Turbocharger with a wastegate (1) Canister for wastegateThe wastegate valve can be checked by applying the pressure that is given in Table 1. Refer to Table 1 for the amount of lift of the wastegate valve that will occur at the given pressure.
Table 1
Amount of Pressure That is Required to Check the Wastegate Valve    
Engine Horsepower     Pressure     Lift    
≤ 230     130 kPa (18.9 psi)    
0.5 mm (0.02 inch)    
≥ 250    
142 kPa (20.6 psi)    
0.5 mm (0.02 inch)    End play for a new shaft ... 0.102 0.025 mm (0.0040 0.0010 inch)Maximum permissible end play for a worn shaft ... 0.20 mm (0.008 inch)Torque for the nuts that secure the turbocharger to the exhaust manifold ... 54 5 N m (40 4 lb ft)Apply 5P-3931 Anti-Seize Compound to the studs. (2) Clamps Tighten the turbine clamp to the following torque. ... 21.6 1.1 N m (16 1 lb ft) Tighten the compressor clamp to the following torque. ... 10.2 1.1 N m (8 1 lb ft)Tap lightly around the circumference of each clamp. Again, tighten the clamps to the respective torque. (3) Exhaust outlet (4) Air inletNote: Put clean engine oil in the oil inlet of the turbocharger after assembly or before installation. This will provide lubrication during start-up and during storage.
