Known problems on the Toyota Prado 120

Head gasket leaking coolant

What to look for: Check the coolant bottle level, then watch for white sweet-smelling smoke, misfire or a rising temperature gauge.

Water pump leaking coolant

Costly if missed

2003–2023 · 1GR-FE · petrol · Engine

What to look for: Look with a torch at the front of the engine around the water pump for pink crust, wet streaks or drips.

Why it matters: A leaking pump gets worse; running the engine low on coolant can overheat it and blow a head gasket.

Typical repair: NZ$700–NZ$1,500 in New Zealand · A$720–A$1,550 in Australia
