.

What you would notice

Recurring low coolant warning
Coolant smell or steam after hard driving
Dried purple/pink residue on the front of the engine
Overheating in traffic

How to check it

Where to look. Front of engine - water pump, thermostat, coolant hose bleeder screws, turbo coolant feed pipe

Check coolant level and colour cold, inspect around the water pump and hose bleeder screws for crusty residue, and look under the car after the test drive.
Ask specifically whether the water pump or any coolant pipes have been replaced and see the invoice.

Parts involved: Water pump, Turbocharger.

What it costs to put right

$300 to $2,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the water pump been replaced yet?”
“Has the car ever lost coolant or overheated?”
