EG-141 ENGINE – TURBOCHARGER SYSTEM (2JZ–GTE) PRECAUTION 1. Do not stop the engine immediately after pulling a trailer or after high speed or uphill driving. Idle the engine for 20–120 seconds, depending on how hard the vehicle has been driven. 2. Avoid sudden acceleration or racing immediately after starting a cold engine. 3. Do not run the engine with air cleaner removed, as this may cause foreign material to enter and damage the impeller wheel operating at high speed. 4. If a turbocharger is found to be defective and must be replaced, check for the cause, and repair or replace the following items as necessary: • Engine oil level and quality • Conditions under which the turbocharger was used • Oil lines leading to the turbocharger 5. Use caution when removing and reinstalling the turbocharger assembly. Do not drop it or knock it against anything or grasp it by easily–deformed parts, such as the actuator or rod, when moving it. 6. Use caution when removing and reinstalling the exhaust gas control valve assembly. Do not drop it or knock it against anything or grasp it by easily–deformed parts, such as the actuator or rod, when moving it. The control valve is ceramic. 7. Before removing the turbocharger, plug the intake and exhaust ports and oil inlet to prevent entry of dirt or other foreign material. 8. If replacing the turbocharger, check for accumulation of sludge particles in the oil pipes, and if necessary, replace the oil pipes. 9.
