Turbocharger — Precautions (Renault Espace I)

If the oil lines are disconnected from the turbocharger for any reason, before starting the engine, observe the following instructions to ensure the turbocharger receives its initial lubrication:

a) Remove the union nut of the inlet oil pipe connection and pour oil into the turbocharger through the screw holes.

b) Operate the starter briefly until oil begins to come out of the oil feed hose, then tighten the union nut again.

c) Start the engine and let it idle to allow oil circulation to fully re-establish in the turbocharger.
