Maintenance and Reliability
The 2UZ-FE is highly reliable but does require proper care:
-
Timing Belt – Replace every 90,000–100,000 miles. Failure won’t usually damage the engine due to its non-interference design, but it can leave you stranded.

Oil Changes – Regular oil changes with high-quality synthetic oil ensure longevity.
-
Cooling System – Maintain radiator and water pump health to prevent overheating.
-
Ignition Coils and Injectors – May require replacement after high mileage.
Common Issues
While robust, some common issues may arise:
-
Exhaust Manifold Cracks – Due to heat stress in high-mileage vehicles.
-
Oil Leaks – From valve cover gaskets and camshaft seals.
-
Fuel Economy – Averaging 12–16 mpg, it’s not the most fuel-efficient engine.
-
Heavier Block – Adds weight compared to aluminum 1UZ and 3UZ engines.
