Prime
Install and tighten the turbocharger oil drain line. Refer to Procedure 010-045 in Section 10.

Lubricate the bearings by pouring 59 to 89 cc [2 to 3 oz] of clean 15W-40 engine oil in the turbocharger oil supply
line fitting.
Rotate the turbine wheel to allow oil to enter the bearing housing.
NOTE: If too much oil is poured into the bearing housing, the oil may leak past the seals. This is not a malfunction
since the seals are not dynamic and rely on exhaust gas and boost pressure to provide a proper seal.
Install the turbocharger oil supply line. Refer to Procedure 010-046 in Section 10.
